kernel patches
I 200% agree : that's why I was refering to it :
Is it possible to get a same instructions list for the official
onehttp://git.xenomai.org/xenomai-2.6.git/tree/ksrc/arch/arm/patches/README
?
anyway with a checkout from any branch, I'm not sure that xenomai will
be compiled as from docs, blog, forums, book
it's clearly precise that not all kernel version accept xenomai patches.
Therefore, from my understanding only 1 commit is currenlty guaranteed to
work :
Beaglebone
1- Checkout the am33x-v3.8 branch in the Robert Nelson repository [3],
the patch has been tested with commit
*3fc8a73d782231ab2750ff29793a760e8fa076bb*
2- apply beaglebone/ipipe-core-3.8.13-beaglebone-pre.patch
3- apply ipipe-core-3.8.13-arm-1.patch
4- apply beaglebone/ipipe-core-3.8.13-beaglebone-post.patch
5- you can resume to generic installation instructions.
John: until now I've been just compiled vanilla kernels, -ie no xenomai
worked- could you please indicate what are these steps you have followed to
compile it ?
Way to complicated. Simply clone Robert's linux-dev repo and apply the
attached patch. Build the kernel as normal.

John

If you're wanting a Xenomai kernel, you should:

If you want a plain kernel, pull from Robert's repository and use one
of
the 3.8.13-bone* tags. It's not a branch so when you checkout the tag
you'll get a detatched head warning. You can ignore this (until you
have changes you want to push back upstream) and just build the kernel
as usual.
Why not checkout the am33x-v3.8 branch? That way you can track the
changes
Robert makes to his v3.8 branch. I find it easier to patch Robert¹s
linux-dev repo with your xenomai changes and then I¹m always up to date
with Robert¹s changes. It might be even easier to have Robert add a
Xenomai branch.

[beagleboard] Change Real Screen Resolution
Hi, I'm trying to use a 5.7 LCD screen with Beaglebone Black. I connected the pins and it's working but there is a problem. LCD's resolution is 640x480 and doesn't have an EEPROM. So Beaglebone is setting itself to its defualt resolution, which is 1280x720. I'm trying to change the resolution with: am display-size 640x480 But it doesn't realy change the resolution. It just configure the resolution to look like a 640x480 in a 1280x720 screen. When I look at dumpsys with: dumpsys window it gives me: DisplayContents: Display: mDisplayId=0 *init=1280x720 160dpi* base=640x480 160dpi cur=640x480 ... I think I need to change that init value. I think that value is being set by communicating with LCD's EEPROM. Because when I connect a LCD3 Cape dumpsys window gives init=320x240. Or if LCD doesn't have an EEPROM Beaglebone set itself to its default resolution. I need to change that default resolution. Is there a adb or shell command I can use?

[beagleboard] Re: Adding support for the BeagleBone White DVI-D with audio cape
For the record, the DVI not turning on problem was caused by the excessive pruning of the video modes in tilcdc_crtc.c (see below); in addition when plugging the cable after the beagle had booted, drm_fb_helper.c would ignore any EDID and try to force 1024x768 or any lower resolution. The pruning is unnecessary, I'm not sure why it is done since any mode within the BB bandwidth works fine (the reduced blanking mode is not an issue at all). The attached patch fixes both problems and ensures a 1280x720@60 resolution at all times. Another issue was with omaplfb_linux.c provided in SDK 5.01.00.01. Compiling with PM_SUPPORT=1 FBDEV=yes is required however compilation fails as functions register_vsync_cb() and unregister_vsync_cb() are unknown. I commented the two if blocks and everything works fine after running /opt/gfxsdkdemos/335x-demo (testing with the raw demos provided in the SDK). It's likely those two callbacks are not stricly needed, and will only allow synchronizing frame switching with the monitor's vertical sync. --- 1st issue (all monitor modes being rejected by tilcdc_crtc.c when hotplugging DVI) --- Feb 9 14:36:13 beagle kernel: [ 33.557776] mode 720x576@50 pixel-clock 27000 audio false cea true can_output false Feb 9 14:36:13 beagle kernel: [ 33.565925] Pruning mode, only support reduced blanking modes Feb 9 14:36:13 beagle kernel: [ 33.572013] mode 640x480@60 pixel-clock 25175 audio false cea true can_output false Feb 9 14:36:13 beagle kernel: [ 33.580085] Pruning mode, only support reduced blanking modes Feb 9 14:36:13 beagle kernel: [ 33.586167] mode 720x480@60 pixel-clock 27000 audio false cea true can_output false Feb 9 14:36:13 beagle kernel: [ 33.594238] Pruning mode, only support reduced blanking modes Feb 9 14:36:13 beagle kernel: [ 33.600338] mode 1024x768@60 pixel-clock 65000 audio false cea false can_output false Feb 9 14:36:13 beagle kernel: [ 33.608610] Pruning mode, only support reduced blanking modes Feb 9 14:36:13 beagle kernel: [ 33.614705] mode 640x480@60 pixel-clock 25200 audio false cea false can_output false Feb 9 14:36:13 beagle kernel: [ 33.622880] Pruning mode, only support reduced blanking modes Feb 9 14:36:13 beagle kernel: [ 33.628969] mode 640x480@67 pixel-clock 30240 audio false cea false can_output false Feb 9 14:36:13 beagle kernel: [ 33.637141] Pruning mode, only support reduced blanking modes Feb 9 14:36:13 beagle kernel: [ 33.643260] mode 800x600@56 pixel-clock 36000 audio false cea false can_output false Feb 9 14:36:13 beagle kernel: [ 33.651423] Pruning mode, only support reduced blanking modes Feb 9 14:36:13 beagle kernel: [ 33.657512] mode 800x600@60 pixel-clock 4 audio false cea false can_output false Feb 9 14:36:13 beagle kernel: [ 33.665684] Pruning mode, only support reduced blanking modes Feb 9 14:36:13 beagle kernel: [ 33.672616] mode 1024x768@60 pixel-clock 65000 audio false cea false can_output false Feb 9 14:36:13 beagle kernel: [ 33.680995] 1024x768, hbp=160, hfp=24, hsw=136, vbp=29, vfp=3, vsw=6 --- 2nd issue (failed compilation of module omaplfb.ko from SGX 5.01.00.01) --- CC [M] /root/Graphics_SDK_5_01_00_01/GFX_Linux_KM/services4/3rdparty/dc_ti335x_linux/omaplfb_displayclass.o CC [M] /root/Graphics_SDK_5_01_00_01/GFX_Linux_KM/services4/3rdparty/dc_ti335x_linux/omaplfb_linux.o /root/Graphics_SDK_5_01_00_01/GFX_Linux_KM/services4/3rdparty/dc_ti335x_linux/omaplfb_linux.c: In function 'OMAPLFBWaitForVSync': /root/Graphics_SDK_5_01_00_01/GFX_Linux_KM/services4/3rdparty/dc_ti335x_linux/omaplfb_linux.c:710:7: error: implicit declaration of function 'register_vsync_cb' [-Werror=implicit-function-declaration] /root/Graphics_SDK_5_01_00_01/GFX_Linux_KM/services4/3rdparty/dc_ti335x_linux/omaplfb_linux.c:710:30: error: 'vsync_callback_t' undeclared (first use in this function) /root/Graphics_SDK_5_01_00_01/GFX_Linux_KM/services4/3rdparty/dc_ti335x_linux/omaplfb_linux.c:710:30: note: each undeclared identifier is reported only once for each function it appears in /root/Graphics_SDK_5_01_00_01/GFX_Linux_KM/services4/3rdparty/dc_ti335x_linux/omaplfb_linux.c:710:47: error: expected ')' before 'grpx_irq_wait_handler' /root/Graphics_SDK_5_01_00_01/GFX_Linux_KM/services4/3rdparty/dc_ti335x_linux/omaplfb_linux.c:716:7: error: implicit declaration of function 'unregister_vsync_cb' [-Werror=implicit-function-declaration] /root/Graphics_SDK_5_01_00_01/GFX_Linux_KM/services4/3rdparty/dc_ti335x_linux/omaplfb_linux.c:716:49: error: expected ')' before 'grpx_irq_wait_handler' cc1: some warnings being treated as errors make[4]: *** [/root/Graphics_SDK_5_01_00_01/GFX_Linux_KM/services4/3rdparty/dc_ti335x_linux/omaplfb_linux.o] Error 1 make[3]: *** [/root/Graphics_SDK_5_01_00_01/GFX_Linux_KM/services4/3rdparty/dc_ti335x_linux] Error 2 make[2]: *** [_module_/root/Graphics_SDK_5_01_00_01/GFX_Linux_KM] Error 2 On Sunday, February 9, 2014 1:44:35 PM

Found this thread via google search, so I am probably missing something. But I can't run these commands because I don't know the root password. I can say that on boot with my LCD7, there is really no difference with the Angstrom version. When the calibrate routine comes up at boot, I can click the first target with finger or stylus, but when the second comes up, the only way it will click is if I touch about half an inch to the left. Only once have I managed to click the third target. Usually I get a misclick message and it starts over. If I let it time out, it moves on. If I then touch the screen, the mouse pointer starts shaking. I do have a mouse connected, and eventually this build gives me mouse control back, which is better than the Angstrom build where I had to press reset to get it to stop. This is my first week with this board, and while I'm a long time Linux user, and long time software developer, I am a brand new Linux software developer, so I'm still in the steep portion of the learning curve. I'm following Malloy's guides mostly, in a VirtualBox VM so I can move my dev image around between work and home. Does your wifi adapter work? Are we missing it's firmware? Wicd finds my network via my USB wifi adapter. RaLink RT3572. I can connect, then load chromium and surf the net just fine. I'm a little hesitant to try connman. If it isn't broke, don't fix it... Finally one of my classic setup_sdcard.sh. [debian-7.3-lxde-armhf-2014-01-22.tar.xz] Is there a place I can learn more about this? My eventual goal is to strip this down to a non X system running QT embedded apps on the framebuffer for an embedded kiosk style system. Most of my peripherals are either USB or serial, so my cape will be more like a USB hub than anything else, combining LCD interface and power supplies with the hub electronics and USB to serial chips all on the same board. Around four discrete GPIO inputs and a 4x4 matrix keyboard are about it for other I/O, so I don't anticipate this being terribly difficult. I'm hoping that the USB serial ports will always come up in the same /dev/ttyXXX locations (may have to learn udev for that) but that shouldn't be much different than desktop linux. I really don't see the need for X and a full desktop for this. Wired Ethernet and WLAN (USB) 3G cell modem support will be needed, but not WiFi (using that now just because there is no cable to my kitchen table).

[beagleboard] AVS implementation for Beagleboard in conflict with the normal use of PMC
Dear engineers, I am a user of the BeagleBoard and PandaBoard. Due to the requirements of my project, I want to have a Linux kernel that can support the Adjustable voltage scaling (AVS) through Smart Reflex as well as the PAPI (Performance Application Programming Interface http://icl.cs.utk.edu/papi/) , which is an interface to access the performance monitor counters (PMCs) in ARM processor (support Cortex A8 and A9). Firstly, we have found that the PAPI can be supported in any mainline Linux kernel version above 3.0(PAPI Results 1), including 3.4.0-rc3 and 3.6.0-rc5, the two versions which are used to add Smart Reflext support in Linux kernel. Then we followed the post in http://lists.infradead.org/pipermail/linux-arm-kernel/2012-May/097920.html , to test the AVS on BeagleBoard and Pandaboard. It turns out that both the kernel images obtained from the package : mainline-3.4-voltdm-tps-v1 and mainline-3.6-rc5-omap-tps-v2 can support AVS but fails to support PAPI (PAPI Results 2). In the next step, we obtained the AVS patch and apply it to the Linux mainline kernel version 3.4.0-rc3, 3.4.1 and 3.6.0-rc5, it proved that the patched mainline Linux kernel can now support AVS but fail to support PAPI. To the best of my knowledge, the PAPI functions are successfully inserted in all the above cases. But after the AVS patch is applied, PAPI fails to return meaningful PMC counts. It seems to me that the implementation of AVS somewhat blocks the normal use of the PMCs in BeagleBoard. I am wondering if anybody have been aware of this problem, and it is appreciable if you can share your experience on this issue. PAPI Results 1 (BeagleBoard, under Linux mainline above v3.0, including 3.4.0-rc3 and 3.6.0-rc5): Added PAPI_L1_DCM Added PAPI_L1_ICM Added PAPI_L2_TCM Added PAPI_TLB_DM Added PAPI_TLB_IM Added PAPI_STL_ICY Added PAPI_BR_TKN Added PAPI_BR_MSP Added PAPI_TOT_INS Added PAPI_LD_INS Added PAPI_SR_INS Added PAPI_BR_INS Added PAPI_TOT_CYC Added PAPI_L1_DCA Added PAPI_L1_ICA Added PAPI_L2_TCA Event Counts: PAPI_L1_DCM 64151 PAPI_L1_ICM159362 PAPI_L2_TCM 1883 PAPI_TLB_DM 1835 PAPI_TLB_IM 8 PAPI_STL_ICY 42987476 PAPI_BR_TKN 221854641 PAPI_BR_MSP 91776 PAPI_TOT_INS 2186773029 PAPI_LD_INS 203921167 PAPI_SR_INS 101849208 PAPI_BR_INS 218947812 PAPI_TOT_CYC 1946058572 PAPI_L1_DCA 387448691 PAPI_L1_ICA1228403974 PAPI_L2_TCA220495 multiplex2.c PASSED PAPI Results 2 (under mainline-3.4-voltdm-tps-v1 and mainline-3.6-rc5-omap-tps-v2 ,as well as the mainline version 3.4.0-rc3, 3.4.1 and 3.6.0-rc5 that are patched with AVS patch): Added PAPI_L1_DCM Added PAPI_L1_ICM Added PAPI_L2_TCM Added PAPI_TLB_DM Added PAPI_TLB_IM Added PAPI_STL_ICY Added PAPI_BR_TKN Added PAPI_BR_MSP Added PAPI_TOT_INS Added PAPI_LD_INS Added PAPI_SR_INS Added PAPI_BR_INS Added PAPI_TOT_CYC Added PAPI_L1_DCA Added PAPI_L1_ICA Added PAPI_L2_TCA Event Counts: PAPI_L1_DCM 0 PAPI_L1_ICM 0 PAPI_L2_TCM 0 PAPI_TLB_DM 0 PAPI_TLB_IM 0 PAPI_STL_ICY 0 PAPI_BR_TKN 0 PAPI_BR_MSP 0 PAPI_TOT_INS 0 PAPI_LD_INS 0 PAPI_SR_INS 0 PAPI_BR_INS 0 PAPI_TOT_CYC 1950636665 PAPI_L1_DCA 0 PAPI_L1_ICA 0 PAPI_L2_TCA 0 Caution: 15 counters had zero values Caution: 14 counter pair(s) had identical values multiplex2.c PASSED Thank you very much.

[beagleboard] Re: Beaglebone Black Ethernet Phy Not Detected on Boot.
Can I add in what I'm seeing on a A5C board. When the board boots either with or without an ethernet cable connected I don't get any lights on the ethernet socket. Whereas my older Beaglebone (white version) lights the orange ethernet LED almost immediately after power is applied. I can plug in different cables and different switches into the ethernet port and no go. These cables and switches work fine with the BB white. Appropriate dmesg lines are always the same: [0.762015] davinci_mdio 4a101000.mdio: davinci mdio revision 1.6 [0.762046] davinci_mdio 4a101000.mdio: detected phy mask fffe [0.763087] libphy: 4a101000.mdio: probed [0.763120] davinci_mdio 4a101000.mdio: phy[0]: device 4a101000.mdio:00, driver SMSC LAN8710/LAN8720 [0.763468] cpsw 4a10.ethernet: NAPI disabled [5.682733] gadget: using random self ethernet address [5.888585] net eth0: initializing cpsw version 1.12 (0) [5.890892] net eth0: phy found : id is : 0x7c0f1 [5.891109] libphy: PHY 4a101000.mdio:01 not found [5.896181] net eth0: phy 4a101000.mdio:01 not found on slave 1 [5.960077] IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready Now here comes the crazy part. The *only* way I've managed to get the ethernet lights to come on is to plug in an ethernet cable directly from the BB white to this BB Black (sometimes this doesn't work first time). Then both the orange and green lights come on and stay on on the Black. Then I get: [ 17.528196] libphy: 4a101000.mdio:00 - Link is Up - 100/Full [ 17.528261] IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready If I set an IPv4 address manually I can't ping between the boards tho. Even tho ifconfig is showing some packets flying around: eth0 Link encap:Ethernet HWaddr C4:ED:BA:7B:EB:F7 inet addr:192.168.5.199 Bcast:192.168.5.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:41 errors:0 dropped:0 overruns:0 frame:0 TX packets:105 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:13493 (13.1 KiB) TX bytes:30970 (30.2 KiB) Interrupt:56 Craziness does not stop there. About 50% of the time I can then unplug the ethernet cable from the BB Black and the ethernet lights (on the now empty port) stay lit. I can then plug a cable in between the BB Black and a switch and see activity on the green LED (orange LED is still lit). But still can't actually get any packets out of it. When I do this no new dmesg's appear. Is this faulty or some symptom similar to what else is in this post? I have tried computer USB power, 1A external DC power and a 2.1A USB power supply. This was observed with the original eMMC software version and I have since flashed it to 2013-09-04 version with no difference. regards, Damon. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

[beagleboard] BBB tilcdc driver for custom lcd panel
I have been using a custom LCD display on a beaglebone black running a 3.8
kernel using the DA8xx framebuffer.
I am now trying a new kernel with the TILCDC DRM driver. So I have built a
new kernel with the TILCDC driver enabled and have disabled DA8xx
framebuffer support.
I have modified my device tree to include the following.
panel {
compatible = ti,tilcdc,panel;
pinctrl-names = default;
pinctrl-0 = lcd_pins_s0;
status = okay;
panel-info {
bpp = 16;
ac-bias = 255;
ac-bias-intrpt = 0;
dma-burst-sz = 16;
fdd = 0x80;
sync-edge = 1;
sync-ctrl = 1;
raster-order = 0;
fifo-th = 0;
invert-pxl-clk;
};
display-timings {
native-mode = timing0;
timing0: 480x800 {
bpp = 16;
clock-frequency = 2800;
hactive = 480;
vactive = 800;
hfront-porch = 1;
hback-porch = 20;
hsync-len = 1;
vback-porch = 11;
vfront-porch = 9;
vsync-len = 10;
hsync-active = 1;
vsync-active = 1;
};
};
};
The display timings and pinmux settings are the working values from the
DA8xx framebuffer.
On booting the kernel I get the following snippets.
[1.273229] [drm] Initialized drm 1.1.0 20060810
[1.784763] [drm] Supports vblank timestamp caching Rev 2 (21.10.2013).

[1.817647] [drm] Initialized tilcdc 1.0.0 20121205 on minor 0
running fbset gives me the following info

timings 0 0 0 0 0 0 0
accel true
rgba 5/11,6/5,5/0,0/0
endmode
Obviously the timings are wrong.
I have the following listed in /sys/class/drm
lrwxrwxrwx1 root root 0 Jan 16 07:17 card0 -
../../devices/ocp.3/4830e000.lcdc/drm/card0/

lrwxrwxrwx1 root root 0 Jan 16 07:17 controlD64 -

further more.
cat /sys/class/drm/card0-LVDS-1/status
connected
cat /sys/class/drm/card0-LVDS-1/enabled
disabled
My problem is that it is not enabled.
I am assuming I need to pass some sort of video= to the kernel from
uboot, but I have no idea what.
Is there some other configuration I am missing ?
Has anyone else got this driver to work with an LCD panel ?
many thanks
Ben

[beagleboard] AVS implementation for Beagleboard in conflict with the normal use of PMC
Hello every, I am a user of the BeagleBoard and PandaBoard. Due to the requirements of my project, I want to have a Linux kernel that can support the Adjustable voltage scaling (AVS) through Smart Reflex as well as the PAPI (Performance Application Programming Interface http://icl.cs.utk.edu/papi/) , which is an interface to access the performance monitor counters (PMCs) in ARM processor (support Cortex A8 and A9). Firstly, we have found that the *PAPI can be supported* in any mainline Linux kernel version above 3.0(PAPI Results 1), including 3.4.0-rc3 and 3.6.0-rc5, the two versions which are used to add Smart Reflext support in Linux kernel. Then we followed the post in http://lists.infradead.org/pipermail/linux-arm-kernel/2012-May/097920.html , to test the AVS on BeagleBoard and Pandaboard. It turns out that both the kernel images obtained from the package : mainline-3.4-voltdm-tps-v1https://gitorious.org/omap-pm/omap-pm-work/source/fe55d2d3d7b996d67303f73a47b21eb157e9b9ed:# and mainline-3.6-rc5-omap-tps-v2https://gitorious.org/omap-pm/omap-pm-work/source/e5c892271258e94b06a22b51dc7e6e5e6a4bd090:# can support AVS but fails to support PAPI (PAPI Results 2). In the next step, we obtained the AVS patch and apply it to the Linux mainline kernel version 3.4.0-rc3, 3.4.1 and 3.6.0-rc5, it proved that the patched mainline Linux kernel can now support AVS but fail to support PAPI. To the best of my knowledge, the PAPI functions are successfully inserted in all the above cases. But after the AVS patch is applied, PAPI fails to return meaningful PMC counts. It seems to me that the implementation of AVS somewhat blocks the normal use of the PMCs in BeagleBoard. I am wondering somebody have been aware of this problem, and it is appreciable if you can share your experience on this issue.

[beagleboard] Kaoss-bone. Project idea.
Hi guys, I'm taking a module in real-time dsp at my uni. I'm trying to come up with an idea for a final project. I was thinking of creating my own very simple Kaoss pad. For those of you who don't know what one is, here's a link http://www.youtube.com/watch?v=owkeBOcC-AQ. I just want to do simple FX processing. I have an audio cape for my board. I also have a broken Mac book pro and was planning to use the multi-touch track pad as a controller for the fx. If I could get that working I could have a lot of fun, but I've no idea how difficult it would be to hack this. Dose anyone have any experience with this? Maybe the project is a bit too ambitious... -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

First, there is a newer release of this test image posted here: https://groups.google.com/d/msg/beagleboard/D1ioNrzzXfQ/LdfJ2ccuiY4J Found this thread via google search, so I am probably missing something. But I can't run these commands because I don't know the root password. The root password is blank, the default user's debian password is temppwd this should be detailed on the serial prompt login. I can say that on boot with my LCD7, there is really no difference with the Angstrom version. When the calibrate routine comes up at boot, I can click the first target with finger or stylus, but when the second comes up, the only way it will click is if I touch about half an inch to the left. Only once have I managed to click the third target. Usually I get a misclick message and it starts over. If I let it time out, it moves on. If I then touch the screen, the mouse pointer starts shaking. Please retry with last week's image, there was a few xinput fixes pulled in.. I do have a mouse connected, and eventually this build gives me mouse control back, which is better than the Angstrom build where I had to press reset to get it to stop. This is my first week with this board, and while I'm a long time Linux user, and long time software developer, I am a brand new Linux software developer, so I'm still in the steep portion of the learning curve. I'm following Malloy's guides mostly, in a VirtualBox VM so I can move my dev image around between work and home. Does your wifi adapter work? Are we missing it's firmware? Wicd finds my network via my USB wifi adapter. RaLink RT3572. I can connect, then load chromium and surf the net just fine. I'm a little hesitant to try connman. If it isn't broke, don't fix it... Finally one of my classic setup_sdcard.sh. [debian-7.3-lxde-armhf-2014-01-22.tar.xz] Is there a place I can learn more about this? ./setup_sdcard.sh --help More docs here: http://elinux.org/BeagleBoardDebian#Debian_Stable_.28wheezy.29 My eventual goal is to strip this down to a non X system running QT embedded apps on the framebuffer for an embedded kiosk style system. Most of my peripherals are either USB or serial, so my cape will be more like a USB hub than anything else, combining LCD interface and power supplies with the hub electronics and USB to serial chips all on the same board. Around four discrete GPIO inputs and a 4x4 matrix keyboard are about it for other I/O, so I don't anticipate this being terribly difficult. I'm hoping that the USB serial ports will always come up in the same /dev/ttyXXX locations (may have to learn udev for that) but that shouldn't be much different than desktop linux. I really don't see the need for X and a full desktop for this. Wired Ethernet and WLAN (USB) 3G cell modem support will be needed, but not WiFi (using that now just because there is no cable to my kitchen table).

[beagleboard] Understanding i2c on BBB: a different approach : help needed
Hi All, I'm an experienced rtos driver developer but new to linux i2c subsystem :) For quite some time I was trying to learn i2c subsystem by looking at sources... but may be its way too much for me to understand the terminologies : bus driver/adapters/clients... I keep confusing between them... which is i2c controller driver out of them... what are adapters so on and so forth. I decided to work on it practically and understand it completely for once and all ofcourse with community support. Below is the plan I have for this: 1. remove i2c support from BBB kernel sources 2. add one by one after understanding what is being added 3. final aim is to make one RTC and eeprom over i2c to work with BBB For step 1, I would be grateful if some one could tells us what files I need to remove and what those files do an outline. I think this sort of understanding many newbies in kernel would like to have. I call upon them to add on this thread with related info.

Re: [beagleboard] Control hardware from webserver
I'm new to web applications as well, hence the question. Clarification question: When using the web sockets protocol, the client and server are running on two different pieces of hardware, correct? If so, that's great, because this is the general direction I am heading in with this exercise, however (and I should have been clear on this) my current situation is that I am hosting the php page on the bbb in the /home/ubuntu/public_html folder with the binary executable in that folder as well. In this case, would it be best to do what Rusty suggested and create a group with write permissions to the device nodes and a udev rule that set up the devices to have write permission by that group? I would like to explore both options. After a quick Google search on web sockets, I came across libwebsockets. Would this project implement the web socket protocol you mentioned? Any suggested reading material (even if I need to buy it) would also be appreciated. Thanks again!

[beagleboard] Re: microSD card reader snapped off one side, bad solder joints?
The card was just being inserted like normal--no excessive force. Like I said even before it broke the SD reader wasn't working. When I held the boot button down and applied power the Beaglebone never flashed any lights to show it go through booting (even after waiting 10+ seconds with the button held down). After fixing the solder joints on the SD reader the exact same SD card booted up just fine on the first try. Clearly there was something wrong with the joint before it broke. Also for what it's worth I'm noticing wonkiness with the USB connector which is near the SD card reader. When I plug devices like mice, etc. in and run lsusb I don't see any new USB devices. Going to try testing the USB connections with a multimeter to see if they're all connected.

Re: [beagleboard] Re: microSD card reader snapped off one side, bad solder joints?
Yes, the issue is not that USB connector. Hot plug has been talked about for a very long time. If adding an extra drop solder would fix that, I would certainly make that happen.

I'm not able to get internet access from the BBB, but if I visit the ip address I can see my BBB's website WTF? This is total insanity!!! 169.254.x.x are IPv4 link-local autoconfigured addresses. i.e. the BBB didn't get a DHCP response and picked a random 169.254.x.x address itself instead. It should still broadcast for DHCP, so if your DHCP server ever starts handing out addresses it should pick one up and start working.

You can try the TI Linux SDK user guide/release notes for more details.

Re: [beagleboard] USB OTG Host mode with BBB?
Hi There I am too trying to make the mini usb port to work as a host. I am trying to scan the expansion port signals it seams like none of the pins offers direct access to the processor vbus signal. Should I do this with some software? If with software; what time should it work to enable/disable the volt? And should it listen to the signal all the time or just during the port initialization stage? Best Regards Mahammad On Wednesday, August 21, 2013 4:38:47 AM UTC+2, AndrewTaneGlen wrote: Understood.

Gerald On Tue, Aug 20, 2013 at 9:33 PM, AndrewTaneGlen andrewt...@gmail.comwrote: Thanks Gerald, That was one thing I was not absolutely clear on. The TRM has the following passage concerning USB power control: *When any of the USB controllers assumes the role of a host, the USB is required to supply a 5V power* *source to an attached device through its VBUS line. In order to achieve this task, the USB controller* *requires the use of an external power logic (or charge pump) capable of sourcing 5V power. A* *USB_DRVVBUS is used as a control signal to enable/disable this external power logic to either source or* *disable power on the VBUS line. The control on the USB_DRVVBUS is automatic and is handled by the* *USB controller.* (AM335X TRM, pg. 1697) So are you saying, in addition to the above, that the USB port must be in control of the VBUS enable - assumedly detecting the voltage as off when disabled, and on when enabled, with specific timing requirements around these edges - so that there is no way to simply have the 5V there the whole time? If this is the case I guess there is a chance that I could add some kind of gpio control through the expansion header to enable/disable the 5V rail as and when required (or I could just modify the board - but I'm trying to avoid this and be able to just plug my clean BBB into my horrible looking base board...)

Take a look at the host port design. Both ports are actually OTG ports by design. To make the state machine in the HW function as a host, you need to make it work like the other OTG port, the one we call the Host port, which is configured for host.. Gerald On Tue, Aug 20, 2013 at 9:12 PM, AndrewTaneGlen andrewt...@gmail.comwrote: Hi All, I've been playing around with getting the mini-USB pc connector to function as a second USB host (I'm using RCN's Ubuntu, Raring, but I'd assume this would apply to Angstrom as well). There is a post here http://pansenti.wordpress.com/2013/05/27/ beaglebone-black-with-two-usb-host-ports-it-can-be-done-but- its-not-easy/ decribing how to do this with some hardware modifications, but looking at the AM335x technical reference manual it looks like I should be able to set USB Port 0 to function as a host through software alone (i.e. without needing to ground the USB ID pin, or to modify anything else on the board). So what I have done so far is modify the 'am33xx.dtsi' file under the 'usb_otg_hs' section, and change the item 'port0-mode = 3' to 'port0-mode = 1', which, according to 'am33xx-usb.txt' in the device tree documentation, should force this port to function in Host mode. I then had a look through menu config, in the 'Device Drivers' - 'USB Support' section and there didn't seem to be anything specifically relating to setting the mode of any particular usb port, so I left all of this unchanged. Upon booting I can see that whereas previously I would get the following wit regards to USB0: musb-hdrc musb-hdrc.0.auto: *** mode=3 I now get musb-hdrc musb-hdrc.0.auto: *** mode=1 This would appear to indicate that my device tree change had been successfully applied, and the initialisation of USB port0 now looks identical to that of port1. whereas previously they were quite different. I then customised my USB cable to have an external 5V feed (wired to SYS_5V on the expansion header) and added a female-female USB A adaptor to give me a host socket. However, it doesn't work. I have checked the power rail and can see 5V on R159 on the bottom of the BBB and I have double checked that the comms wires are the correct polarity, and everything buzzes out as expected. The device boots, and I can SSH into it. Plugging a memory stick into the standard usb host plug causes messages related to detecting and attaching a disk, but when I plug the same disk into the modified connector assembly I get noting at all.
