Re: [beagleboard] Removing I2C2 from kernel
omap3beagle is for BeagleBoard and BeagleBoard-XM, don't touch this file as for I2C you need to change pin mux settings for particular pins. I think it's even possible to change the pin mux settings right in the working OS, using the /sys directory. Unfortunately I don't know how 2014-07-29 2:53 GMT+04:00 fes...@googlemail.com: Hi there. I would like to use both CAN0 and CAN1 on my beaglebone black. I followed tutorial on this page; http://www.embedded-things.com/bbb/enable-canbus-on-the-beaglebone-black/ CAN0 works for a start but the board restarts after a while. Works properly when CAN0 is not used, so I am guessing I2C2 is the problem. http://pastebin.com/L0BLMwYR I think that board-omap3beagle.c kernel file needs to modified.

Re: [beagleboard] unable to boot Beaglebone Black from NFS
Thanks for your help, but sadly, on this version a uEnv.txt just containing; console=ttyO0,115200n8 client_ip=192.168.10.47 server_ip=192.168.10.118 gw_ip=192.168.10.1 root_dir=/home/bone/bbb_nfs_root does not work, it doesn't even fire up the ethernet port (no activity lights), I'm guessing because there is no eth0 defined and its perhaps trying to fire up the USB network or something.

Re: [beagleboard] Re: unable to boot Beaglebone Black from NFS
William Yes I did start with your guide, but could not make it work, then I noticed that the addresses in the uEnv.txt that come with the standard distro did not match the ones in your guide and I'm using the standard kernel, uBoot etc. so I got suspicious and I started looking elsewhere and hacking around. I've now changed mmcargs to netargs and still no joy. I'm going to mess with the ipaddr bit when I get home from work tonight since currently I'm doing a bit more than you with ${ipaddr}:${serverip}:${gateway}:${netmask}:${hostname}:${nfsdevice} instead of just ${ipaddr}. I also noticed in the standard distro it has ${cape_disable} ${cape_enable} ${kms_force_mode} in the mmcargs line, I'm not sure if you also need them when using netargs with this version.

Re: [beagleboard] unable to boot Beaglebone Black from NFS
By the way I was contacted by another party last year who told me that my blog guide for NFS rootfs wont work with Ubuntu, and fedora. But will work for Debian ARCH, and BusyBox. So I have to assume the init daemon for these other distro's are the culprit. However, if you can find a known working guide from anywhere on the web ( i386 guide ) and adapt it . . . you should be golden. Now, if you were willing to switch to Debian on both host and BBB I know it would work if you followed my guide to the T. But perhaps that is too much of a leap for you.

Hi, Thanks for your answer but my board seems to be sleeping. Actually, in the first time I plug my board to the laptop, it works fine with the power light turned on and 4 LEDS operate normally. But I want to install the Ubuntu on it, so I follow the instruction here: http://www.armhf.com/boards/beaglebone-black/bbb-sd-install/ after finished the step g(Finally, commit the changes by selecting w to ‘write’ the partition table and exit fdisk.), I unplugged the usb cable. From that, when I connect the board by USB cable again, then my board is not starting normally anyomre, the OS in my laptop is not showing the notification about new device has been plugged into it and the LEDs are not lighting as well, just the power light in the board turned on. I followed the link you posted but in this, it says that: Use the provided microSD card to SD adapter or a USB adapter to connect the SD card to your computer. So does it mean we have to use the external SD card which can communicate with the board by the SD card slot and use it to to some next steps to boot ? When I receive my board, all I have are just the board without the external SD card and the USB cable ! So in my situation, what should I do to make my board return to the original state ?

Re: [beagleboard] Re: Maximum current on GPIO?
BeagleBone Black System Reference Manual Rev C page 113| (in bright red font): There are several precautions that need to me taken when working with the expansion headers to prevent damage to the board. 1) Do not apply any voltages to any I/O pins when the board is not powered on. 2) Do not drive any external signals into the I/O pins until after the VDD_3V3B rail is up. 3) Do not apply any voltages that are generated from external sources. 4) If voltages are generated from the VDD_5V signal, those supplies must not become active until after the VDD_3V3B rail is up. 5) If you are applying signals from other boards into the expansion headers, make sure you power the board up after you power up the BeagleBone Black or make the connections after power is applied on both boards. Powering the processor via its I/O pins can cause damage to the processor. Those kind of assumptions might kill your board.

Re: [beagleboard] Re: Maximum current on GPIO?
This doesn't answers my question. So to describe it more clear: - board/CPU is powered and running - SYS_RESETn is HIGH - GPIO is configured as input ...so all preconditions mentioned in BBB manual are met. Now when I want to set a HIGH signal to that GPI, can I connect it with BBBs 3.3V directly or is a resistor needed in order to keep this 8 mA sink limit? Am Mittwoch, 30.

Re: [beagleboard] Re: Maximum current on GPIO?
A GPIO configured as an input will not draw substantial current from the line it's connected to. It is sensitive to the charge level on the line and will not draw current from it (exempting the gate capacitor charge-up). A GPIO that is set to OUTPUT a high signal is now a potential source of current. If you hook that up to the + end of a motor it will try to power the motor with the output. In that case you MUST insure that your circuit limits the current to a maximum of 6mA. The same is true if you OUTPUT a low signal. Hook that to the - lead on a motor and the + lead to supply and the CPU is now trying to absorb all the current from that motor and will go poof. So if you were to connect directly to the positive supply and say somehow that pin ever becomes an output that is low you now have a dead short through the I/O pin and at best you'll fry that pin or its whole bank, you'll likely kill the whole chip. Since the I/O on these devices is programmatic I never like to connect a pin directly to the supply rails. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

[beagleboard] BBB Debian Corrupt LCD
We have a built a custom board with an LCD interface to drive a 1024 x 768 pixel LVDS panel, 16BPP. It works great on the Beaglebone White with the old Angstrom 3.2 using the board file configuration. We want to use the Beaglebone Black so we built up a system from http://elinux.org/Beagleboard:BeagleBoneBlack_Debian#2014-07-22 . I added a dts using the same parameters from the old board file but the graphics are blurred and corrupted. The card I made boots on the White also and gives the same results as on the Black. See images below. I’ve fiddled with the panel timings but they don’t seem to have any effect. Does anyone have any idea what is wrong and how do I fix it? Regards, James This is part of the (good) image from the frame buffer. https://lh6.googleusercontent.com/-4paVjDS0NME/U9j9QP7ZvyI/GjY/Tq2jYoa6r0Y/s1600/screen1.jpg This is a photo of the output on the screen, showing a similar area. https://lh6.googleusercontent.com/-qR11mE7KhYU/U9j9wMohRZI/Gjg/_lhBqXIQQyk/s1600/screen2.jpg The following is the panel section of the dts file, based on an LCD4 dts:- /* Settings for AUO G121XN01 / mita cape: */ panel { compatible = tilcdc,panel; pinctrl-names = default; pinctrl-0 = bone_mita_cape_lcd_pins; panel-info { ac-bias = 255; ac-bias-intrpt= 0; dma-burst-sz = 16; bpp = 16; fdd = 0x80; tft-alt-mode = 0; stn-565-mode = 0; mono-8bit-mode= 0; sync-edge = 0; sync-ctrl = 1; raster-order = 0; fifo-th = 0; invert-pxl-clk= 0; }; display-timings { native-mode = timing0; timing0: 1024x768 { hactive = 1024; vactive = 768; hback-porch = 80; hfront-porch= 48; hsync-len = 32; vback-porch = 15; vfront-porch= 3; vsync-len = 4; clock-frequency = 5600; hsync-active= 0; vsync-active= 0; }; }; }; fb { compatible = ti,am33xx-tilcdc; reg = 0x4830e000 0x1000; interrupt-parent = intc; interrupts = 36; ti,hwmods = lcdc; ti,power-gpio = gpio1 2 0x0; ti,allow-non-reduced-blanking-modes; }; -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Re: [beagleboard] BBB Debian Corrupt LCD
If you read the manual, you will see that these lines are also connected to the HDMI chip. To use it also as an LCD panel, you need to buffer these signals and account for any noise that may be introduced as a result of the loading of these 6ma drive signals my the HDMI chip.

Re: [beagleboard] Re: BBB Debian Corrupt LCD
Still could be the same issue. What buffer are you using to drive the signals to the LVDS device? Are the trace lengths match to insure that all the setup and hold times are met by having all signals with the same delay?

Re: [beagleboard] Re: BBB Debian Corrupt LCD
Gerald, The pins are connected directly to the LVDS chip, a DS90C383BMT. Trace lengths are short and matched.

Re: [beagleboard] Re: Maximum current on GPIO?
The gpio are push pull/pseudo open drain, so there's a transistor/switch going from 3.3V to the pin, and a transistor going from ground to the pin. When you set the pin high, you're turning on only the transistor to 3.3V, so it's sourcing the current from 3.3V, through the transistor, out of the pin. When you set it low, you're turning on the transistor to ground, so it's sinking the current into the pin, through the transistor, and to ground. If you have both off (high impedance), there isn't any significant current going anywhere (I think it's some nA). On Wed, Jul 30, 2014 at 6:11 AM, k...@cranehome.info wrote: A GPIO configured as an input will not draw substantial current from the line it's connected to. It is sensitive to the charge level on the line and will not draw current from it (exempting the gate capacitor charge-up). A GPIO that is set to OUTPUT a high signal is now a potential source of current. If you hook that up to the + end of a motor it will try to power the motor with the output. In that case you MUST insure that your circuit limits the current to a maximum of 6mA. The same is true if you OUTPUT a low signal. Hook that to the - lead on a motor and the + lead to supply and the CPU is now trying to absorb all the current from that motor and will go poof. So if you were to connect directly to the positive supply and say somehow that pin ever becomes an output that is low you now have a dead short through the I/O pin and at best you'll fry that pin or its whole bank, you'll likely kill the whole chip. Since the I/O on these devices is programmatic I never like to connect a pin directly to the supply rails. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to a topic in the Google Groups BeagleBoard group.

[beagleboard] Re: Can the BeagleBone Black be used for industrial designs?
As has been mentioned, while it was developed as a community supported platform, the BeagleBone can be used for any application you choose. For a time, there was a lack of sufficient supply to meet the demands of larger scale projects, but that is generally no longer the case. The topic of utilizing BBB for industrial applications is explored further here - http://www.logicsupply.com/blog/2014/05/15/new-embest-board-opens-door-for-beaglebone-black-projects/ As for industrial projects that do not require graphical interface, we're currently working with a number of clients developing embedded solutions based on the BBB. We've outlined the basic building blocks for many of the type of projects we're seeing being developed on our BeagleBone resource site Inspire - http://www.logicsupply.com/blog/2014/07/29/whats-new-inspire-latest-beaglebone-black-projects/ I hope your project has taken off in the last year.

Can the BBB be used for applications that do not require visual interface like LCD or keyboards ? Like controlling a stepper motor, accepting logic signals from external hardware ?? 3. A basic scheme I have in mind is, when BBB boots on power up, instead of desktop or a command line begin loaded an application (code by me) will be loaded, this application will then manage various tasks like monitoring input ports, flashing some LEDs etc. Is the above scheme possible with the BBB ??

Re: [beagleboard] Beagleboard-xm avaliability
They only sale though distributors so it is up to the distributor to handle this.The idea of setting up a production line, loading the parts to build one board would make the cost of this board around $500. Orders would need to be entered by the distributors. I am not sure any of them would be willing to order 1500 boards just so they can sell you one board. It is basic supply and demand. If we have real demand then we will supply. If you want one board ask around the community and see if anyone has one to sale.

[beagleboard] RevC Web Browser when booting from SDcard 5/14/14 image
I downloaded the latest boot from SD card image(5-14-14 ) image and it boots fine. I can Putty and WinSCP to it also. The issue I am having is when I run the included web browser it will either open and crash right away or will open an allow a couple of clicks and then it is gone. I am not sure if it is crashing or hiding but if you keep trying to re-run it after a couple of times it does not even open. Also when I logged out after doing this it shutdown fine but when I tried to reboot the image on the SD card was corrupt indicating missing modules I re-imaged the SD card and it again boots fine and has same Web Browser issue The Web Browser is Chromium on this image. When I boot the flash emmc image that is on the board I do not see this issue with the Chromium Web Browser I was able to get Cloud9 running. I am booting with a mouse, keyboard and external monitor and networked to my home router. Does anyone else see this issue Thank's Tom -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Re: [beagleboard] Re: RIP Never Used BBB
But, our goal was as low a price as we can get. Adding a protection against all the things that could happen means it would have to be water poof and withstand 220 VAC on the input. That is more than $10 to $12. Reading the manual and the wiki is free.

[beagleboard] analogy Gyro breakout help?
I'm having a heck of a time figuring out the Gyro-py breakout. https://www.sparkfun.com/products/11341 I have it hooked up in to p9_40, and I can't figure out how to get it to read correctly.

Re: [beagleboard] BBB Rev C: Debian: PureJavaComm/JNA test fails

Re: [beagleboard] Re: RIP Never Used BBB
I wasn't saying make it bullet proof, just some simple goof proofs. Like on the 5v plug, that kind of thing. I get the whole cost thing and by and large agree. I'm sure to try and cover everything would cost a bit, Not sure why anyone would be putting 220v to the 5v plug, but i could understand reverse polarity on the 5v plug. Not sure it needs to be gone to the extreme. How hard/costly is it to fix something like reverse polarity or blown gpio? if repairs are easy enough, perhaps protection isn't worth it.

Re: [beagleboard] BBB Rev C: Debian: PureJavaComm/JNA test fails
You might want to try libbulldog (http://www.libbulldog.org). Here's an example: http://libbulldog.org/bulldog/examples/serial-example/ It can do advanced Serial communication as well, but has not been tested on Debian. By advanced I mean settings things like setting parity, databits and stop bits. Maybe that is sufficient for you. But you'll probably have to tweak the Java side a little, I don't know if the Debian devices match the angstrom serial devices. What I can say about the error, though, is, that you will also get it, when the binary format does not match your system. Am Mittwoch, 30.

Re: [beagleboard] Re: RIP Never Used BBB

[beagleboard] What are the 'dmidecode' and 'lspci' equivalents on ARM?
For no reason I want to just explore the system and its details. I came across this command 'dmidecode' which is supposed to dump all the hardware information. It did not work on BBB and I did some searching on google and on one of the ARM forums it has been mentioned that 'dmidecode' does not work on ARM systems and people over there were still discussing on what can be done regarding this. I do not want to dive too deep for now. All I want to see is details about the BBB. I have tried lscpu, lsblk, lsusb. Things that did not work were dmidecode and lscpi.

[beagleboard] Rev C processor in adafruit website - AM3359 ?

But in my kernel sources (3.8.13) this file doesn't exist. There is no board files since the introduction of device tree. What would be the right way to use SPI in my kernel module? Look at examples in /drivers/staging/iio or /drivers/iio There are plenty of examples of using SPI calls in a kernel module. Use the power of GIT to find what you are looking for.

Not sure it needs to be gone to the extreme. How hard/costly is it to fix something like reverse polarity or blown gpio? if repairs are easy enough, perhaps protection isn't worth it. Think economics and not technical. Since there were very few returns because of reverse polarity, it isn’t cost effective to add the protection to each board. For example, circuitco has shipped 177,000 BBB multiplied by $10 protection is $1,770,000. Less than 20 returned because of reverse polarity at $55 each is $1,100. The solution is obvious. Gerald is very smart and he knows what he is doing ;-) Users just need to be more careful.

Since there are very few of you who have done this, why should the rest of us have to pay the extra cost. I think there are less than 20 out of 150,000 boards shipped.

Re: [beagleboard] BBB Rev C: Debian: PureJavaComm/JNA test fails
Does the file exist at that location? You seem to be trying to run your app as root, so its not a permission problem. Also from memory /tmp/ will not persist between reboots. SO perhaps not the best place to put any file that is needed long term. On Wed, Jul 30, 2014 at 2:32 PM, Datenheld datenh...@gmail.com wrote: P.S.

It stuns me anyone would plug in power without verifying the polarity is correct. The way I see it, it's kinda like the Darwin Awards. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.
