Re: [beagleboard] Crashing accessing mmap location

The easiest workaround is to export one pin from each of the modules using /sys interface: https://groups.google.com/d/msg/beagleboard/OYFp4EXawiI/Mq6s3sg14HoJ Here is a short script which does the job: https://github.com/piranha32/IOoo/blob/master/tools/bbb_enable_gpio.sh Regards, j.

I don't see any meaningful difference (except price). The answer isn’t so simple. The DM3730 used on the Beagleboard-xM is more powerful because of the additional DSP, but there is currently no support in the current Linux kernel for the DSP processor. The DSP was supported in Linux kernel up to V3.4, using SysLink to communicate between the ARM processor and the DSP. SysLink has been replaced by RPMSG/RemoteProc, but there is currently no support for the DM3730. The new Beagleboard-x15 will be supported. However, the BBB with the TLV320AIC3104 audio cape does work, but if you require a microphone, you will need additional circuity because the audio cape does not support bias voltage required by the microphone.

I never ran it this way so I am not sure what might prevent it from working this way, but the following stack overflow discussion might be helpful: http://stackoverflow.com/questions/506805/binary-data-over-serial-terminal printf(ERROR : tx not send.\n); else for(unsigned int i = 0; i sizeof(tx_buf); ++i) { std::cout std::hex (int)tx_buf[i]; } printf( : tx send \n); You do realize that the 'else' block contains just the for() {} loop and not the printf statement? (your indentation seems to indicate otherwise) I recommend using curly braces always even if the conditional block has just one statement. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Its a bit like this thread, one of the first I read about BBB https://groups.google.com/forum/#!searchin/beagleboard/hermans/beagleboard/951nWp_Jcnc/ZZV0GPwB3z8J Eye opening, anyone asks a question or queries anything and they get flamed along the lines of We developed this board for free and you expect our knowledge for free yet there is no option to get any knowledge other than as you and other point out in that thread Google. You guys seem to be offended if someone doesn't want to use the command line vis ssh. You do realise its 2015? We or any BBB newbie are not asking for our hands to be held, just a few pointers. The work we did on the Arduino is now being packaged as open source, thats a fully working implementation of CanOpen geared specifically towards motor / servo control, it will save devs months of work. Anyway, I do understand the OS, no need for the snide superior attitude, we are prototyping, you surely understand the concept? Spend little, develop fast, then invest in custom PCB's etc. The BBB has a fairly powerful CPU and CAN bus, it ticks a lot of boxes for us. We are a start up not Microsoft or Tesla, FFS (to paraphrase you). We were just a little surprised to find basic issues with running off a 5v supply, has to be a very clean supply, not just any 5V 2A supply. Basically we had a lot of teething problems, which we have mostly had to work around, not solve. The issue of USB connectivity: its a lot more convenient for us to just use USB for demo / mobility purposes, rather than having two cables plugged into the BBB, ethernet USB. For our fixed machines, I agree it's not a problem, but for those using laptops, its a bit of a nuisance. Forgive me for complaining about the lack of documentation. Case in point: Take the LSM303, finding coherent instructions was difficult. I bought Derek Molloy's book and we are now tearing ahead, his instructions are consistent. Infant we bought heaps of books (all I could find) on the BBB, if you go through them, there are discrepencies even in basic set up.

linux pc run dhclient -i usb0 2015-02-06 20:28 GMT+00:00 jseb...@gmail.com: Forgive me if this issue is resolved elsewhere, I've looked but couldn't find a solution. I have a BeagleBone Black, running the latest BeagleBone Debian distribution. I had been running Debian Wheezy 7.8.0 on a desktop, and had been able to ssh into the BBB from the Gnome desktop terminal. However, I recently moved to Debian Jessie, the Testing distribution, and cannot get the BBB to work. I have tried all the different desktop options available, Gnome, KDE, Cinnamon, etc, and what happens every time is that the BBB is mounted and I can peruse the boot folder, however I cannot access the 192.168.7.2 address at all, and 192.168.7.1 isn't listed by ifconfig either. Is there something simple I am missing that is keeping the BBB from working here? I am fairly inexperienced with Linux, so I would guess this is so. I am also pretty certain the BBB isn't to blame, as it works when plugged into my Windows desktop... it grabs the 192.168.7.2 ip address, and is accessible through ssh and the web page. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Well , maybe you can try this ? http://pastebin.com/pkTf7xfJ from this thread http://www.raspberrypi.org/forums/viewtopic.php?f=41t=33679 BTW , I dont think SSD1289 is a good choice , if you are in BBB platform . when we talking about DISPLAY , there two things , called source driver and gate driver . like LCDC , you can consider it as source driver , while TFT panel , you can consider its a gate driver . for several years ago , there is no LCDC integrated in arm SOC , So solomen and epson (As I know ) will have some modules integrated LCDC and SRAM (Framebuffer) and TFT gate driver And only memory space is enough , you can connect like sram(M68K MODE ) .or NAND (8080 MODE ,IO MODE) the benefit is 1) no lcdc need ,2)on module integrated sram used as framebuffer takes few bandwidth (static screen ,no content change ) will not cost main memory bandwidth But in BBB board, since you have already got a LCD controller , and the memory bandwidth is definitely enough , I suppose a TFT panel is enough . -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

It saves you amplifier design for driving speakers and has stereo Headphone ports. Needless to say, with class D amplifier you get the lowest power consumption possible compared to class AB etc. If you need stereo speaker output consider TLV320AIC3110. Okay, good. I found that IC in my research, thought it might be useful. (is I2S the same as your I2c2?) No, TI calls I2S, Inter IC Sound, McASP which is a four wire bus. I2C is Inter-Integrated Circuit and is a two wire bus. For codec you need both of them. You need I2C for programming the registers and I2S for transmission of voice. I realized after reading more that i2c2 must've been the Sitara's I2C bus #2, and that I2S support was provided by McASP. Could I ask you additional questions as I get further into this? That's what forum is for. It is pretty simple. Just connect your I2C and I2S to micros I2C and McASP, do the procedure that I wrote above, and you are done. Awesome, thanks!

As far as I know the only patches they used are agains dts/dtb files (I use the same ones) and to configure the kernel without the need of using makeconfig. So far so nice...the system boots with a Gentoo stage3 rootfs. There only two things left: 1.) shuthdown -h -H now (as said to be used by Acmesystems) reboots the system instead of powering it off (which works with their image). 2.) The at91 RTC is missing the Real...the difference are several minutes per hour. I compared the dmesg output of the Arietta G25 booted with one and the other system. With the Gentoo system there is one line which irritates me and may indicate a way to a solution for the RTC problem: [0.00] Main crystal frequency not set, using approximate value [0.00] master clk is overclocked [0.00] sched_clock: 32 bits at 128 Hz, resolution 7812500ns, wraps every 167772160ns [0.00] Console: colour dummy device 80x30 [0.054687] Calibrating delay loop... 220.07 BogoMIPS (lpj=862208) The clock frequency of the CPU is unknown???

Re: [beagleboard] Re: JavaFX 8 on BeagleBone Black (SGX driver problem?)
I have tested Ti gpu driver on omap5 uevm board based with GLSDK 6.04 The gpu driver crash didn't be fixed for a very long time . iMX6 GPU will crash also ,if high cpu load and very frequency interrupt case, you might get kernel panic on imx6-solo but on fsl QUAD cores , Its more stable , maybe because of their gpu kernel driver is based on work queue . . But for FSL kernel driver . lack of I2C /SPI dma support , if you want use very high spi through put , like DMB/CMMB chip always do You will get poor performance . 2014-12-01 11:39 GMT+08:00 Nick Apperley napper...@gmail.com: Presumably the closed source driver is an installer that is run on any Freescale imx6 board.

Re: [beagleboard] serial UART async_low_latency does not seem to work. still 10ms latency!
Finally CONFIG_HZ will take effects the scheduler Assuming you use default 32k clock source .from default kernel config and source . And what I guess if you get delay about 10ms , you might get a delay schedule on 128HZ in default config So , If you use 1024HZ ,you can get about 1ms latency . And if the data is very frequency , fifo will not be the problem , what I just guess , if you only send several bytes in a peak time . fifo might be not enough to generate an interrupt . there is a 64 BYTES fifo in omap uart host controller . If this case just for bluetooth like skip fifo setting , just use 1024HZ ,it should be solve 2014-11-26 11:40 GMT+08:00 William Hermans yyrk...@gmail.com: This is for UART ?

I would imagine the Debian team wants the technology proven before they make the leap. From what I understand, the next iteration of Debian *will* include systemd, and it is an apt-get-able package for wheezy right now. Also according to what I've read, it will work right along side SYSV, or at least init scripts, with no harm to anything, except perhaps slower boot times ( versus just using systemd by its self ). If you really want to know about it, I would suggest you do a bit of googling. There is lots of information out there about it, it is just that I have not been able to find a decent simple example of how to setup services yet. This is either because I'm not searching for the correct thing, or the documentation on the whole process is jut limited right now. The key point, is if Debian is going to move to using it, it is probably worth researching yourself.

From what I understand, TI made the choice of supporting 3.13.x branch with the SGX hardware. capremgr was in 3.8.x, and based on Roberts guide, 3.15.x has better ethernet, and usb support. As for why the branches are done this way ? I'm not a kernel developer so I'm not 100% sure. However I could imagine that it is a lot of work setting all this up plus scripts / instructions for building etc. I've seen Robert say several times patches welcome, so I'm assuming he may not wish to duplicate his own work across branches. But this is just speculation on my own behalf. I'd be willing myself to work on getting capemgr as is working on 3.8.x into 3.15.x myself. But since I'm fairly inexperienced in this area I'd need time, and a mentor ( as in to guide me, not to pay me ).

From what I understand, TI made the choice of supporting 3.13.x branch with the SGX hardware. capremgr was in 3.8.x, and based on Roberts guide, 3.15.x has better ethernet, and usb support. As for why the branches are done this way ? I'm not a kernel developer so I'm not 100% sure. However I could imagine that it is a lot of work setting all this up plus scripts / instructions for building etc. I've seen Robert say several times patches welcome, so I'm assuming he may not wish to duplicate his own work across branches. But this is just speculation on my own behalf. I'd be willing myself to work on getting capemgr as is working on 3.8.x into 3.15.x myself. But since I'm fairly inexperienced in this area I'd need time, and a mentor ( as in to guide me, not to pay me ).

Re: [beagleboard] BeagleBone Black with thunderbolt
If I can suggest , for storage system , you can try banana pi board . http://www.bananapi.org/ It will have sata and 2 cortex-A7 cores 2014-07-22 8:05 GMT+08:00 eagletree eagletr...@gmail.com: Thanks very much for the reply. I kind of suspected that. The thunderbolt works well with the recent mini-macs and I already have it connected to one as a backup device, it would be simple enough to export on NFS and that would do the job. The way I'm planning the app, there would be multiple BBBs accessing the file system plus they would use standard db IO for sql. Given that each BBB would be handling a single web service request (start to finish of one state), I think NFS would be adequate. I had just hoped to take advantage of the raw performance of the Areca RAID we use. You've settled the architecture for me and it's easier to set up a prototype this way. Thank you. On Monday, July 21, 2014 10:44:27 AM UTC-7, William Hermans wrote: I'm not a Thunderbolt expert, but I think the bottleneck here ( assuming the BBB had access to PCI-E ) would be the CPU. I have been following the concept several years before implemented in consumer product, I still do not know the actual specification, but I am fairly certain the BBB does not have fast enough, or even enough I/O to do Thunderbolt. However, the BBB *can* load the kernel and root file system via USB, NFS, and MMC media at minimum. I've done all 3 of the above, and they a work very well. The on board Ethernet is exceptionally fast when compared to some PC implementations. The USB hardware I tested was nearly twice as fast at writes, but slightly slower at reads( comparedto NFS ). This may / may not have had to do with my external USB media though. iSCSI also worked, but was not faster than NFS. Since NFS is considerably easier to setup, I pretty much gave up on iSCSI.

Is there any possibility that someone is working on a cape that could access thunderbolt for disk array connections?

Re: [beagleboard] BBB's memory is messy?
From eMMC spec 4.3, eMMC will have 2 boot partition called boot partitions , and general partition called user partition For robust disign , Boot partition will not be able to use wear leave . so it should be use as SLC design (against user partition MLC )and make a backup And on Ti chip , these 2 partition CAN NOT used as boot partition , while in FSL and QUANTUM , their boot rom can boot from these 2 (only depend on the boot flag in extCSD[179]) You can read the imx 6 Reference manual for more detail about this . 2014-05-29 11:28 GMT+08:00 jiapei100 jp4w...@gmail.com: Hi, all: Sorry for dropping this stupid question. But, with my TF card plugged in, I checked the memory of BBB (Refer to the bottom command) It looks BBB's memory is quite messy.

Re: [beagleboard] Re: [beagle-alpha] help, I think the smoke escaped from my beagle stack (beagle white, battery cape, dvi cape, audio cape)
Hello Gerald How to do RMA ? I am in Shanghai 2014-05-19 20:51 GMT+08:00 Gerald Coley ger...@beagleboard.org: Do the RMA. Gerald On Sun, May 18, 2014 at 9:13 PM, Eric Fort eric.f...@gmail.com wrote: Help, I just got an audio cape today and wanting to get it working I added it to the top of the cape stack such that I had a beaglebone white, the battery cape, dvi cape, and finally the new rev b audio cape on top. a couple days ago I used this setup without the audio cape running on batteries and it worked completely as expected. I plugged it into the network and used the stack over ssh for over 3 hours as commented in a previous post. Today, I was a bit short on batteries so after carefully looking over the battery cape SRM found here https://github.com/CircuitCo/BeagleBone-Battery/blob/master/BeagleBone-Battery-RevA-srm.pdf?raw=trueand determining that it will accept from 1.8-5.5V across VBAT as doccumented on page 16 of the cape SRM I reviewed the schematic to find J8 J9 allow attachment to VBATT such that I may attach a power supply to J8 or J9 for power. I then placed 2 AA cells in the battery holders on the battery cape and measured the voltage across J8 J9 to determine proper polarity after which I attached a black lead to the minus or negative terminal and a red lead to the positive terminal. it blinked and flashed nicely as I would wxpect at this point as if trying to boot. I then attached a 5V power supply to these terminals checking for proper polarity prior to turning on the supply which I measured at 5 volts. I only took this option because after careful reading of the Battery cape SRM It stated that 5v is in spec. well the board stack failed to come up or give any indication of life, not so much as a power LED on any of the boards! then about 15 seconds elapsed and things started to smell. I pulled power shortly thereafter. now all that happens when I put batteries in the battery cape in the batteries get too hot to hold in just a couple seconds and the smell returns. trying to power the beaglebone over USB with no other capes attached blinks the power LED but no other evidence of life is seen. I am also suspect of the audio cape and dvi cape possibly being fried as well. are there some additional things I can and should check or is this something for direct RMA?

Re: [beagleboard] Clear CPU caches for reading system timer on beaglebone
https://groups.google.com/forum/#!searchin/beagleboard/$20Clear$20CPU$20caches/beagleboard/ypXbgkmkAek/GaCqAyAWREkJ 2014-05-18 0:32 GMT+08:00 fis.ir...@gmail.com: Hi, I am using TI AM335x BeagleBone, Linux kernel version 3.8.13. My aim is to get fast and reliable time values from user-space using dmtimer. When I I read (and print) tick values of DMTimer2 though /dev/mem, I have the following: 3146348594 3146350438 3146352109 3146357959 3146360117 3146361773 3146363376 3146364986 3146370527 3146374221 3146376003 3146382901 3146384741 3146386379 However, when I invoke device driver with mmap operation and then in user space interact with this device, I have a strange behavior. Ticks are repeated periodically: 2296380051 2296386006 2296386006 2296403883 2296412958 2296423574 2296423574 2296438010 2296438010 2296438010 2296457840 2296468548 2296468548 2296482669 2296482669 2296482669 2296482669 2296507701 I am not sure, but it looks like L1/L2 caches are overflowed. My question is what can cause this behaviour. And if it is CPU caches, how they can be cleared. I found this answer How to clear CPU L1 and L2 cachehttp://stackoverflow.com/questions/3446138/how-to-clear-cpu-l1-and-l2-cache, but I doubt how I can apply this method. Do you have any suggestions? I will appreciate any help. If it is necessary, I post here briefly the way how I obtain these ticks vs driver. 1. remapping of a specific region in kernel space (0x4804 - DMTIMER2 register start address): static int simple_remap_mmap(struct file *filp, struct vm_area_struct *vma) { unsigned long off = vma-vm_pgoff PAGE_SHIFT; // generate the correct page frame number unsigned long pfn = (0x4804 + off) PAGE_SHIFT; // vsize is the requested size of virtual memory unsigned long vsize = vma-vm_end - vma-vm_start; // psize is the physical I/O size that is left after the offset has been specified unsigned long psize = 0x4804 + 32 - off; // refuses to map addresses that extend beyond the allowed memory range if (vsize psize) { return -EINVAL; } if (remap_pfn_range(vma, vma-vm_start, pfn, vsize, vma-vm_page_prot)) { return -EAGAIN; } vma-vm_ops = simple_remap_vm_ops; simple_vma_open(vma); return 0; } 1. in user space I do it approximately in the following way: . volatile unsigned char* dmt2_regs; dmt2_regs = (unsigned char*) mmap(NULL, 0x1000, PROT_READ|PROT_WRITE, MAP_SHARED, fd, 0); while (true) { uint32_t t0 = * (uint32_t*) ( dmt2_regs + 0x3c ); std::cout t0 std::endl; } -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups BeagleBoard group.

Newbie here ... sorry if too basic or already answered somewhere, I can not find what I'm looking for. Here is my problem: I'm trying to connect my BBB to an android device via bluetooth. I'm using a HC-05 device and followed the instructions in herehttp://hipstercircuits.com/enable-serialuarttty-on-beaglebone-black/. It works to some extent. Bluetooth connects to the devide and I can send messages to my android device runninga terminal software ( BLUETERM). Problem is that I can not read from the device (which BTW is the sole purpose of the connection ...). I'm doing it pretty basic by now, just some echo hello /dev/ttyO4 and cat /dev/ttyO4 The first works, the latter doesn´t. All I'm trying to do by now is to make some sort of simple android app that can turn on and off some LED on the BBB. Later will go more complex but what I need now is to set the foundations to my project. It would be great if there is a tutorial somewhere on how to open a shell over bluetooth from the android device, would be wonderful. I found some on how to do it on rasPi but no luck with BBB Any advice? any tutorials? any help ...?? If I have to be more specific please let me know what you need and I'll give the informion. I'm running trhe latest armstrong distribution n a BBB rev B. Thanks for any help!
