[quote user="Patrick_W"]The schematic shows VCCQ connected to 1.8v. However the eMMC_DAT/CLK/CMD pins are pulled up to 3.3v and Vddshv11 is connected to 3.3v. Should all of these voltages match?[/quote] I am not able to understand this question. Can you provide more details regarding what exactly you need to know for 1.8V/3.3V configuration? Regards, Pavel

Part Number: AM3352 Tool/software: Linux Hi, We have developed a custom board with AM3352 Processor. Sometimes it causes RCU self-detected stall while communicating with Windows PC board via TCP/IP. Any helps or advises are appreciated. Thank you in advance. [Environment] AM3352 SDK version 3.0.0.4, Linux Kernel 4.4.12 (with edma backported from kernel 4.13.4 to avoid a bug) Almost all configurations are default settings. The only difference is removal of unnecessary drivers. [Problem] TCP/IP connection is infrequently disconnected and terminal of our Linux board shows the following message. And the terminal stops. No response to any keyboard input. > INFO: rcu_preempt self-detected stall on cpu 0 The problem has been happened several times, and thread name shown in terminal with above message is different every time. Once it was a SWAPPER. Sometimes the problem recovers automatically in about 3 minutes, and sometimes not. "Recover" means that every function start working again, including TCP/IP communication. It seems that scheduler of Linux Kernel went wrong when the problem did not recover. Some active threads seem not be able to get any CPU time. Login to the board via telnet or ssh is successful while the problem is repdoduced. However, CPU load of any thread or process is 0% according to "top" command. See the following log to know more details.

Tool/software: Starterware Hello, I trying to test a first application with the RTOS for Beaglebone Black with StarterWare 02.00.01.01 for AM335x Sitara processors from Linux and I am unable to run a first test. I merged the Beaglebone Black patch's folder files into the StarterWare's folder and now I would like to run the first test application. The Quick Start Guide (also available as PDF doc) redirects to this tutorial in order to make the SD, referring to the tool HP USB Disk Storage Format Tool v2.0.6 Portable . It doesn't refer to Linux, so I formatted the SD with the following script: #/bin/sh DEV=$1 { echo ',200,b' echo ',,83' echo ; } | sfdisk ${DEV} -uM --force # make FAT partition mkdosfs -I ${DEV}1 -F 32 -n BOOT #make ext4 partition mkfs.ext4 ${DEV}2 -L rootfs Then following the instructions for the Quick Start Guide: The bootloader binary image (boot.bin) appended with the TI Image Header at the beginning is named as MLO. This is available at "\binary\armv7a\cgt_ccs\am335x\beaglebone\bootloader\Release_MMCSD\". The demo application image (demo.bin) appended with the TI Image Header at the beginning is named as 'app'. This is available at "\binary\armv7a\cgt_ccs\am335x\beaglebone\demo\Release\ I copied the contents of \binary\armv7a\cgt_ccs\am335x\beaglebone\bootloader\Release_MMCSD into the BOOT partition, and the contents of \binary\armv7a\cgt_ccs\am335x\beaglebone\demo\Release\ into the rootfs partition and into the BOOT partition as well. However, after putting the SD and turning on the board, I can't see anything on the UART debug console. So what I am doing wrong ? Could you please help to solve this issue ? Thank you in advance. Regards, Simon

I have more informations that could be useful: The adapter I used (let's call it a0) integrates a HUB. I realized that the issue did not occur at all using an adapter that did not use integrated HUB (a1). If the adapter a0 is plugged on a external HUB, the issue starts occuring. I tried to lower to full-speed rather than high-speed, and it didn't help.

Part Number: AM5718 Tool/software: Linux Howdy, On a custom board with a Sitara AM57X, I obtain, from the board's /var/log/messages, this following error: "user.err kernel: [ 234.723032] edma 43300000.edma: dma_ccerr_handler: Error interrupt without error event!". This error happens when I run a OpenCL example provided by the ti-processor-sdk-linux-rt-am57xx-evm-03.02.00.05-Linux-x86 simultaneously with a UART data exchange. In same time when the error occurs, I observe UART console definitively freezing, it is still possible to connect to the board with a ssh console. I have investigated on this. In the source code, the error comes from kernel-source/drivers/dma/edma.c : static irqreturn_t dma_ccerr_handler(int irq, void *data). By instrumentation in this code source, now I know this error is generated by the "edma3_ccerrint" interrupt. But I don't not why. I have read some part çof the datasheet, but I find nothing to start a trace. Since this point, I'm blocked. Have you some ideas to solve this error or improve knowlegdes about it?

Thanks for your advice. I was trying to build my char device LKM module (basic dev that sendds string to kernel and the kernel sends it back to user space using copy to/from user) which worked under Debian. Under the SDK it had problem with copy_to_user(); function. I have got some internal error : 81b PREEMPT ARM. Maybe there are huge diffrence between SDK and Debian that I don't know, so were should I go to learn how to develop my beaglebone under the SDK. I know how to load up the SDK but I can't find any tutorials on how to develop under SDK.

Hi Pavel, Thank you very much for the reply. I have been trying all the above links, the user space script is not working for me. I have written a DM timer driver by referring to one of the above links, and I modified my DTS file. Below are the my pin-mux and timer nodes, /* timer 7 as on E18 */ timer7_pins_default: timer7_pins_default { pinctrl-single,pins = ; }; &timer7 { status = "okay"; pinctrl-names = "default"; pinctrl-0 = ; }; am33xx-test_module_timer { compatible = "test,am33xx-test_module_timer"; status = "okay"; pinctrl-names = "default"; pinctrl-0 = ; DMtimer = ; //reg = ; //interrupts = ; //ti,hwmods = "timer7"; //ti,timer-pwm; }; After compiling and rebuilding the kernel I get the below error in the kernel log, root@am335x-evm:~# dmesg | grep timer [ 0.000000] OMAP clockevent source: timer2 at 24000000 Hz [ 0.000045] clocksource: timer1: mask: 0xffffffff max_cycles: 0xffffffff, max_idle_ns: 79635851949 ns [ 0.000057] OMAP clocksource: timer1 at 24000000 Hz [ 0.249073] clocksource: Switched to clocksource timer1 [ 0.267731] omap_timer 4804a000.timer: could not find pctldev for node /ocp/l4_wkup@44c00000/scm@210000/pinmux@800/timer7_pins_dee [ 0.289424] test_module_timer: probe of am33xx-test_module_timer failed with error -1 Also I have attached my timer driver file please refer it, suggest me If anything needs to be added.(Please visit the site to view this file)

Hello Hi I updated to SDK 4.1. Bridging between eth0 and eth2 is now working. However between eth0 and hsr0 (made from eth2 and eth3) is NOT working. Setup: - PC attached to eth0, 192.168.0.3 - PC attached to eth2/3 via Redbox, 192.168.0.4 - IDK5728 Test result: Pinging between PCs does not work! However I can ping PCs from Sitara and I can ping bridge address from PC.

Christian, The issue needs deeper investigation with PSDK team but seems still there is some limitation. BR Tsvetolin Shulev

Hi user5132856, Could you check whether the issue appears with the last Processor SDK v04.01 available at: www.ti.com/.../processor-sdk-am335x because there is many changes and patches. BR Tsvetolin Shulev

Part Number: LMX2492EVM Tool/software: Linux Hi all, I will possibly work with an LMX2492EVM evaluation board in my lab and the point is that the board will be used in a system which contains some other devices which are configured by a software coded in C++. Are there libraries available under Linux, or something like an SDK, to load a specific configuration into such a device? Thanks in advance, Paul

Rafal, The Software Developer's Guide provides instructions on how to setup up your Linux development environment, install the SDK and start your development. It also includes User's Guides for various Example Applications and Code Composer Studio. processors.wiki.ti.com/.../Processor_SDK_Linux_Software_Developer’s_Guide Check also the below links: processors.wiki.ti.com/.../Processor_SDK_Linux_Getting_Started_Guide training.ti.com/sitara™-arm®-processors-boot-camp-hands-sitara-linux-sdk training.ti.com/sitara™-arm®-processors-boot-camp-building-blocks-pru-development-4-part-series www.ti.com/.../beaglebk www.ti.com/.../support - Training & events Regards, Pavel

Note also that AM335x SK (StarterKit) comes with 256MB DDR3 memory, you can check its device tree file and linux kernel config to get the proper settings for 256MB memory map. www.ti.com/.../tmdssk3358
