Hello,
I am trying to get our kernel to boot on our custom hardware. I had built this kernel for BBB with different hardware and it worked. Im not sure what it is either looking for and not finding or where to start looking.
Any help would be appreciated!
I have attached the terminal print out. We have 128MiB ram, no RTC

Part Number: EVMK2H
I am trying to update the UBOOT and Linux on an EVMK2HX module (stored in flash) to the pre-built files in the current version (06_00_00_07) and then upgrade the 2 GB EVMK2HX memory module to an 8 GB one. There appear to be a number of ways to do this, which seem to be somewhat inconsistent( to a newbie).
2. Can the module be rebooted to see if the UBOOT load was successful, or should the Linux image be loaded prior to rebooting?
3. The 06_00_00_07 SDK Getting Started Guide section 1.1.4.2 indicates that the Linux image is written as a single ubi file(named tisdk-server-rootfs-image-k2h-evm.ubi), however a single tar.xz file is provided instead. How is that file converted into a ubi file that can be downloaded?
4. The following steps for downloading the 06_00_00_07 SDK provided Linux ubi file were gleaned from section 3.4 and section 3.3.6 question 3:
c. Test the changes by typing:
5. If the EVMK2HX module does not boot after the above, what is the recovery mechanism? … Use the UART and BMC mechanism described by board-support/u-boot-2019 … /board/ti/ks2_evm/README
Just trying to make sure the steps are correct and a recovery path is known.
Thanks,

Hi
I want to update the qtlibs in matrix-rootfs to qt5.11.3 under the SDK of ti-processor-sdk-linux-am437x-evm-06.00.00.07.

Hello, I have a problem when loading a c++ program to PRU,syslog is as below.
Background:have to mention that I have using the c program(using rpmsg)on Pru for nearly two years.Now I am rewriting the program with c++,I suppose this problem is related to stack size issue,but I can not comfirm it
I want to know why this happened,and more importantly , I want to know how to debug this problem more efficiently( I have tried to modify my problem to debug the problem,but every time when it occured ,I have to reboot the whole develop board,which is quite inconvenient and annoying )

I have a custom DSP board with only a C6748 with external SPI FLASH and no DDR or OMAP. When I attempt to erase or program the SPI flash with the sfh_OMAP-L138 utility, it stalls waiting for SFT. What do I need to change in the utilities to make this work? I have downloaded and installed all of the tools and can successfully rebuild all of the utility files.
Part Number: AM4372
Hello,
What is the recommended way to manufacture AM4372 based product with eMMC storage?
I am specifically looking for suggestions or materials to program eMMC (in circuit) using boot ROM of AM4372.
Unable to determine the external source, which could run custom SPL / UBoot.
Ideally, it would be great, if AM4372 could boot as per this order,
1) Ethernet
2) USB Mass storage
3) MicroSD (MMC1)
4) eMMC (MMC2)
Many of the existing materials points to variety of boot options using SYSBOOT pins.
However, I am not sure whether those combinations were ever tested on the EVK.
It looks like micro SD seems to be the only reliable boot option.
This may not be possible with our end product.
Looking forward for external boot options with AM4372 boot ROM,
Thanks

Hi all,
I have some usecase with different links. Some of them are running on RTOS (IPU2, DPS, EVE) and some of them on Linux (A15). So, after few hours, Linux just hangs, terminal is not responsive, but camera is still working (IPU core). I read on some post on forum that VSDK IPC method and Linux message que method can not co-exist. It is related to rpmsg driver. So, can you confirm that this is correct and it could be cause of this problem.
Best regards,
Stefan.

Hello,
I'm going to boot my beagle bone black (Version C) platrorm with profibus master application form SD Card. I did the following steps:
1) I rebuilt PDK pakages using
gmake all
2) I renamed "C:\ti\pdk_am335x_1_0_7\packages\ti\starterware\binary\bootloader\bin\am335x-evm\gcc\bootloader_boot_mmcsd_a8host_release_ti.bin" into MLO
3) I built profibus master application with the following properties:
4) I converted "C:\ti\PRU-ICSS-Profibus_Master_01.00.01.00\protocols\profibus_master\projects\profibus_master_AM335x_arm\AM335x_release\profibus_master_AM335x_arm.bin" into
"C:\ti\PRU-ICSS-Profibus_Master_01.00.01.00\protocols\profibus_master\projects\profibus_master_AM335x_arm\AM335x_release\profibus_master_AM335x_arm_ti.bin" using the following command
>> tiimage.exe 0x80000000 NONE "C:\ti\PRU-ICSS-Profibus_Master_01.00.01.00\protocols\profibus_master\projects\profibus_master_AM335x_arm\AM335x_release\profibus_master_AM335x_arm.bin" "C:\ti\PRU-ICSS-Profibus_Master_01.00.01.00\protocols\profibus_master\projects\profibus_master_AM335x_arm\AM335x_release\profibus_master_AM335x_arm_ti.bin"
5) I renamed "_ti.bin" file to "app"
6) I created SD card bootable using Win32DiskImager and prebuilt-sdcards image file
7) I copied and pasted "app" and "MLO" files generated by myself into the bootabled SD card
8) I inserted SD card into my beagle bone black and I powered it on while I was pressing S2 button
9) I saw the following output messages on the terminal:
As you can see, the booting prusedure stopped at "Jumping to StarterWare Application ..."
I searched about the above error and I found some solutions, but unfortunately those solutions did not work for me.
What should I do? What are my misstakes?
Thanks for your attention,

Hi,
I've leveraged the quickStartOMAPL1x_rCSL project and implemented the DSP side code sharing memory at SHARED_CPU_VARS_MEM 0x8001FC00 (sharedCpuVars.h).
At the ARM side I run Linux user space utility that mmaps this shared memory, reads and writes data.
The issue is that this utility successfully reads data, but cannot write. My guess is that there is no coherency between the sides. I don't see any section defined for SHARED_CPU_VARS_MEM in quickStartOMAPL1x_rCSL examples.
What are the solutions for this issue? Is there a way to flush/invalidate cache from user space?
Below is the user space code I run.
Thanks,
Aviv

Hi,
From the keystone Hardware guide, it is mentioned that unused LVDS clock can be terminated.
So is that the same case with DDRCLK ? I am not using DDR for processor .
Datasheet Pg 73 Power sequencing shows the DDRCLK . Does the DDRCLK required for intial boot up or it can be left terminated as per LVDS unused recommendation?
Please clarify

I have an issue currently
I have a custom board designed with AM5726 and it is running correctly with SDK3
But with changes required and DSP options SDK4 / 5 abd Now 6 is required for DSP functions
We have started to get the SDK5 compiled and working with all requirements on our Board
One thing we are noticing is that after a day or two running the OS the following starts to happen
"
[ 10.357803] gpio-51 (sysfs): gpiod_request: status -16
[ 10.357808] export_store: status -16

[ 10.358133] gpio-57 (sysfs): gpiod_request: status -16
[ 10.358137] export_store: status -16
"
This is a small extract and it seems the DTS or something gets corrupted or chanced which then delinks the GPIO's from the sysfs... But at this stage I am a bit lost
Any assistance would be appreciated

Hello,
I had requested for support files for tftp booting of AM335x processor in the TI e2e forums some time back in this form post:
e2e.ti.com/.../679231
I was contacted by TI on private message and a tiny filesystem and flasher script was shared with me.
The file name of the tiny filesystem shared with me was "am335x_tiny_filesystem.tar.gz"
These files had worked for us. But as a part of process, we are required to have the source files used to generate this filesystem and also be able to regenerate the filesystem.
I understand that the filesystem was generated using yocto project and that the bitbake recipe used to create the filesystem can be used by us to generate the image on our side.
Please correct me if this understanding of mine is incorrect.
(The SDK we are using is "ti-processor-sdk-linux-am335x-evm-04.02.00.09-Linux".)
So, could you please help me by sharing the files necessary to generate this image?
Thank you in advance

Hi,
I am using the ADAS startup kit named D3-3P-TDA3X-SK (https://www.ti.com/tool/D3-3P-TDA3X-SK). I understand the SoC in this platform is TI TDA3x.
I have downloaded and installed the Vision SDK (version: 3.7.0) in my Linux machine (Ubuntu 16.04; x86_64 machine) from the url: http://software-dl.ti.com/processor-sdk-vision/esd/TDAx/vision-sdk/latest/index_FDS.html (http://software-dl.ti.com/processor-sdk-vision/esd/TDAx/vision-sdk/latest//exports/PROCESSOR_SDK_VISION_03_07_00_00_setuplinux.bin).
I want to build the target OS as Linux (to flash on the TI TDA3x SoC). For this I kept MAKECONFIG?=tda3xx_evm_linux_all in the file Rules.make. Then I followed below steps (from VisionSDK_Linux_UserGuide.pdf):
1. Cloned all the source code (Including u-boot, Linux, sgx drivers etc.)
2. make linux (it got succeeded)
3. make linux_install (it also got succeeded)
4. make -s -j depend (it also got succeeded)
5. make -s -j (it got failed)
From the file (vision_sdk/apps/configs/tda2xx_evm_linux_all/cfg.mk), I could understand that Linux is not supported (Only BIOS is supported)
# A15_TARGET_OS support
# Platform -BIOS -Linux
#
# TDA2XX_EVM -yes -yes
# TDA3XX_EVM -yes -No
# TDA2EX_EVM -yes -yes
So can any one confirm if there is any Linux port available for this platform (so that I can flash Linux instead of BIOS in this platform).
Thanks,
Ameer.
