Hi,I have few custom boards with STM32MP257 mostly running PTP related tasks. Once in a while (once in a few days of continuous run) I have noticed the following error in the dmesg (as it seems UART related - I have 4 UARTs enabled in the DT, while 3...
Hi im working on stm32mp257f-ev1 and the "edt,etml0700z9ndha" display,Im unable to decode the logic why the back-light enable gpio only gets high when there is a display connected in the lvds port, what logic is used to detect the lvds display connec...
Hi Team,I am using the following method to enable password protection for both SSH and serial login.I added the below configuration in local.conf:INHERIT += "extrausers" EXTRA_USERS_PARAMS += "\ usermod -U root; \ usermod -p '\$6\$ao/KaHyZbsg...
According this article: https://wiki.st.com/stm32mpu/wiki/GPU_internal_peripheral. It is not supported configuration for OpenSTLinux BSP. Can I manually assign or enable GPU with the x-linux-qt image? If yes, how?
I opened a PR on https://github.com/STMicroelectronics/u-boot.git for a patch that is applicable only downstream, and since I did not receive any response, I contacted Patrice Chotard, who told me to contact you for submitting downstream patches.In a...
Hello.Is there any way to exclude some GPIOs from Linux, when I control them from M4 core and I don't want to give an ability to control them from Linux apps? I would like to exclude e.g. PG12. I tried this, which should be exactly for such use:&gpio...
Hi,Could you share documentation or examples for running quantized foundational models (e.g. Google Gemma) on the STM32MP257F-DK—first in Python, then in C/C++ using the STM32MP2 NPU? Specifically:Does the STM32MP2 NPU support transformer-based archi...
Dear Team,We are trying boot Uboot(V2025.04) on a Custom board with STM32MP157AAA3 Processor.But while booting we can see that code hangs at WDT: started Watchdog@5a002000 with servicing every 1000ms (32s timeout) and restart after sometime.We have a...
Hi everyone,we applied the ST FWU reference solution on our own platform based on the STM32MP157F.The solution was taken and adapted from the ST Yocto layer meta-st-ota (https://github.com/PRG-MPU-CUST/meta-st-ota). SummaryWhen performing consecutive...
Hello We are implementing the memory CRC generation sequence as described in the reference manual. According to the documented procedure, the following steps must be executed:1. Write 0x0 in CRCC[1:0] of RAMCFG_xCCR1 to deactivate the CRC.2. Write 1 ...
