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 ...
Hi ST Team,I am working with STM32MP257F-EV1 board and facing an issue while trying to connect the ST-Link interface using STM32CubeProgrammer.Connection setup:An external ST-LINK/V2 programmer is connected to the CN22 (ST-LINK header) on the STM32MP...
I'm trying to use pwm for backlight control in stm32mp257f-ev1, the same changes shown in below patch is implemented in both u-boot and kernel, i used u-boot pwm commands and it seems working but im getting this deferred probing issue in kernel logs ...
Hi We have a custom board using STM32MP257F and would like to program external NIOR flash using STM Cube programmer over a UART interface.We have the following modified TSV file, where we have modified the first line to use - 0x01 fsbl-boot Binary no...
Hi ST Team,I am working on custom MPU board based on STM32MP257F-EV1 reference design.For our design,reassigned I2C1 from the M33 core to the A35 core using STM32CubeMX.The I2C1 ownership changed from CID2 (M33) to CID1 (A35) in CubeMX.Corresponding ...
I am trying to create custom sd card image for the stm32mp157f-dk2 board. For device tree I used dts files from basic project created by STM32CubeIDE for that board, for now I didn''t do any changes to device tree. I used latest sources from v.25.08....
