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...
Hello,I successfully used linuxptp with stm32mp257f-dk board, but now need to do the same with stm32mp157f-dk2. linuxptp was built from the same latest sources for both boards using corresponding SDK for each board. But when ptp4l is running on stm32...
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....
Hello! I'm working on bringing up a bare-metal STM32MP133C bare-metal on the dev kit from DIGI, using the HAL layer from ST. The problem I'm running in to is we're getting stuck on HAL_ETH_Init as when we enable the MAC clock, DMAMR's 0 bit (the rese...
Hello community!I am trying to port a firmware for a Seeed Odyssey SOM-based board from Hardknott to Mickledore. This uses meta-st-odyssey and meta-st-stm32mp (openstlinux-6.1-yocto-mickledore-mpu-v24.06.26). I have it booting fine on the development...
