I am building a custom Yocto image for STM32MP1 (STM32MP157) using ST OpenSTLinux (dunfell-based) and I am facing a persistent U-Boot build failure.Environment:SoC: STM32MP157 (custom board)Yocto: ST OpenSTLinux (dunfell)U-Boot: v2020.10-stm32mp-r2.2...
Hello,Im having an issue with flashing of OpenSTLinux on STM32MP157F-DK2 ------------------------------------------------------------------- STM32CubeProgrammer v2.21.0 ----------------------------...
Hello!I am in the progress of setting up a Yocto based build for a custom board based on a STM32MP157C. I am using "vanilla" Yocto scarthgap with the respective ST meta layer: https://github.com/STMicroelectronics/meta-st-stm32mp meaning I created a ...
I've inherited a board that is based on an STM32MP135AAE3 and has an external DDR (W63AH6NBVABI, a DRAM 1Gb LPDDR3 from Winbond). It appears I need to create a DDR.h file similar to the stm32mp13xx-ddr3-4Gb.h or stm32mp13xx-ddr3-8Gb.h files that STM...
The project requirement is to use optical ethernet with STM32MP257F. I want to try this interfacing first at STM32MP257F EV1 with some copper to optical Ethernet converter module, but in STM32MP257F EV1, Ethernet pins are not available for interfacin...
Hello Everyonelinux kernel version: 6.6.78After configuring the device tree, I can see the SPI device /dev/spidev6.0 on the STM32MP257F-DK board. However, when I run spidev_test[1], it returns the error message "Invalid argument."I tried using an osc...
Hello, I am using a STM32MP135F on a custom board which is working well using SD Card (sdmmc1).The SDCard is partitioned as: 1) fsbl12) fsbl23) fip4) bootfs5) rootfsFrom the SDcard system, I try to prepare the eMMC (4GB, sdmmc2).I tried different con...
Hello,I am working on a custom board derived from the STM32MP157F-DK2 reference design and currently validating the basic bring-up.I have a few questions specifically related to the Cortex-M4 (MCU) core on STM32MP157F:Checking MCU execution via JTAG/...
Hi,I am trying to work with the USART6 which is connected to is connected to PF13 (TX) and PF14 (RX) on the extended GPIO.It looks like the SCRIF does not allow access to this USART, wven though the OPTEE configuration seems to enable it:from optee/....
I have CubeMX 2.0.0 and I notice that if I want to enable DSIHOST, I need to first enable HSE.But the clock configuration of the DSI does not require HSE. It seems that the clock configuration of DSI seems to work with HSI in CubeMX 2.0.0.So, the que...
