Hi!I accedently used STPMIC25A instead of STPMIC25D when I want to boot A35 from SD card.According to AN5727 page 13, topic 4.1.8. it says that if the MP257 is going to boot from SD card, then the STPMIC25D must be used instead of STPMIC25A due to LD...
Hello, Happy new year !I create my custom board with STM32MP153C I try to boot but I have an issue. Starting systemd-udevd version 255.17^ root '/dev/disk/by-partuuid/e91c4e10-16e6-4c0e-bd0e-77becf4a3582' doesn't exist or does not contain a /dev. [ ...
I am trying to connect the STM32MP257F-EV1, following the guide on the wiki. Followed the LInux preparation. At startup, I get a blinking RED LD1 and steady green LED When start the laptop on windows, the device manager shows a DFU device a. But whe...
Problem descriptionI have a custom board based on STM32MP157FAA.The SD card boots perfectly in:ROM bootTF-A BL2 (FSBL)But once control reaches U-Boot, the SD card becomes completely unusable and U-Boot shows continuous: stm32_sdmmc2 mmc@58005000: cm...

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 with an STM32MP151 and I would like to start the Cortex-M4 core as early as possible during the boot sequence.The main requirement is to run a real-time task on the M4 that reads an analog input (ANA0 – ADC channel) with minimal st...
Hi,We're using STM32MP157FAA1 for our products. our kernel version version is 5.15 & dunfell Yocto. Our system requirement is to enable a pwm using lptimer [ PD13 ] that serves even in low power mode. below are our queries:1. As we understood it need...
Dear Sir/Madam, I hope this email finds you well. I am currently designing a custom PCB board based on the STM32MP157FAC1 microprocessor and associated STMicroelectronics components. I would like to kindly request your support in reviewing and verify...
Hello,with my colleagues @LOrci.1 and @Raggio we are testing a SOM based on STM32MP257F line, running OpenSTLinux 6.6. Our SOM is connected to an expansion board originally designed for MP1 SOM by ST (STM32MP157C line).For video output we use the DSI...
