Hello,I can't use the "ums" command via terminalprog (minicom)Message is always"STM32MP> ums 0 mmc 0UMS: LUN 0, dev 0, hwpart 0, sector 0x0, count 0x1dacc00Please connect USB cable. "After 60 seconds: "USB cable not detected. Command exit."Communicat...
HiIn my project the root filesystem is read-only, so I need to have a writeable partition mounted on /home. I first tried doing this in my machine conf (conf/machine/stm32mp1-raichu.conf) with the following lines:ST_VENDORFS = "0" ST_USERFS = "1" S...
Hello, I have a question.What are some ways to control GPIO from python?I want to do that with a starter package.Best Regards!
We use the STM32MP157CA and the STM32CubeIDE and let the code generator generate a confiuration with the required modules. In our case the SPI1 on the pins (PZ0,PZ1,PZ2). The generated functions provide the initializations for the SPI1. Unfortunately...

Hello on my serdev when i set it up the transmition complete is not set:stm32-usart 4000f000.serial: transmission complete not setI configurated my device tree like this:&usart3 { compatible = "st,stm32-uart", "st,stm32f7-uart", "st,stm32h7-uart";...
Hello, my EVB is based on STM32MP151A SoC. The situation we are facing is that sometimes, the FSBL gets stuck and we would like to recover from it. i.e. reflash some Known Good FSBL. As the FSBL in that situation is kinda functional, the device wil...
I need some clock synchronization between M4 and A7 cores. So I need steady clock values from A7 and M4 for single time point
Hi, everyone. :)I am planning to make communication system with stm MCU.AND, at the same time, I should boot up 'Linux' OS on stm MCU, for matching with other systems.I'm just wondering that stm MCU can carry on Linus OS.If stm MCU can use Linux OS, ...
While learning how eMMC partitioning works, I issued a mmc create gp command from Linux and since then I cannot flash a new image on a EV1 board. The error message I get is:Message from Embedded Flash Loader : ssbl (0x6): invalid address 0x80000 (min...
