We have a custom board with and STM32MP153CAA processor and are trying to get it to boot from an SMCC card on SDMMC2 interface. If I loaded the tf and fip files via a UART I am able to get u-boot running and then use the "run bootcmd_mmc0" to boot th...
Hi all,I have been trying to build a custom machine based on STM32MP157C MPU. Right now I am facing a weird issue.Defconfig file is attached. However upon giving build , i cannot see the stm32-crc module , built added and loaded. Is there something w...

I managed to make the M4 WWDOG to work.I got on Linux cmd line:remoteproc remoteproc0: crash detected in m4: type watchdogHow can I catch and handle this events programmatically on a shell script, C or Python ?
Please excuse my ignorance in this matter. We develop a custom board based on STM32MP15f-DK2. We would like to use Segger's J-link devices for initial codeloads.I understand that mmc/sd card are not memory-mapped flash types, so j-link will not work ...
we are using M28W320ECT 3V Supply Flash Memory for more than 10 years wo any problems in our MCU units now, suddenly in new production this part is gone defect several times- drawing current on the 12V programming Voltage Input, no read /write opera...
