What is the capacitance IO of HSE and LSE?
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...
