Can ST please provide a guide for bringing up a custom board without using the STPMIC? We are extremely space constrained and unable to fit the PMIC. For our use case we just want simple LDO's with bucks as required.There is no material I can find th...
We are bringing up a custom board with LPDDR2 and no STPMIC. I have been following the bring up guide and have gotten past disabling I2C4 and fixing the HSE clock issue in the device tree. I have merged in quite a few things from dev kit 'working' de...
I am puzzled with a curious build problem:The recipe gcc-arm-none-eabi-native downloads gcc-arm-none-eabi-10.3-2021.10-x86_64-linux.tar.bz2 but the download finishes to early (at 100MB instead of 150MB). Therefore the checksum check fails.BUT:If I co...
Datasheet says STM32MP15xx has ADC but here seem no ADC.I am not sure if I am missing something.
