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.
We can use devmem to read/write all gpio port registers except for portZ.We know this port relates to secure. is there any way to remove secure feature on this port so we can use devmem on this port?Thanks

Hey,I was able to successfully flash the Starter Package following this article and after building the OpenSTLinux distribution following this, I'm having trouble with flashing it. After completeing the build process, inside the flashlayout_st-image-...
I'm using a custom stm32mp157a board with a DSI display.If I enable uart8 using pins J8 (UART8_TX) and J9 (UART8_RX) the display driver (panel-sitronix-st7701.c) doesnt load properly and the display stays blank. uart8 does work properly. If I disab...
We recently udated from OpenSTLinux v2.1 to v4.1. The boot chain is solid, but occasionally we are getting TEE aborts (trace listed below). I am not sure exactly how to debug this, any help would be appreciated. E/TC:1 E/TC:1 Core data-abort a...
