Hi,I am trying to use USART6 on STM32MP257F-DK development board. I have enabled it in the device tree, recompiled it and I now can see the /dev/ttySTM1 node. The problem is, that sometimes, after reboot, any access to the USART (even changing its ba...
Hi ST community,We are bringing up a brand-new custom board based on STM32MP131C (Rev.Y) and are facing an issue while flashing SPI-NAND over USB DFU.Boot statusTF-A (BL2/BL31) boots correctlyOP-TEE OS boots and hands off to normal worldU-Boot starts...
Hello ST, We are trying to enable USART6 as a serial console, in the stm32mp257f-dk board, we have builded the SDK using Openstlinux "Distribution package", I had done the below changes in the stm32mp257f-dk.dts device tree present in the kernel...
Hello,I am facing an issue with DFU mode on an STM32MP157C when Secure Boot is enabled (OTP locked) and SCMI is active via OP-TEE, and I would like to confirm whether this is an expected behavior or a known limitation.I am using STM32CubeProgrammer t...
I'm working on a custom stm32mp133d board and Yocto (latest release), but something has me quite puzzled.Our hardware looks like this:- Kingston EMMC04G-MT32-01G10 (mmc2)- 4Gb DDR- STM32MP133d- STM32PMIC1most of it is very similar to STM32MP135F-DK. ...
Dear All,I am trying to minimize the u-boot and started to remove some features I don't need.I tried to remove whole video & LCD support, but run into issue that stm32mp1.c has a large patch, that applies LCD automatic recognition and extern referenc...
