Using STM32MP157 with OpenAmp echo example ttyRPMSG0 is missing - sometimes - why ?
I am new to STM32 boards and IDE but have an STM32MP157A-DK1 board which came with an SD Card / OS on it. We want to make our own OS image using the ST linux.In the downloads accompanying the workshop videos we have the DK2_TIMER1_OpenAmp_Solution to...
STM32MP157A ethernet MAC address not setting?
Hi,We are using stm32mp157a processor in my custom board. I need to change MAC address because in uboot log it is showing it is showing invalid MAC address. I am setting MAC address using setenv ethaddr 11:22:33: 44:55:66 command. But when i set etha...
Errors on building the Linux® kernel source code
Hi, I got the result as below while I was building kernel images (uImage and vmlinux) and device tree (dtbs). Can anyone help me fix it?$ make ARCH=arm uImage vmlinux dtbs LOADADDR=0xC2000040 GEN Makefile CALL /home/rickweng/STM32MPU_workspace/STM...
We are building a board based on ST32mp157c and have problems enabling USB port 1. We did not include the ECMF02-2AMX6 choke. Could this be the problem?
We have also deleted the OTG (USBC) hardware and have commented out the code to check for the OTG power., Otherwise we are using the basic defconfig and the DK2 devtree.

initilize ttyRPMSG0 and ttyRPMSG1
Hello!I am trying to replicate the workshop STM32MP1 - 11 Inter-Processor Communication Lab Example. I create a new STM32 project and copy all the data from the lab example. Then I connect the device (STM32MP157C-DK2) but the /dev/ttyRPMSG0 does not ...
Changing the I2C bus the PMIC is connected to in STM32DDRFW-UTIL
We quite recently learnt of the move from U-Boot SPL to STM32DDRFW-UTIL and that the MX too would not longer work with the former. That wasted a decent amount of time.The problem is although the code for STM32DDRFW-UTIL is available our PMIC is on I2...
