There are no signals on pins I2C5 in CM4 mode in the custom device tree.
Hello.I created a custom device tree in CubMH and added its instructions "How to create your own machine" (https://wiki.st.com/stm32mpu/wiki/How_to_create_your_own_machine)I wanted to run I2C5 in production mode. Running my code stops CM4 and CA9, wh...

Resolved! How to use I2C1 in TF-A to control STPMIC1?
In our custom board we are using I2C1 to control and configure STPMIC1. I'd like to use I2C1 in TF-A so PMIC can be configured to power DDR during boot. I2C1 is not supported by default in TF-A, but looks like there is a way to do it as described in...
STM32MP157D DTS v2 simple-bus node not enabling? No UART, MMC, or any other peripherals getting initialized
I'm trying to boot an STM32MP157 using the v5.4-stm32mp branch of ST's Linux kernel, and it doesn't appear that peripherals under the simple-bus node in the DTS file are getting probed. I copied the stm32mp157d-dk1.dts file as a starting point, but s...
U-Boot not starting from SP_MIN on STM32MP151
I am on environment 2.0.0 and a custom board with PMIC and STM32MP151 booting via serial interface with the STM32CubeProgrammer using UART4 for debug output.I managed to get the TF-A running up until it is in BL32 (sp_min) and prints "Preparing exit ...
