Hi, we would like to change from 24MHz to 8MHz which is available in our stock, I see in device tree, file stm32mp151.dtsiclocks { clk_hse: clk-hse { #clock-cells = <0>; compatible = "fixed-clock"; clock-frequency = <24000000>; }; ...
I am trying to use the 40 pin GPIO, namely pin 48 and pin 40 which are PF11 and PI6. PI6 is assigned to sai2. I've disabled sai2. However, the DTB will not compile because there is still a reference to the sai2 pins here:sound:sound{ compatible = ...
Hello, I bought STM32MP157D-DK1 design kit. But I would like to buy the display board from ST. is it possible?Because I only saw that if you buy the STM32MP157F version.Many thanks,Mauricio
We modified the device tree file corresponding to our development board based on stm32mp157d-ev1.dts.We did not use a PMIC chip, so we added our own power node and modified the default serial port output.This is my device tree file:The following erro...
We want to change default uart from UART4 to UART8,from:aliases { ethernet0 = ðernet0; serial0 = &uart4; .... };we changedserial0 = &uart8;and implement uart8 as below:&uart8 { pinctrl-names = "default", "sleep", "idle"; pinctrl-...

Hi @OlivierK ,I am using openstlinux ecosystem release v3.1.1 and trying to use secure boot feature with yocto and as per https://wiki.st.com/stm32mpu-ecosystem-v3/wiki/TF-A_overview we need to set "TRUSTED_BOARD_BOOT=1".We need use "TF_A_SIGN_ENABL...
On an STM32MP157C the IWDG is setup correctly, but when I trigger an endless loop in U-Boot or a panic in the Kernel, after the timeout the reset does not work. All I know is that the debugger shows a Vector catch. In OPTEE OS the reset works. Is thi...
hi st expertI am porting openstlinux for my robot board, I found that the system froze after uboot selected the extlinux file, and then rebooted after a while，the uart log :Do I have any debugging means to analyze where the current problem is? than...
