Hello,I'm working with the STM32MP15 and have found a problem with USART1 during the boot process on a secure boot enabled (TZEN) hardware. The system freezes when U-Boot tries to reset USART1.The problem is with the RCC_APB5RSTSETR register (0x188)....
Setting SIGN_KEY_stm32mp15 leads to an error As described here: https://wiki.st.com/stm32mpu/wiki/How_to_perform_Secure_Boot_from_Distribution_package Set and adapt these variables: echo 'SIGN_KEY = "key/stm32mp15/privateKey.pem" ' >> conf/local.con...
This is how I would like to use rs485:&usart3{
pinctrl-names = "default", "sleep";
pinctrl-0 = <&usart3_pins_mx>;
pinctrl-1 = <&usart3_sleep_pins_mx>;
status = "okay";

Quick update: This issue with my custom STM32MP153C board has been resolved. The solution was to use the clock settings from the ST development kits instead of CubeMX's.
had the same issue today, non-secure-world is not allowed to change that rcc reset register.Please see my post here:Issue with USART1 Reset in U-Boot on STM32MP15 with TZENand just have a look at TRM 10.7.107: "If TZEN = '1', this register can only...
