Hello i wanted to use the GPIOLib to control my pin manualy. so i added this in my device tree.&usart3 { pinctrl-names = "default", "sleep", "idle"; pinctrl-0 = <&usart3_pins_c>; pinctrl-1 = <&usart3_sleep_pins_c>; pinctrl-2 = <&usart3_idle_pins_c>; ...
I work on Win10. DFU is seen in the settings. I use the programmer to transfer the linux image to the customer MP1 board. The transfer is very instable and break on different files/positions. Very seldom the complete *.tsv image is transfered and I c...
I've noticed when booting one of our board designs with a STM32MP157C in openstlinux-5.4-dunfell-mp1-20-11-12 with Weston Wayland under the STM32MP157-Ecosystem-v2.1.0 that multiple times when the kernel is loading I'll see the following messages out...
