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>; ...

Helllo i configurated my Device tree so i a can use my USART3 as a serdev. But when i run "cat /proc/tty/driver/stm32-usart". i can see my serial port but my RTS pin is missing. I configurated my device tree like this:&usart3 { pinctrl-names = "defau...

Hello on my serdev when i set it up the transmition complete is not set:stm32-usart 4000f000.serial: transmission complete not setI configurated my device tree like this:&usart3 { compatible = "st,stm32-uart", "st,stm32f7-uart", "st,stm32h7-uart";...

Hello on my kernel module my probe funtion gets not called.static const struct of_device_id stm32_match[] = { { .compatible = "st,stm32-uart", .data = &stm32f4_info}, { .compatible = "st,stm32f7-uart", .data = &stm32f7_info}, { .compatible = "st,stm3...
