Using printk on an STM32F103C8 board
Scott Nelson <scott@...>
I’m trying to get Zephyr running on an STM32F103C8 "blue pill" board by using the similar nucleo_f103rb board config (with which I can successfully get an LED to blink). I’m trying to setup printk by enabling CONFIG_UART_STM32_PORT_1=y (TX=PA9, RX=PA10) but I get the following compile errors: https://pastebin.com/raaww0a8
Am I missing additional config?
I was also planning on setting CONFIG_UART_CONSOLE_ON_DEV_NAME="UART_1" and CONFIG_PRINTK=y in hopes of being able to read printk messages via a USB-to-serial adapter.
