@MrKevinWeiss @maribu From my point of view, the PR should not affect ESP32. `ets_printf` as well as `stdio_uart` are using `UART_DEV(0)` which is already initialized by the bootloader. The system initalization function only sets the baudrate to configured `STDIO_UART_BAUDRATE`: https://github.com/RIOT-OS/RIOT/blob/6037fa2536b1b2267f175b614e3074baeb35cc30/cpu/esp32/startup.c#L257-L261
Function `uart_init` which is called during `stdio_init` has no affect for `UART_DEV(0)`. The `uart_init` function only initializes the UART interfaces `UART_DEV(1)` or `UART_DEV(2)`.
