It's start from 699cc4dfd140 ("tty: serial: imx: add imx earlycon driver"), the driver uses the uart_console_write(), but SERIAL_CORE_CONSOLE is not selected, so uart_console_write is not defined, then we get the error. > > thanks, > > greg k-h > . ^ permalink raw reply [flat|nested] 4+ messages in thread
