Hi all, I tried both passing console=ttyJ0 and using CONFIG_SERIAL_DCC_STDSERIAL in order to force printk's going to ttyS0 to go via JTAG DCC but no success. I can see that tty_write() calls directly uart_write(), and not dcc_console_write(). I am suspecting that my UART port is not working correctly, so I want to use JTAG DCC instead. How to force tty_write() to call JTAG DCC routines ? Did anyone had success with redirectiong std serial to JTAG DCC ?
