I tried to enable both UARTs on JN5168 chip and redirect printf output to UART1. I changed the putc function in:
https://github.com/contiki-os/contiki/blob/master/platform/jn516x/lib/slip.c#L442
to use uart1_writeb. I also enabled the UART1 in:
https://github.com/contiki-os/contiki/blob/master/platform/jn516x/Makefile.jn516x#L74
and added the uart1_init in contiki-jn516x-main.c. However the Contiki makes a BUS EXCEPTION during boot, because of that line:
https://github.com/contiki-os/contiki/blob/master/platform/jn516x/dev/uart-driver.c#L164
The printf should be changed to DBG_vPrintf
