Hey.

I do believe that’ll require some additional coding.
Please take a look at Kernel.cpp

Cheers.

Hi:
Thanks for your answer,but uart1 don’t work when i add"#define uart1_checksum CHECKSUM(“uart1”)"in the kernel.cpp. while,uart1 could be used Only change “USBTX = P0_15, USBRX = P0_16,” in the PinNames.h .
So ,if i want to use uart1,should i must write additional code like uart0 ???

Yes, getting UART1 to work in addition to UART0, is going to require a bit of coding.
