Hi,

Can you install Tera Term or use the UART console that comes with CCS.

Hi Wang,

It seems you have 4 UART (13, 14, 15 and 16) connections, can you try each of them and see if output comes on any one of the UART terminal?

Regards,

Brijesh

Hi Brijesh/Wang,

UART prints will come on port 16. Other UART settings like data bit, parity, stop bit should also be set to 8 N 1.

Hi wang,

I have not really tried using Mobaterm, could you please check in teraterm?
Btw, have you flashed sbl and AppImage on the board? If not, could you please try flashing them as explained in the userguide?
