project uart_pac10040 loopback

[windychicago]

Dear Sir/Madam

I used sample project uart_pac10040 loopback. It works with not define ENABLE_LOOPBACK_TEST. However, if define ENABLE_LOOPBACK_TEST, and wire the  pin RX_PIN_NUMBER  8 with TX_PIN_NUMBER  6 on the board, it fails and stays at show_error(void).  Note: if I don't use a wire to connect P0.8 and P0.9, it shows the same.

Thanks

correction:  typo P0.9 should be P0.06 and P0.8 should be P0.08

Hi,

You have to have a terminal open while you run the example, else the buffer will fill up and an error will be thrown. Try resetting the application with Termite/PuTTY open and see if it still asserts. 

else:

Which SDK version are you using? Is the example completely unmodified? I just tried the example and can verify that it works with loopback. Have you tried changing the wire? 

regards
