[SOLVED] USART_QUICK_START (polled) w/stdio does not work

Sat Feb 15, 2014 7:24 pm

I am trying to get the quick-start example for the polled usart to work as the stdio device so that 'printf' will send data to the virtual com port in the EDBG module on the SAMD20 Xplained Pro. The stock example works perfectly; however, when I make the recommended modifications to qs_usart_basic_use.c and add the stdio drivers, I get garbage on my terminal screen. I will attach the modified source code. Any help is greatly appreciated.

This problem went away with an update to AS6.2. Apparently there was a bug in the embedded debugger firmware.

Return to “SAM D20 Cortex-M0+ MCU”
