STATUS
======
Testing has just begun. So the status is code-complete but only
partially tested.
2014-10-28. Testing is still in progress. At this point all basic boot
operations are successful: The LEDs work and the application tasks appear
to be successfully started. LED2 is on and LED0 is glowing (meaning that
interrupts are being processed). However, I get no output on PE0. Data
appears to be sent (at least by efm32_lowputc()). However, no signal
activity is present on PE0.
I am, of course, thinking that this is a pin configuration issue.
