Exporting a START based project for someone else... I think I see what's causing the trouble, but I don't understand why, nor what the fix is.
AS7 needs to see a directory named .atmelstart, containing:
.atmelstart/...
Should I use Arduino or ASF4... David:
other libraries will let you use SPI1, SPI2, SPI3, ... i.e. different SERCOM pins.
Are there well-known libraries for that, or do I need to write my own? (I'm...

Should I use Arduino or ASF4... @david.prentice (and anyone else):
Here's a concrete question that's probably easy to answer by anyone who knows the Arduino ecosystem:
The Arduino SD library (https...

Configuring SAMD21 for 48MHz Okay - figured it all out. What happened was I was making one change at a time, which masked the fact that there were two problems.
The winning recipe is to use the...

Configuring SAMD21 for 48MHz Small update:
I reconfigured the system to use the 32KHz High Accuracy Internal Oscillator (OSC32K) and the system comes up normally.

Touche: I've started to go down the path of using the code from Arduino-land. But it would seem reasonable that *someone* has (for example) connected an IO1...
