Boot up a SAMD51 / SAME54 w/o ASF


Recommended Posts

8-Bit controllers are very "honest" controllers, aren't they? No bus matrix, fixed interrupt latencies, no clock domain crossings.. one clock for everything. Home sweet home!

But everyone has to learn new tricks, so I decided to try a jump into the deep end and booted a 32-bit SAM device from scratch. The challenge of these (former Atmel) devices is, that only framework solutions exist. Even the app notes are written in ASF framework, no one will tell you how to set things up in bare metal.

So here it is, my first 32-bit and first Github project: https://github.com/dxstp/same54_init

Have fun! 😎
