Why not. After all, the IMU is currently 'solder-on' so we can try different ones without changing the entire design.
With a little trick (connecting the solder-on boards with small pins) they can also be easily swapped.
All that is required is a tiny PCB with the proper connections.

The problem is simple:

  • SATA requires 3+ Gbit to be useful, i.e. we would need MGTs to handle that.

What happens is that the GEM is initialized with the u-boot hard coded MAC address, and changing the etheraddr later in uEnv.txt does indeed change the u-boot generated packets, but it doesn't update (or reinitialize) the GEM, so it still only receives packets for the hardcoded MAC.
