Re: What does the GPIO use for a bootloader?
Everything seems to be working as advertised and I now have a downloader that can program my 64k part, using a flat memory map from 4000 to F780, in one fell swoop.

Re: Board bringup procedure
I read that the GPIO board used the same upload mechanism as the Megasquirt.
It actually uses the same mechanism as the MSII
The bootloader has no UI, it does not talk to people. So don't type anything into it and expect an ...

So where is the boot loader code?
Or is that not for public consumption?
Matt I sent ...

I have a P&E ...
