zc706 nist_qc2: SPI3 MOSI not working

Ah: I think `P28` should be `R28` here: https://github.com/m-labs/migen/blob/7507a2bb16dd2cac63535175ce67fb30dfdae1c0/migen/build/platforms/zc706.py#L133 See Page 69, Col.…

zc706 satellite can't have boot file reloaded to SD

Oh I see - I was under the impression that the coredevice would try to fetch its bitstream from a server, rather than providing a server that waits until a client supplies the bitstream. Makes sense!

Reiterating that this very low on the priority list, but to summarise my thoughts and how I understand things (which may well be wrong): * Rewriting Kasli gateware remotely is easy via JTAG over…

zc706 networking never comes up if RTIO PLL lock fails
