Closed ric96 closed 4 years ago

ric96 commented 4 years ago

I have a REVC Arty735T with a 25q125a Flash...

The flash process seems to proceed fine:

Booting the kernel images from the SPI flash is indeed currently broken due to changes in flashboot in LiteX and needs to be fixed. Can you try booting using from Ethernet or UART while things are broken? I'll try to fix that soon.
