I seem to have bricked my CMOD-A7 while programming the flash.
The 'DONE' LED never lights, and the USB JTAG seems to appear for a few seconds then go away again:

Not sure what I did wrong, but I suspect I failed to set "Under Configuration Modes, select Master SPI x4"
Putting a scope on the QSPI flash, I can see the FPGA attempt to read the image.

I seem to have bricked my CMOD-A7 while programming the flash.

Any hints on how to unbrick?
Thanks
