Hi,
I apparently loaded a bad bistream onto my e320 (in case) and now it
seems bricked. I am trying to use the jtag programmer on vivado 2019.1
-> digilent onboard jtag programmer -> reprogram the fpga.
Unfortunately the stm32 turns off the zynq as quickly as it comes up,
is there a way to override this behavior? I can’t connect long enough
to program the fpga…

Thanks for any suggestions- Mike
Unless I'm mistaken, the FPGA image on the E320 comes from the Linux
filesystem on the system image. Just make yourself a fresh system
image uSD card, and your
system should come up.
