Hi,
We bought 2 UltraZed-EVs with carrier cards, but one of them was dead on arrival. It does not boot like the other one in any boot mode. However, I can hook it up to Vivado (2021.2) with JTAG and correctly read the metrics and even program it with a bitstream.
Do you know why this may be?
I read somewhere that this might be due to a bad load on PS_INIT_B that creates a slow rise time, and can be fixed via patching the FSBL. But before I go down that road, I ask here.
Thanks
