PS_POR_B connected to PL as well as PS?
The pushbutton/power supply sequence circuit creates PS_POR_B
- is this signal sometimes intended to be driven by the PL logic?
(e.g. watchdog behaviour to force a reconfig of the PS or similar)
if it is, can you please modify the port directions so it's all bidirectional if it isn't, can you please consider adding a buffer so that a PL configuration can't potentially trigger POR: it might end up in a deadlock
