Hi Mario,
Unfortunately I don’t have the expertise to poke any further into the driver design of PCam5C for KV260 PYNQ. I do sense there is something inherently wrong under the surface I’m just unsure where.
After reading: Pcam not generating frames · Issue #27 · Xilinx/Kria-PYNQ · GitHub I have realised I am in the same boat. The camera can be seen at address 3c only after mipi.start() is entered from the top level in python.
But writing to this address at all using axi.iic.send/recieve from the axi iic class defined under pynq/lib (https://github.com/Xilinx/PYNQ/blob/master/pynq/lib/iic.py), works (doesn’t prompt an error) but reading the output from the command reads nothing. The only output is whatever integer is entered in either the send/receive function, should this be the case?
It would be great to have someone look into the problem as it has clearly troubled some people, particularly I would say because the Xilinx KV260 board is advertised as the go to board for all things vision related - including its “plug and play” rpi camera connector.
Thanks,
Cameron
