Can you please elaborate more on the issue that you are facing, for me to better understand it?
Can you please elaborate on how you verified this, "no MIPI lock condition on receiver"?
with firmware tested on two first boards (frame size is consistent, just not all frames are received by deserialiser IC - we are narrowing it down) next three See3CAM_CX3RDK are receiving frames with improper size and resulting framerate is equal zero. I need to pinpoint it, but I will need assistance.
Our custom shield is using 1.8V and 5V from RDK's base board and voltages are present.
Can you please share the UART debug logs in both the cases, working and non-working boards to understand the issue better?
"next three See3CAM_CX3RDK are receiving frames with improper size and resulting framerate is equal zero."
=> Is the improper size being transmitted from the sensor side or is it being received improper by CX3 and transferred to host incorrectly?
Also, can you share Wireshark traces for both the cases to understand the issue better?
I will reply to this question in a week, I am away from laboratory so no testing can be performed atm
