Other Parts Discussed in Thread: AWR1243
Hello,
We have a system with AWR1243 radar sensor communicating with DS90UB953 serializer. The serializer communicates with a remote host, which consists of a UB954 deserializer (the EVM) along with an FPGA for data acquisition.
The strange behavior we observe is that ~50% of the time, the system functions as intended. The other ~50% of the time, no data is sent over the link. The configuration is identical in all cases, and starts from an identical initial condition. By probing the board trace we can confirm that CSI2 traffic is generated by the AWR1243 sensor in all cases, so the issue is somewhere downstream. The line/frame length and datatype registers in the serializer are also correct, which indicates it is at least receiving the CSI2 traffic.
To help us debug this issue, can you help answer these questions:
- Is it possible for the 953 or 954 chips to enter a "bad state" where they do not forward CSI2 data?
- Which device registers can we poll to understand the device and link state?
Thanks,
Antonio
