Hello,

I’m going to develop camera driver with os05a20 image sensor on TK1 platform, with 4-lane configuration.
but an issue was raised:

All of the status were 0, it could be csi/vi didn’t get any validate frame data from MIPI bus.
You may need to probe the signal to make sure the MIPI signal is match the csi spec.

After some modification we have following error.In that status have values.

Looks like the sensor output size not as expect.
Have a check the TRM the CSI_CSI_PIXEL_PARSER_A_STATUS_0 show detail information.
