TDA4VM: How to observe the transmission status of CSI2 on TDA4VM

Part Number: TDA4VM
Other Parts Discussed in Thread: AWR2243,

Tool/software:

Hi TI,

we connect TDA4VM with AWR2243 via CSI2, but now we can't capture AWR2243 radar image on linux via v4l2,v4l2 is blocked on deque buffer,

v4l2-ctl --verbose -d /dev/video2 --set-fmt-video=width=6144,height=256,pixelformat='RGGB' --stream-mmap=10 --stream-count=20,
so we want to observe the transmission status of CSI2 on TDA4VM by reading registers, how to observe on TDA4VM

early thread here, but kernel panic on TDA4VM,

Hi, Is this a demo or a customer project. As noted, the support for using radar sensor as image sensor is not validate in the TI SDK. Also, please provided info on other queries.

Thanks.
