FX3 / AR0134 Image Sensor – Not working ( Black Screen).
Design is based on App note: AN75779
– Inside debugger I made sure it is getting to next step past (SensorI2cBusTest).
Other tests checklist:
Added debug switch in the uvc.h file (DEBUG_PRINT_FRAME_COUNT)
Response: UVC: Completed 0 frames and 0 buffers
Counter is at zero and never changes:
Note from app note: If you do not see the incremental frame counter in the PC terminal program, there is probably a problem with the interface between FX3 and the image sensor (GPIF or sensor control/initialization).
I'm still using the same file (cyfxgpif2config.h) generated from the GPIF editor - from AN75779.
It enumerates correctly and shows up as the correct device FX3 - Using VirtualDub or other camer programs I just a black screen.
Does this mean I need to make changes in State machine, and I have a timing issue?
I'm not sure how to make the changes needed in GPIF editor -- I have Sensor Spec , but it is under NDA.
