Hello,

 

Camera Sensor : AR1335

RAW8 ,  640*480 ,  CSI clock -160MHZ , 2-lane, 2FPS

On the Denebola development board we are successfully streaming data onto the PC without any errors. 
On our custom board -where FPGA is present in between CX3 and AR1335. This FPGA is for Muxing purpose of 4 cameras into a single MIPI .Before going to muxing with multiple cameras just we are trying single camera streaming through FPGA.

Right now we are able to stream video through FPGA on to the PC but we are getting mipi errors with improper frame size 305280 bytes.  

Received Frame size : 305280
MIPI Error :  122  0  0  0  0  0  0  0  6
