Is mt9t001 driver working properly?

I simulated a CMOS 480p output with FPGA to DVEVM(dm355), slightly modified ipipe_480p_example.

There should be I2C initiated error message when call MT9T001 driver cause I didn't simulate I2C SDATA, SCLK. But when running ipipe_480_example, I didn't see any error message , the main programe hangs when CaptureFrame(&xx). I wonder if mt9t001 driver is working well...

I wonder where is the problem, thanks in advance.

    Please note that the drivers we provide in the DVSDK are slightly different than the drivers provided by Leopard Imaging with their camera kits.  I was just taking a look at our DVSDK drivers and it appears that if you have the mt9t driver enabled in the kernel and the proper confiugration is passed via u-boot, you should see an error similar to

    Failed to register MT9T001 I2C client

    during your boot log if there is not MT9T sensor detected.

    I checked my u-boot session log, find some I2C Neck error messages there, that is I2C addressing error.

    Thanks Juan.
