BF706 YUV Image Capture Question

Category: Software

HI ADI's

My customer is trying to capture CIS (Pixel Plus POC030K) images using the BF706 CPU, but the following phenomenon occurs 

1) MCLK:25MHz (generated by timer), PCLK:25MHz -> Y only, YUV422 images are all cut in half.
2) MCLK:25MHz (generated by timer), PCLK:12.5MHz -> Y only image is normal, but wave-like appearance occurs in YUV422 image.

The EPPI and DMA settings files are attached.
Set EPPI and DMA related settings in the imc_configure function and start capturing through the imc_capture function.

(1) Image cut in half

(2) Normal image

(3) Image that appears to be shaking like a wave

Please check that

Thank you

  • Hi Andrew,

    1.In order to provide better assistance, could you please elaborate in detail regarding your application with a block diagram?
    2. You stated that the image displays normally with a clock frequency of 12.5MHz. Could you please try with less than 12.5MHz as PCLK frequency and let us know the behavior of the image?
