Hi Team

I use the sample code from this E2E web: (96x_PGEN.zip) , 

https://e2e.ti.com/support/interface/f/138/p/721299/2662009

I use this py file : 964_patgen_fix_colorbar_1920x1080p30_yuv422_10b_400Mbps_4L.py

Then I capture a image from i.MX8, as below, is this image right? if on, what is the right image will be?

 Thanks

Leo

    Hi,
    it is not right.
    please refer to below reg. setting (you can read this reg. in UB964 d/s), it set 8 color bars in the pattern so the display panel should have 8 color bars.

    board.WriteReg(0xB1, 0x02) # PGEN_CFG
    board.WriteReg(0xB2, 0x35) # NUM_CBARS, Block_size

    best regards,
    Steven
