Hi Dmitry,

I tried having a single GPU frequency in the opp table, but when I run our software I get these messages and I don’t think the encoder/display is working:

*** ERROR -1 creating dumb buffer ***

*** ERROR -1 mapping dumb buffer ***

Could not map buffer exported through PRIME : Bad file descriptor (9)

Buffer : 0xffffffffffffffff

*** ERROR -1 creating dumb buffer ***

*** ERROR -1 mapping dumb buffer ***

Thanks,

This should be the settings. If you can get it to display on your analog TV, click the middle button (press in) then toggle it up/down to get to System then press in then you want Frame Rate and Freq like below.

Yes, it's just NTSC composite video. I think can configure for PAL too, but to do that you need to be able to see the video to do that.

In parallel, I've started the process of sending you another camera and board.

I'll check if I can find a capture device. Is it just a composite video signal or something more intelligent?

On one unit, we have seen the GPU fault crash at 118F (47C) while our custom board is sitting on a desk. The output of the GPU fault crash occurs once and our application continues to run. What do you think of this output?:
