Hi Dmitry,
I am running the 4000 as follows to cause the GPU hang bug:
- Board in a freezer – ours isn’t super controllable, but a thermometer says it is at -18C.
- Set up so that you can cycle the board power – needed when you hit the crash
- I have a small fan in the freezer pointed at the board with a power cord coming out so that I can turn it on and off.
- Default parameters on the 4000 except
- Cam 0 is set up with TestPattern Multi Car, 1080x1920, color
- Stream network video to your PC
- Parameters -> Save To Board
- View Performance Graphs, check Enable System Status and look at the Temperature value (see below)
- Try to get the temperature into the high 50’sF to low 60’sF (sorry it’s F instead of C!) and you will see: Warning: GPU hang detected … messages and jumpy video.
- Turn on the fan if the temperature is too high (usually not for very long)
- You can try turning on other processing temporarily if the temperature is too low, then turn these off once it warms up.
i. Enhance -> Contrast Mode = CLAHE
ii. Track -> Detect -> Mode = Aerial
- Occasionally, the whole system will crash, requires a power cycle
- Let’s get on a call if you are struggling to get it into the zone.
Thanks,
Jordan
