@seka
I see your question.
There is no need to test with raspistill, the result should be the same as your python test.
I have some test suggestions that you can try.

Do not enable low_light mode.
Increase the speed of ae adjustment at the beginning of your scripts.

. / veye_mipi_i2c.sh-w-f aespeed-p1 0x64-p2 0x64

It's just for the purpose of pure testing.

@veye_xumm I just checked and another problem I have: I get no return value from the whitebalance mode and I cannot read its state also....

Seka

@seka Sorry, realised I had this error before: Problem: not current veye_mipi_i2c.sh ... solved now

Seka

@seka with regarding to your suggestion " do not enable low_light mode": When I disable it, images are very dark.... and I already have longest shutter settings....

Seka

@seka another problem that now occurs (and which has occured seldomly before): images are corrupted:

Seka

@seka ok, I understand now what the problem is: os.system does not reliably execute shell commands. When executing directly in the terminal ---> problem is gone. Thank you

Seka

@veye_xumm No, but I am currently assessing wether it is a light source problem or camera problem. Will get back soon..
