Hello, thank you for your reply. I tried the cma-384 but the Pi was unable to boot. There was just a black screen. So I returned it back to cma-256.
I also tried to reinstall the latest "raspios_lite_arm64-2024-03-15" but it also did not help.
Before I try the suggested python script: How is it with power consuption when the camera remains running? I use it on remote location running just from powerbank and therefore my power resources are limited.
Here is fresh info from journalctl. I don't understand all that information but I can see, that the cma seems to be realy utilized. Is there a way to clear or flush or defragment the cma space?
Thank you for any advice.
