Hello,
I am using focusrite audio interface to record the audio data with the same recording program to record the sound 24/7 in both odroidN2+ and odroidXU4. OdroidXU4 use arm71 architecture and odoridN2+ use aarch64 architecture. Therefore, before running the same program, I compiled main.c in those different device.
When I run the compiled C program in odroidXU4, there is no issue and it can run 24/7. But when I compiled the same program in odroidN2+ and run that compiled file in odroidN2+, the program can record only for 1 hours with no issue and the program seems hang but does not show any error.
When I check the sudo dmesg -l emerg, alert, crit,err , it shows the following message [quote]
