Ears driver behaviour on Pi Zero 2 (armv7l)
f-laurens opened this issue · comments
On Pi Zero 2 platform running a 32 bit (armv7l) image, ear movements flood kernel log with traces below.
There is no problem with ear behaviour, which appears to be fine.
But the repeated writes to /var/log/kern.log /var/log/messages on the SD card makes the behaviour of the zero2_raspios Pynab image somewhat sluggish.
There is no such adverse effect with the zero2_dietpi image, where logs are generated in RAM and quickly rotated.

Thanks. Can you please push the fix to release branch, so that it is used when building Pynab release images?
