-In recent Debian versions (>= 12), it seems that the `'enable_uart=1'` option does more harm than good. I advise you to delete `enable_uart=1` in /boot/config.txt, and keep the two `dtoverlay` lines.
+In recent Debian versions (>= 12), it seems that the `'enable_uart=1'` option does more harm than good. I advise you to delete `enable_uart=1` in /boot/config.txt, and keep the two `dtoverlay` lines, at least on RPI Zero (Ok on RPI 4B).
 
 For MIDI scripting I recommend using [Python MIDO](https://mido.readthedocs.io/en/stable/) which is packaged for Debian.
