Upcoming moOde 9.0.0 (Bookworm)

[TheOldPresbyope]

Sorry, it's the new Pi-5B 1.0 4GB, the only one I own now. Moode image on a 32GB microSD card. The 4TB external USB powered HD only stores music.
As I'm waiting for a new transformer to build a linear power supply (LT1084 IC based) I'm temporarily powering the Pi5 by a mobile phone USB C PD charger. Although it's a 30W one it can only supply a 3A current when its output is 5V (9V=3A; 15V=2A; 20V=1.5A). Probably with a proper 5A @ 5V PD charger, the Pi5's power consumption is higher than its predecessors, I wouldn't have had any problem with my HD as the maximum output current on the USB outputs would be automatically set by the system.
But also in the past, as far as I can remember, with the Pi4 I also had to modify the config.txt file (the command should be a bit different).
Anyway, outside the PD chargers world, I suspect that I should edit the file even if my linear PSU could deliver 10Amps@5.1V. I could let you know later if you're interested in this information.

The Pi 5B "knows" whether a USB-C power source can supply more than 3A because of the information communicated from the source via the USB-C configuration channel. If your linear supply doesn't duplicate this behavior, the Pi 5B firmware will not enable USB boot even if more current is available, unless you override the settings.

Or at least that's how I understand it.

The Pi firmware is getting more complicated all the time. While the documentation is pretty good it tends to lag (surprise!) and is not very detailed in places.

Keep us posted.
