So I’ve been testing with a CM5 and an official I/O board for now, and it seems like I need max_usb_current=1 in /boot/usercfg.txt for the SSD to reliably work as a system disk without surprise disconnects that cause the root filesystem to go read-only and the system belly up.
Has anybody tested out whether max_usb_current=1 causes any issues on the uConsole, combiend with a power-hungry CM5 board? I imagine with its built-in power supply, it could hit some sort of limit.
Update: I’ve just realized the CM5 I/O board has usb 3 ports, which is faster than the uConsole. I guess a usb 2 port might lower the SSDs power draw? Very interesting… The big question probably is, what max power draw will the uConsole allow through this usb 2 port? I now asked this here.
