To my understanding both host mode and OTG mode could be supported by
the hardware.
Jumper J17 on
https://www.microsemi.com/images/10/MicrosoftTeams-image%201.png.
USB device mode selection - Open: USB client. Closed: USB host
Is OTG really the most important scenario for running the board? I
personally would prefer to run it in host mode to add more peripherals.
What is missing on the driver side to enable host mode?
Can we detect the 5 Volt jumper setting via GPIO?
Best regards
Heinrich

Nothing. I'll drop the the patch for v2 :)

I have to check if a GPIO can be routed that way & I'll get back to you.
Thanks,

Unfortunately not, that jumper can't be connected to a GPIO.
