the second virtual USB-UART goes to the system controller on the motherboard, works too!
both UARTs are available through a single USB-C port at the rear of the case.
@mntmn the UARTs are available... Through a USB-C Port
What
@mntmn like they just appear as a standard ttyUSB on the device remote to the reform?
@ellenor2000 correct, 2x ttyUSB
@mntmn so they haven't invented an RS232 alt mode
@ellenor2000 i think there's some dirty way to do UART directly over CC pins or something, but i'm not doing that
@ellenor2000 sorry, SBU pins i guess
@mntmn@mastodon.social @ellenor2000@mastodon.top there's debug accessory mode, where you can do whatever
but requires a special cable/device to do so.
@ellenor2000 @mntmn technically you can put UART on the superspeed pairs or possibly the SBU lines I think when you're in debug alt-mode. This is what some pine64 devices do except they don't only do it on debug alt-mode :P
