Hardware information (UARTs etc.)

I recently purchased an Upxtreme i14 with the hope of working on adding open source EDK2 firmware support for it to replace the Up Squared in edk2-platforms.
I understand that the hardware isn’t open, but I was hoping to find more information about the hardware than I can see in the user manual - for example what the different UARTs are for at a minimum.
Do you have any more information you can share with me, or will more detailed information be available in future?

Hi @bcran
Intel has not yet completed the slim bootloader instructions for UPX-MTL.
If there are updates, we will notify you immediately.Or you can refer to the link first.

Hi @HarryChiu,
Sorry but I wasn't asking about firmware support. I was asking about documentation for connecting up the serial ports to the UARTS etc. - for example which port is the serial console, which debug etc.
