Hi Bryan,

k3-image-gen says UART0 is used as a debug interface. See
https://git.ti.com/cgit/k3-image-gen/k3-image-gen/tree/soc/am64x/evm/board-cfg.c#n81
So it seems that you can enable uart1 here. But people may run into a conflict with uart0 and k3-image-gen compiled with ENABLE_TRACE=1.
If I am wrong, can you please clarify why you mark uart1 as reserved.
Regards, Wadim
