> * UART also seems to have different routing and I was not able to access NSH over pins. Hi, SAMv70 and SAMv71 MCUs should be basically the same (if the number of pins is the same, they ship it in 70, 100 and 144 pin variant if I recall), the difference will likely be just between UART pins routing. And peripherals on Xult vs QMTECH might be connected differently. SAMv7-Xult board has serial console on `USART1` compared to `UART0` on QMTECH and it is routed to the debug USB, the same CMSIS-DAP appears on. It's actually an interesting design from Microchip. There are two MCUs on Xult board, one is SAM and other is the older 16 bit PIC from Atmel's series that works as a bootloader and programmer. `USART1` from SAM MCU is actually routed there and PIC creates CDC-ACM USB device on USB debug port that can be used both as a programmer and debug console. They used the same design on 32 bit PIC32CZ, but with SAMe70 as a bootloader and programmer :smile: -- This is an automated message from the Apache Git Service.
