This may be a typo on your side, but I'm testing with an MX, not an MZ. I did just try it with that simulator, and I get an error about writing to peripheral register 1f800600 being not supported. Here's the branch that I'm working off of at the moment. It also has a fix for defining CONFIG_SERIAL_TERMIOS with the PIC32, which doesn't properly compile: https://github.com/rm5248/incubator-nuttx/tree/pic-messing-around You should be able to get the proper configuration by doing ./tools/configure.sh -E -l pic32mx-explorer16:nsh. Note that the explorer16 has the output on UART2 - I don't remember if you can switch which UART qemu is using to see that output. Switching it to UART1 for the simulator should be fine though. -Robert Middleton
