MPS2 AN521 Board

This board configuration will use QEMU to emulate generic ARM v8-M series hardware platform and provides support for these devices:

• ARM Generic Timer

• CMSDK UART controller

Getting Started

1. Configuring NuttX and compile (Single Core):

   $ ./tools/configure.sh -l mps2-an521:nsh
   $ make
   

Running with qemu:

$ qemu-system-arm -M mps2-an521 -nographic -chardev stdio,id=con,mux=on \
-serial chardev:con -mon chardev=con,mode=readline -kernel ./nuttx

Debugging with QEMU

The nuttx ELF image can be debugged with QEMU.

1. To debug the nuttx (ELF) with symbols, make sure the following change have applied to defconfig:

   CONFIG_DEBUG_SYMBOLS=y
   

2. Run QEMU (at shell terminal 1):

   qemu-system-arm -M mps2-an521 -nographic -chardev stdio,id=con,mux=on \
   -serial chardev:con -mon chardev=con,mode=readline -kernel ./nuttx -S -s
   

3. Run gdb with TUI, connect to QEMU, load nuttx and continue (at shell terminal 2):

   $ arm-none-eabi-gdb -tui --eval-command='target remote localhost:1234' nuttx
