Rust LPC54114

My attempt at getting Rust running on a heterogeneous dual-core LPC54114 microcontroller from NXP. This chip contains 2 cores, one Cortex-M4F (M4 with FPU) and one Cortex-M0+.

Install dependencies

# Add compilation targets for the Cortex M0+ and M4F procs
rustup target add thumbv6m-none-eabi thumbv7em-none-eabihf
# Add LLVM versions of binutils
rustup component add llvm-tools-preview
# Install Cargo wrappers for binutils' tools
cargo install cargo-binutils
# Install Just, our build script runner
cargo install just
# Install arm-none-eabi-gcc to build assembly files
apt install gcc-arm-none-eabi
# Install pyocd debugger and GDB
python3 -m pip install -U pyocd
apt install gdb-multiarch

Build

just build

Debugging

Start the GDB server

just start-gdb

Launch Cortex M4F

gdb -x debug.gdb

Note: If you don't have gdb-multiarch, you can also use arm-none-eabi-gdb

Launch Cortex M0+ coprocessor

gdb -x debug-coproc.gdb

Note: you need to launch the M4F first as it is responsible for flashing the elf image, copying the coprocessor's code into RAM, and pulling the M0+ out of reset.
