Build ameba-rtos

Navigate to the ameba-rtos root, load the build environment, and compile:

Linux / WSL: 
$ cd <workdir>/ameba-rtos
$ source env.sh
$ python3 ameba.py soc
$ python3 ameba.py build

Confirm that the build artifacts exist:

Linux / WSL: 
$ ls <workdir>/ameba-rtos/build_RTL8721F/boot.bin
$ ls <workdir>/ameba-rtos/build_RTL8721F/build/project_km4ns/image/km4ns_image2_all.bin

Build the Rust SDK

Run the build command from the Rust SDK root:

Linux / WSL: 
$ cd <workdir>/rust
$ cargo xtask build-amebagreen2 --example hello-world --sdk <workdir>/ameba-rtos

Expected output on success:

[package] xip=32B  sram=24576B  psram=32B  total=25760B
[package] build/amebagreen2/km4tz_image2_all.bin
[done] app.bin → build/amebagreen2/app.bin
