This project contains extension for buildroot project. Main purposes:
- Train embedded development technics
- MVP for auto-tests
- GCC 7.4 - 9.x
- make
- cpio
- rsync
- bc
- qemu
You can use docker image buildroot/base instead.
# Create images
make
# Smoke run
make test
# Play inside of firmware
make qemu_shellThe project tries to reproduce real hardware (not malta) and run in QEMU. Many hardware vendors use the u-boot as bootloader for their boards. So in this project we have to use the same way to boot:
u-boot -> Linux Kernel -> Application
# Start qemu
make qemu_shell
# 1. Wait for Linux boot
# 2. Login with root/root credentials
# 3. Print u-boot environment
fw_printenv
# 4. Change and check u-boot environment
fw_setenv test success
reboot
# 5. After u-boot starts you have 2 seconds to interrupt the boot process - just hit ENTER
# 6. Check the environment
> printenv test
test=success# 1. Create update file
make update
# 2. In separated console create simple http-server (thats how we download the update)
python3 -m http.server -b YOUR_IP
# 3. Start qemu
make qemu_shell
# 4. Wait for Linux boot
# 5. Login with root/root credentials
# 6. Check current system status
rauc status
# 6.1. Output example

# 7. Install update
