This Nerves firmware is used to flash BeagleBone Black eMMC. It includes a Nerves .fw file that is an "empty" Elixir Application just to get something on the eMMC. Not necessary, but if you would like to change the intial firmware just copy your projects .fw file to ./rootfs_overlays/nerves/emmc_firmware.fw.
This project can only target the Beaglebone so you should use MIX_TARGET=bbb for all nerves commands.
To start your Nerves app:
export MIX_TARGET=bbb- Install dependencies with
mix deps.get - Create firmware with
mix firmware - Burn to an uSD card with
mix burn - Insert the uSD card in BeagleBone
- Power the BeagleBone while holding down the S2 button.
- Wait for flashing to complete. Behavior: The leds will have "normal" flashing patterns for a few seconds before going into a sweeping pattern. After the sweeping pattern completes all LEDs will go solid and the Beaglebone will power off.
- Remove uSD card from BeagleBone
- Power on the BeagleBone and enjoy!
- You can now update with OTA methods (eg
mix upload) with firmware using the Nerves BBB eMMC System
