Flashing G2 with Linux

This page assumes you have already built or downloaded gShield_flash.bin.

####Step 1. Install BOSSA flash programming utility.

Most likely (on Debian or Ubuntu), you will need to type the following in the terminal:

sudo apt-get install bossa-cli

Alternatively, you could get this utility from SourceForge.

####Step 2. Connect Arduino Due via micro-usb cable.

Make sure, you use the Programming USB port.

####Step 3. Activate bootloader:

stty -F /dev/ttyACM0 1200

####Step 4. Flash the chip with bossac:

bossac  --port=ttyACM0  -U true -e -w -v -i -b -R ./bin/gShield/gShield_flash.bin

It will output something like:

Erase flash

You're done. If everything went right, RX orange led should be slowly blinking. To connect to the board through serial, you will need to attach the cable to "Native USB" port.
