Flashing g2core with Windows

This page is for uploading an already compiled G2 binary to a target board without a debugger from Windows. Please see Getting Started with g2core Development for information about other options.

Step 1 - Get the g2core.bin file

Option 1 - Compile your own using the instruction in Compiling the Code

Option 2 - Get the g2core.bin binary firmware files from https://github.com/synthetos/g2/releases

• Click the "Assets" drop down for any of the releases. The various g2core.bin files will be displayed, with names appropriate for specific boards we have configuration files for.

In either case you'll need to note the path to the resulting binary file. For example, if it's called g2core.bin and it's in the Downloads directory of your home page, you would use %HOMEPATH%\Downloads\g2core.bin. We'll call this PATH_TO_BINARY in the commands below.

Step 2 - Download the arduino-flash-tools

The arduino-flash-tools repo contains the bossac utility. You can download the zip file here.

Expand the zip file in a location where you know the path, and note that path.

Step 3 - Program g2core using bossac.exe

Hold down the Windows Key and press r then type cmd.exe and hit enter:

• cd path to expanded zip file contents
  
• cd tools_windows\bossac\bin
  

Run the mode command by itself and it should return a COMx. Note your port number for x to use as COMx in the following commands. Remember from above that PATH_TO_BINARY is to be replaced with the path to the downloaded or compiled .bin file.

After that go ahead and run these commands, replacing COMx with your port, like this: COM4.

• mode COMx BAUD=1200
• bossac.exe --port=COMx -U false -e -w -v -b PATH_TO_BINARY -R
