All of them!

Check the supported boards by typing make

[Firmware]
     fw   - Build firmware for default target
                            supported boards are: 100_250 100_250_no_limits 100_500...

There are also many other options that can be changed in conf_general.h.

• Tools: git, wget, and make
• Additional Linux requirements: libgl-dev and libxcb-xinerama0
• Helpful Ubuntu commands:

sudo apt install git build-essential libgl-dev libxcb-xinerama0 wget git-gui

• Helpful macOS tools:

brew install stlink
brew install openocd

• Chocolately: https://chocolatey.org/install
• Git: https://git-scm.com/download/win. Make sure to click any boxes to add Git to your Environment (aka PATH)

Open up a terminal

1. git clone http://github.com/vedderb/bldc.git
2. cd bldc
3. Continue with On all platforms

1. Open up a Windows Powershell terminal (Resist the urge to run Powershell as administrator, that will break things)
2. Type choco install make
3. git clone http://github.com/vedderb/bldc
4. cd bldc
5. Continue with On all platforms

1. git checkout origin/master
2. make arm_sdk_install
3. make <-- Pick out the name of your target device from the supported boards list. For instance, I have a Trampa VESC 100/250, so my target is 100_250
4. make 100_250 <-- This will build the VESC 100/250 firmware and place it into the bldc/builds/100_250/ directory

Linux Optional - Add udev rules to use the stlink v2 programmer without being root

wget vedder.se/Temp/49-stlinkv2.rules
sudo mv 49-stlinkv2.rules /etc/udev/rules.d/
sudo udevadm trigger

• python3, and pip

• Python 3: https://www.python.org/downloads/. Make sure to click the box to add Python3 to your Environment.

1. pip install aqtinstall
2. make qt_install

1. Build and flash the bootloader first
2. Then _flash to the target of your choice. So for instance, for the VESC 100/250:

make 100_250_flash

1. Clone and build the firmware in .bin format as in the above Build instructions

In VESC tool

2. Connect to the VESC
3. Navigate to the Firmware tab on the left side menu
4. Click on Custom file tab
5. Click on the folder icon to select the built firmware in .bin format (e.g. build/100_250/100_250.bin)

6. Press the upload firmware button (downward arrow) on the bottom right to start upload the selected firmware.
7. Wait for 10s after the loading bar completed (Warning: unplug sooner will risk bricking your VESC)
8. The VESC will disconnect itself after new firmware is uploaded.

you will need to upload a new working firmware to the VESC.
However, to upload a firmware to a bricked VESC, you have to use a SWD Debugger.
