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

Prerequisites

On Ubuntu

Install the gcc-arm-embedded toolchain. Recommended version gcc-arm-none-eabi-7-2018-q2

Method 1 - Through Official GNU Arm Embedded Toolchain Downloads

  1. Go to GNU Arm Embedded Toolchain Downloads
  2. Locate and Download version gcc-arm-none-eabi-7-2018-q2 for your machine
    GNU Arm Embedded Toolchain: 7-2018-q2-update June 27, 2018
    Linux 64-bit version can be downloaded from here
  3. Unpack the archive in the file manager by right-clicking on it and select "extract here"
  4. Change directory to the unpacked folder, unpack it in /usr/local by execute the following command
    cd gcc-arm-none-eabi-7-2018-q2-update-linux  
    sudo cp -RT gcc-arm-none-eabi-7-2018-q2-update/ /usr/local  
    

Method 2 - Through apt install

sudo add-apt-repository ppa:team-gcc-arm-embedded/ppa
sudo apt update
sudo apt install gcc-arm-embedded

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

On MacOS

Go to the GNU ARM embedded toolchain downloads Website and select the mac version, download it and extract it to your user directory.

Append the bin directory to your $PATH. For example:

export PATH="$PATH:/Users/your-name/gcc-arm-none-eabi-8-2019-q3-update/bin/"

Install stlink and openocd

brew install stlink
brew install openocd

Build

Clone and build the firmware

git clone https://github.com/vedderb/bldc.git vesc_firmware
cd vesc_firmware
make

Upload to VESC

Method 1 - Flash it using an STLink SWD debugger

Build and flash the bootloader first

make upload

Method 2 - Upload Firmware via VESC tool through USB

  1. Clone and build the firmware in .bin format

Reminder : Remember to select your board in [conf_general.h]

git clone https://github.com/vedderb/bldc.git vesc_firmware
cd vesc_firmware
#make build/your_firmware_name_here.bin
make build/VESC_fw.bin 

In VESC tool

  1. Connect to the VESC
  2. Navigate to the Firmware tab on the left side menu
  3. Click on Custom file tab
  4. Click on the folder icon to select the built firmware in .bin format (e.g. VESC_fw.bin)
[ Reminder : It is normal to see VESC disconnects during the firmware upload process ]
[ Warning : DO NOT DISCONNECT POWER/USB to VESC during the upload process, or you will risk bricking your VESC ]
[ Warning : ONLY DISCONNECT your VESC 10s after the upload loading bar completed and "FW Upload DONE" ]
  1. Press the upload firmware button (downward arrow) on the bottom right to start upload the selected firmware.
  2. Wait for 10s after the loading bar completed (Warning: unplug sooner will risk bricking your VESC)
  3. The VESC will disconnect itself after new firmware is uploaded.

In case you bricked your VESC

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.
