## Upload to VESC
### Method 1 - Flash it using an STLink SWD debugger
Build and flash the [bootloader](https://github.com/vedderb/bldc-bootloader) first
```bash
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**]
```bash
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
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. 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" ]**
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.
## 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.
