VESC Firmware Upgrade Guide: Why 6.05 and Two Methods

Firmware upgrades are essential before using a VESC. This guide covers VESC MK6 / MK6 HP and explains why we recommend firmware 6.05, along with two reliable upgrade methods.

Firmware selection: why 6.05?

• Some users have reported sensor detection issues or unexpected bugs in the latest releases.
• For competition or long-running deployments, verified stability matters more.
• The 6.05 release is the most widely used version in the community.

Firmware file selection

Always choose the firmware that matches your exact VESC hardware version.

Recommended files for MK6 / MK6 HP

• MK6: https://github.com/vedderb/vesc_fw_archive/blob/main/6.05/60_MK6/VESC_default.bin
• MK6 HP: https://github.com/vedderb/vesc_fw_archive/blob/main/6.05/60_MK6_HP/VESC_default.bin

Not recommended

• VESC_default_no_hw_limits.bin disables hardware protection limits, so it is not recommended for general use.

Method 1. Download the firmware file and upload it manually

The official firmware archive is hosted on GitHub.

• https://github.com/vedderb/vesc_fw_archive

Steps:

1. Download the .bin file for your hardware.
2. Open VESC Tool on your PC and connect to the VESC.
3. Go to the Firmware tab.
4. Select Custom File.
5. Upload the downloaded .bin file.
6. The VESC will reboot automatically after upload.
7. Reconnect and continue using it.

Method 2. Use VESC Tool Firmware Archive (online)

If your PC is online, you can use the built-in Firmware Archive feature in VESC Tool.

• It automatically detects your hardware and matches compatible firmware.
• The default selection is the latest version, so manually switch it to 6.05.

Wrap-up

The newest firmware is not always the most stable. For competition and research platforms, 6.05 remains a reasonable, well-tested choice. After upgrading, re-check motor and sensor settings, as they can be reset during the process.
