Unable to update focbox firmware from 2.18

After connecting to VESC tool and trying to upload firmware I get:

  1. a serial port connection error at end of flash
  2. firmware upload ok but focbox doesn’t reboot.

Upon reboot the focbox still has old firmware 2.18.

What I’ve tried:

  • downloading previous versions of vesc tool/accompanied and trying to update incrementalyy but no dice
  • uploading bootloader first and then flashing firmware both with and without power cycle.

Any ideas?

I’m having the exact same issue. Did u manage to find a solution?

Bootloader changed after 5.03. Try this:

Firmware archive for 5.03 on the original focbox

No joy unfortunately
