Update FW on multiple VESC pcbs using CAN issue

Hi all

I have 10 VESC 4.12 connected via CAN bus

I can get and set settings on all of them, using VESC tool, and CAN forward feature.

When I want to update I have first downloaded newest bootloader on all of them using the usb cable
After that I conencted to one of them using USB, went to the Firmware tab, selecting my custom firmware.
I select the update ALL button, I can see the LED on all of the pcb's are flashing like sparkling..
Then its done, and I reset the power

Now ONLY the one I connected to using USB is updated

 

Am I doing something wrong ?
