Sometime robot resets while pairing

[Gregwar]

I was connected to a robot when it happens and got the backtrace

Guru Meditation Error: Core  0 panic'ed (LoadProhibited). Exception was unhandled.

Problem: I don't have the exact firmware.elf that was deployed back then when I got the stack trace

To debug:

• Flash the robots with a known firmware.elf
• Plug with USB to one robot during pairing to get a similar stack dump as the one above

Then it will be useable to investigate the stack trace
