Could you please pick one post and answer on that?
It’s really hard to track down everything you have done.

Why are you not using CAN?


Hi Philip,

I have tried to update firmware on 2 different computers (both windows 10) but get the message “no update available”

does this mean that the latest firmware is already loaded? or do I have a problem with the loading of the bootloader?




I think you are trying update online feature. Don’t click the option which prompts to search online, instead choose local file. You are supposed to navigate to local file that you have downloaded from the link in the instruction.


You need to update the boot loader then update the firmware.

This is 2 separate updates, follow the doc and it will lead you though this.
