Upgrade Rev 2.0

[OLIVIER]

Hello,
I want to install GRBL 1.1.F on my Rev 2.0 card
What should I use as a USB driver?
Should I update the map to 2.3?
For the moment I can not transfer the software, the card does not respond while with the GRBL 0.9 it works fine

we will post the tutorials later about how to upgrade from Rev2.0 to 2.3

Thanks

Dear

Do I understand that my Bootloader is broken?
And that it is necessary to re-load it?

Dear,


I just updated the bootloader with the key.
Whenever I want to update the configuration files, I have to reset the key
Each time I have the following message, is it normal (If I don't use the key)?

Hi Mate, replied your question in email.

Could you check:
-Pull the BL upgrade key from after BL programming is done (stop flashing)
