Hello, I’m having same issue.
Device reset sequence finished!
Cannot initialize ESP-AT Lib!
I follow both procedures to upgrade firmware (UF2 and ambd_flash_tool.py2) but firmware upgrade does not work…
Using the UF2 procedure show in screen the message " Burn RTL8720 fw" but don’t finish (at least I can’t see any message indicating that).
Using the ambd_flash_tool.py procedure it returns:
Do you have any suggest.
