famo:
I confirm: right now I've reinstalled the bootloader using the VidorFPGARecovery files.
The Philippe's blinking led now works (!) but my own project stops uploading ad 37%.
I remember this 37% has been experienced by someone in the forum, I have to search the thread.Do you know if VidorFPGARecovery is equivalent to SAMD_BootloaderUpdater?
Very funny: further attempts to load the Philippe's example now hangs all at 62%
(also after power supply reboot)
