Hello to all,

I delete in the Mainwindow some unnecessary lines.
An suddenly i got the message, that the Firmware must be updated

After the Update the Board Shows only 'compatible' and all stored Infos are deleted.

I started manually the Update but always the process is terminated.

What can i do please?

Could Windows have updated something?

No, it happend while i deleted lines in the Mainwindow

#

Maybe the Board is defective suddenly

When i use a new board can i find the lost devices somewhere?

It is good practice to always save your board hardware config to a mfmc file. If you did, you only need to upload the file to the new board. Otherwise, the device list is gone.

#

Try rebooting. Is this a board with the CH340 chip?

Thanks, i have some mfmc files. Hopefully i can find the right one.

Regarding the CH340 i can look tomorrow.

Finally I used Arduino IDE to erase the EEPROM (i had to learn a lot).
After that mobiflight could upload the Firmware successfully.
And after reloading the mfmc file everything is ok again.
But I have no ideal why suddenly the Firmware was defective.

You can close this now and many thanks for our help
