I have a A320 overhead panel which is running 2 x Arduino Mega 2560s. The day before one of them has gone (which was commanding the left side of the Overhead panel) and yesterday the other one disappeared. In the MF Modules section now they seem to be "Compatible" whereas until yesterday that were Hakermann.
In the meantime, I sometimes 've been receiving "can't open port" warning while sometimes it stuck during uploading hex files. (Pls see pics attached). I almost begin to shout in the home enough is enough. Anyone can help me I will buy him a beer! 😉

It looks like you are trying to use some other app, we can't provide support for that

For flashing troubleshooting using mobiflight see this page: https://docs.mobiflight.com/guides/solving-flashing-errors/

Some other app? This is MF interface and hardware is Arduino 2560 mega. On top, I have no flashing issues.

Maybe your megas have the counterfeit ch340 chip and Windows updated the driver?

#

It happened to me after a Windows reset

You have screenshots showing xload

#

That isn't mobiflight

X-load was my last try to get the arduinos work with the panel. May be I did wrong. However, the issue that I mentioned happened well before I tried X load. Do you have any suggestions how to make arduinos recognised by PC (thru MF of course)

Yes, see the troubleshooting guide I mentioned above

Ok will do. However my issue is not flashing but about unrecognised arduinos. Is that guide referring to that as well?
