41CL Self-Update

[Neve]

Monte, Sylvain,
Thank you both for your valuable help. Just to let you know that, although I haven’t had the time to try the update process on the Mac, the method Monte suggested to test the connection works fine now. I assume the update process will perform flawlessly now.
Thanks to Sylvain’s pictures, I was able to see what was wrong. The Grnd was not connected to the right pin on the 2.5 female jack.
Problem solved. I’ll update this V5 board as soon as I have some time and let you guys know how it went.

Thank’s again to all those who tried to help.
