v3.1.0 fails to upload firmware on Mac M3 Sonoma (v.3.0.0 OK)

Hi there,

The newest release doesn't seem to work on my machine (Mac M3 Sonoma), whereas v.3.0.0 is ok.

I tried all baud rates with no luck. I'm suspicious it has something to do with this issue but it seems that I am having the opposite issue. I'm traveling right now but will investigate the RTS/DTR signals when I can return to the lab.

I am using a USB-to-Serial CH340.

Thanks!

Hi @derekpickell ,

Thanks for reporting.

To be honest, CH340 support on MacOS is a bit of a nightmare. The behaviour of RTS and DTR seems to change between OS versions. If 3.0.0 is working for you, I suggest just sticking with that. ;-)

I'll leave this open to make it easier to find, for anyone else facing the same issue.

Best wishes,
Paul
