7 years ago This has been resolved. It's timing related. I was using a remote X server which slowed down the main loop just enough. I'm guessing your 1541 code must run in the main loop instead of a separate thread.

I can't get past this particular issue. About one in 50 tries I manage to get a directory listing, but it usually fails with something like the following. I have tried an Uno and a Nano using /dev/ACM0 as well as /dev/AMA0 and /dev/ttyS0 (switching the two UARTS on RP3).
