41CL Update stops with * in display

[Monte Dalrymple]

The symptoms indicate that the YUPS image may be corrupted. Is the keyboard responsive after it stops? If yes, that means that the "*" is being displayed as an error message. The problem is that "*" doesn't appear anywhere in the YUPS error messages, but _is_ in the ALPHA register, so the code must be somehow jumping to the error output without actually writing an error string. What version of YUPS are you using? Have you checked the YCRC of the YUPS image to see if it is corrupted? Have you tried specifying an explicit range for the FLCHK? function? Something like "000>3FF"? If you have an older version of YUPS I would first download the latest version to RAM and then plug in that version instead of the one in Flash and use it. That will shorten the FLCHK? time by using the CPONLY option.
