I was wondering if anyone could help me troubleshoot this problem?· I've been getting this error when loading either ROM or RAM.· It displays·while "verifying ram".· It occurred·occasionally at first, but it has·gradually gotten worse.· Now it takes 5 or 6 tries to get a program loaded.

    What hardware are you using?

    FWIW, I've never had any problems like that with a Proto board, my own Propeller boards or a prototype data logger board that I'm developing software for. I've got plenty of hardware and two Prop Plugs, which would help with that sort of problem.

    Try communicating with the PC via the Prop Plug, using serial code and a terminal program. Sending continuous data via the Prop Plug might indicate the cause of the problem.

    Check the Prop Plug connector solder joints on the Proto board, as well. One of them might be intermittent. You could see if wiggling the Prop Plug makes a difference.

    You aren't powering it from a battery, are you?

    I have the problem with both batteries and wall wart.· I did try a fresh set of batteries.· I haven't tried your suggestions yet, though.
