dneez Posted March 29, 2006 Report Share Posted March 29, 2006 I connect core via gameport. Till yesterday I was able to upload apps. Then I connected both DIN modules and soldered encoders. After that my MB has started to behave strangely. I thought it was core not configured. But when I tried to upload new main.hex, i wasn't able. I disconnected DINs and still no luck.Done troubleshooting excluding steps involving optocoupler, as I do not have it connected, as I use 1:1 gameport connection.Shortening pins on game port connector works. Shortening RX TX pins works. Cable is OK. I do recieve upload request after start up.Could it be that I fried some portion of PIC? Is there a way to check it?EDIT: One more thing I noticed, when i disconnect power I get one or combination of following. 00000AE8 10 -- FE -- -- -- --- Active Sensing 000023B6 10 -- FC -- -- -- --- Stop 000023B8 10 -- FF -- -- -- --- System Reset 000449BE 10 -- F8 -- -- -- --- Timing Clock Is it normal?

dneez Posted March 31, 2006 Author Report Share Posted March 31, 2006 Success!It seems I really messed up PIC. After replacing it and some debugging I now have 99.9% working MidiBox. Have to replace one multiplexer before it is 100% :) Quote Link to comment Share on other sites More sharing options...
TK. Posted April 1, 2006 Report Share Posted April 1, 2006 You wrote, that the old PIC sends an upload request during startup. This means, that you should be able to upload MIOS and the application again, right?Maybe the upload was errornous during the first try, MIOS Studio normaly reports this, did you notice any special message?Best Regards, Thorsten.
