johnh Posted January 29, 2006 Author Report Share Posted January 29, 2006 I've been working with a working core + din4 this eveningrunning the MIDIO 128 application. I then attempted toupgrade my core to MIOS v1.8. I think the upload failedbut now when I power on I don't get any MIDI outputand just a row of black boxes on the LCD. Did I brickifythe PIC somehow? Hints? Debugging tips? This corehas been working fine for some months. Quote Link to comment Share on other sites More sharing options...
Jidis Posted January 30, 2006 Report Share Posted January 30, 2006 I think that's a common symptom of a bunch of different wiring/assembly/PIC burning mistakes we might make in a hurry. ;)I had a core a while back which did that. Mine would do a bad boot "most" of the time, and you could often get a proper one by quickly flicking the power off and on a few times.I fixed it, but I'm sorry to say, I can't remember exactly what it was. There may be an archived post in here. When I looked, there were other problem posts like that, which weren't from the same thing. I also managed to kill a 2x40 LCD during the troubleshooting, while tinkering with the rectifier circuit.Hope you get it worked out!George Quote Link to comment Share on other sites More sharing options...
