Reset MIOS?

[johnh]

Hmm.  Things are working again.  Something must be flakey.  Oh Joy!

I've been working with a working core + din4 this evening

running the MIDIO 128 application.  I then attempted to

upgrade my core to MIOS v1.8.  I think the upload failed

but now when I power on I don't get any MIDI output

and just a row of black boxes on the LCD.  Did I brickify

the PIC somehow?  Hints?  Debugging tips?  This core

has been working fine for some months.

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!
