Still programming problems

Testing/Troubleshooting
1

I still got the decribed behaviour.

  • I used external power (18V) for JDM.

Ok, programming seems to work without problems.

Even progrmming a 00-Buffer works now.

  • I sacrificed the first PIC and soldered another one to explude that this PIC was really detroyed.

(BTW: I noticed that this new PIC could not be programmed without external power for the JDM, the older one could, but with errors, and reading problems - never the same reading result)

  • I burned the bootloader (ok)

  • I uploaded MIOS via sysex (ok, no error string)

But MIOS will not run correctly. I get the request from the prim bootloader again and again. After each 2s.

So I can imagine that there are only some possibilities:

1.)  MIOS is not uploaded correctly (not very likely)

2.)  MIOS crashes (my guess)

3.)  MIOS has a bug (not very likely)

Any Ideas?

try loading MIOS again, sometimes I have to have a couple of goes, sometimes I don’t! Remember you only have 2 seconds after turn-on to do it!

That would be true if nothing will ne loaded.

But the bootloader sends correct acknowledge-messages with the rigth check sum.

And if I read the PIC out than there was something loaded into the flash.

I only have to check if this procedure works 100% correctly. Not today, perhaps this evening.
