Sysex problems

[Guest Larry]

Hi,

I'm having problems with MIOS upload. When I should get the "request for upload" message I get two "key aftertouch" messages and a "system reset" message

.

I'm building the Midibox SID with 1 core module, 1 SID module and a minimal control unit. Should the other modules be connected to the core when uploading?

Hi Larry,

the code upload will also work without any module connected to the core.

So, possible reasons:

• you're using the wrong crystal, a 10 MHz type is required
  
• you've enabled the "To-COM" option in the PIC ID header, so that the MIDI interface is running with the wrong baudrate
  
• you've used an imperfect PIC programming software which doesn't write the PIC ID header correctly. IC-Prog works fine, but some time ago a user noticed problems with MPLAB IDE in conjunction with the PICstart programmer. I've written a patch which is available on request

Best Regards, Thorsten.
