cant upload mios - no upload request

I used a virgin pic, flashed bootloader 1.2b using mplab and picstart plus programmer.

In mios studio -

received unexpected mios sysex message

= 00007E407001F7 expected = 00007E4000

And the midi in monitor shows the 00007E407001F7 coming in every 2 seconds

I also tried another pic with the same process as above…

How can I solve this?

You get an upload request - to me it seems like the PIC has the device ID set to 1, that’s why you get 00007E400 1 instead of 00007E400 0.

Someone correct me if I’m wrong =)

Yes, thats correct. It’s the PICstart issue, the programmer doesn’t write the correct ID (all-zero in normal case)

The workaround is described under the TEST_SW2 topic of this page: http://www.ucapps.de/howto_debug_midi.html
