Problem with Core Oscilator

Testing/Troubleshooting
1

Hi all,

I’m working on a midibox LC. My problem is the Core module.

I’ve loaded the Mackie emulation program to the PIC with a pic

programmer but I can’t get the 10Mhz Oscilator working.

All voltages at the PIC are correct.

What can I do?

regards Dietmar

hi,

are you sure that the problem come from the crystal?

you say:

I’ve loaded the Mackie emulation program to the PIC with a pic

programmer

but you don’t have to use a pic programmer to upload the MIOS and the app, you only need a pic programmer to burn the “bootstrap loader”, then you can upload first the MIOS thru a standard MIDI interface, and one time the MIOS is correctly uploaded ,you have to upload the MIDIbox LC application via MIDI too..

I’ve burned the LC emulation for mackie control and nothing else.

Do I need the bootstrap loader? I thought that the LC emulation

is a complete softwarepackage and it don’t need anything else.

I’m testing the core module in a Lab, but I don’t have a PC with

midi interface here, so I burned the software via PIC programmer.

do you use a pre-burned PIC from Smash-tv shop or Mike’s SHOP?

you can’t burn the app with a burner, only thru MIDI.

So, the steps are:

  1. if you use a blank new PIC, download the bootstrap loader on Ucapps.

Burn it with your pic programmer.

if you use a pre-burned Pic, go to step 2

2.one time the bootstrap is burned , upload the MIOS via MIDI

  1. now you can upload the app, via MIDI too.

but maybe, if you are using a pre-burned PIC, the bootstrap loader have been overwritten when you burn the app with your burner, check if you get the right request in your MIDI monitor…

You build your own board, or using a kit/someone’s design?

sounds like you need to go back and do some reading!

You’re right. The LC emulation is a complete application for MIOS … not for the PIC.

In other words: First load the operationg system (MIOS), then the application (LC)
