MBHP MF_NG Impossible to upload MIOS via MIDI please Help

Testing/Troubleshooting
1

Hello all,

 

I have a big problem to upload MIOS with MIOS Studio and it’s make me crazy !!!

 

So I have test with many midi support :

 

  • My internal E-MU 1616

  • An external M-Audio MIDISPORT 1x1

and the MIDIBOX STM32F4 with the MIDI IO and the USB MIDI 4x4 driver

 

nothing works always the same “No response from core after 16 retries!” message

My core is programmed with a PICKIT3 and it’s look ok

It’s send “[176405.191] f0 00 00 7e 40 00 01 f7” in loop that’s seems ok

 

MIOS STUDIO say “Bootloader is up & running!” that’s ok 

 

but when I start the upload of the Mios program it’s block

The leds of the midi support blinking so it’s confirmed that a midi message is send to the core

 

I join a screen capture of the MIOS STUDIO to illustrate my problem and I hoped that someone could help me because it’s very frustatring to blocked so near the goal

 

Thanks by advance, best regards.

It looks like your PICKIT3 hasn’t programmed the ID field to all-zero, therefore the bootloader sends an incomplete upload request.

 

You could fix this as described under “TEST SW2” at the bottom of this page: http://www.ucapps.de/howto_debug_midi.html

Thank you for your answer but I test it and it doesn’t work perhaps I lost something !!

 

I’ve programmed the PIC with Mplab IDE with the end setting to fff all is ok but when I put it to the core nothing happens in MIOS STUDIO …

 

Can you give me the good manipulation after the programming please ?

 

Thanks by advance,

 

Best regards.

Just to doublecheck: “TEST SW2” requires that you flash this program into the device: http://www.ucapps.de/mios/mios_bootstrap_picstart_workaround_v1.zip

It sets the ID field to 0000000000000000 which leads to a valid MIDI configuration.

 

Did you do this?

 

 

I’ve programmed the PIC with Mplab IDE with the end setting to fff all is ok

 

What do you mean with “end setting to fff” and what means “all is ok”?

 

Best Regards, Thorsten.

Hello Thorsten,

first I flashed the PIC with the program and I mean it’s well flashed by “all is ok”

For end setting to fff I’ve just respect your instructions in the asm file.

So what I don’t understand is :

What should I do after the PIC flashing ?!

I’m french sorry for my poor english !!

Thanks, best regards.

The program will reset the IDs to all-0

After you’ve booted the PIC with this program once, put it back into the programmer and flash the bootloader.

Thereafter it should be possible to upload MIOS via MIOS Studio

I’ve made this but it’s not solved my problem !!

Always the same issue…

The only explanation I have is, that your programming software overwrites the user id.

Actually this would be nice, because then I’m sure that in this case the software also allows to set the user id to all-zero

 

Where can I download the documentation about the software you are using?

 

Best Regards, Thorsten.

I’m using MPLAB IDE v8.92

 

I’ve test with disable the ID reprogramming but it’s not working within MIOS STUDIO (lots of aftertouch and pitchbend messages instead of MIOS request)

 

The user ID is set to 00000000 

 

Thanks for your help

 

Best regards

Is there any solutions !? I start to thinking that this project is to complicated for me…
