Problem Updating from 2.3 to 3.1

MIDIbox SEQ
1

Hello there,

I have a seq that was working fine on 2.3 .  I’m using an 18f452 pic. 

I have uploaded the new MIOS and bootloader.  (update_with_old_mios.hex)

I got this on the feedback:

[D0 1A 00] Channel 1: Channel Pressure value: 26

The LCD now reads:

Bootloader is up-to-date

Now when I try to upload the 3.1 (setup_mbseq_v3.HEX) here is what I get:

00000002852470 ms | [EE 02 00] Channel 15: Pitch Bend value: 2

00000002854556 ms | Sysex message: F0 00 00 7E 40 00 01 F7

00000002856446 ms | [EE 02 00] Channel 15: Pitch Bend value: 2

00000002858532 ms | Sysex message: F0 00 00 7E 40 00 01 F7

00000002860425 ms | [EE 02 00] Channel 15: Pitch Bend value: 2

The uploader says:

Sending block 00008000-000080FF

Received error code 05: Write access failed (invalid address range) - used by 1st level bsl

Aborting after 16 errors

After that I have to reinstall the mios to get anything to appear on the screen.

Not sure what is going on.  It did work with the earlier version.

Thank you for any help.

Perfect, this demonstrates that the “fail save” protection is working! :slight_smile:

From the ChangeLog:

  o this version *REQUIRES* a PIC18F4620, it won't run on a PIC18F452 !


  o there is now a check during the initialisation for the PIC derivative.
    Execution from any other PIC than PIC18F4620 is gracefully prevented.
    You will see a message on screen, and a MIDI event "EE <devid[2:0]> <devid2[9:3]>
    is sent to notify about the wrong PIC
[/code]
