[SOLVED] Need Help - No Testone on MB-6582

Testing/Troubleshooting
1

Hello there,

I need help with finishing my MB-6582. What i have is:

  • PCB set from smashTV

  • all components hooked up

  • PSU option B

  • all sockets tested (+5, +9, +12, GND)

  • Burn the Bootloader into PIC

  • I did the MIDI Interface Troubleshooting Guide

  • upload testtone_v3b

Than I put a jumper from pin8 to pin27 of SID-Socket but I will get no testtone! I turned on my oscilloscope to measure pin24 & pin 27 form U1_Core1, nothing came out.

Please help me!

Regards

Philipp

Does your PIC work and is it burned correctly?

Does your PIC work and is it burned correctly?

I’m not sure,

I burned the Bootloader with my Burner8p (sprut.de) into the PIC18F4685, put it into “core1” socket in my MB-6582 and start MIOS.

Operating System MIOS8

Board: MBHP_CORE or similar

Core Family: PIC18F

Bootloader is up & running!

after uploading mbsid_testtone_v3c\main.hex

Reading main.hex

Trying to contact the core…

main.hex contains 1220 bytes (5 blocks).

Range 0x00003000-0x000034ff (1280 bytes) - PIC Flash

Upload of 1280 bytes completed after 0.85s (1.47 kb/s)

… so I think my PIC work well, but I don’t know,

I can’t measure any waveform on the pins.

I got it!

It seems to be an error of my PIC-Burner. It lost his calibration an so the PIC will not work for 100%. After recalibrating my burner every thing works well :whistle:

Best regards
