MB-6582 base pcb - Issues **FIXED**

10 posts in this topic

Guys I need a hand troubleshooting my MB6582 base pcb.

I have done the suggested voltage and continuity tests in Wilba's PCB build guide and everything seems fine BUT:

Uploading mb6582.hex to PIC0 takes forever ( >5000s ). Once finished MIOS 1.9g reboots and LCD stands in READY.

I see no errors of any kind on MIOS studio during the upload.

This is with PSU option A. R80 is in place.

Voltage readings without SIDs connected are as follows:

J3 : 5.16v

J25: 12.55v

C12: 8.97v

J1/2_SID1: 8.96v

SIDs: 8.96v

Cores: 5.15v

Also uploaded testtone to PIC0, no sound.

Any suggestions on where to look for what might be causing the slow transfer rates?

Thanks in advance.

It's an E-MU's Xmidi 1x1 Tab. Under Windows 7 64.

Not in the black list. Should I add it there?

Thanks

Which means the upload didn't work... Have you uploaded MIOS? If so, how long did that take? If it takes that long, there's usually a problem somewhere that and you cannot really rely on the upload having worked.

Ok I tried re-uploading MIOS. Same transfer rates ( 0.02 Kb/s ). Took 835s. During upload LCD read "Rebooting MIOS". Once upload was completed, LCD showed Boot screen and then READY.

Uploaded to PIC1 too with the same results as PIC0.

I have also updated the midi interface drivers but it didn't help.

Did you source the parts yourself or buy a kit? Help us out with some more details here, please.

Parts are from SmashTV's kit. I have used both the generic and EMU's drivers with the same result.

I will try to get to test with a different MIDI interface to rule that out and report back.

Thank you both for your help.

Good news. I tested with a different interface (M-Audio Midisport 2x2 ) and it worked right off the bat.

Updated white/black lists based on my experience.

Thanks everyone!
