Moduku Posted January 19, 2011 Report Share Posted January 19, 2011 (edited) 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.

nILS Posted January 19, 2011 Report Share Posted January 19, 2011 What midi interface are you using? Is it on the black- or whitelist? Quote Link to comment Share on other sites More sharing options...
Moduku Posted January 19, 2011 Author Report Share Posted January 19, 2011 It's an E-MU's Xmidi 1x1 Tab. Under Windows 7 64. Not in the black list. Should I add it there? Thanks Quote Link to comment Share on other sites More sharing options...
nILS Posted January 19, 2011 Report Share Posted January 19, 2011 Uploading mb6582.hex to PIC0 takes forever ( >5000s ). Once finished MIOS 1.9g reboots and LCD stands in READY. 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. Quote Link to comment Share on other sites More sharing options...
Moduku Posted January 19, 2011 Author Report Share Posted January 19, 2011 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.

nILS Posted January 19, 2011 Report Share Posted January 19, 2011 Did you source the parts yourself or buy a kit? Help us out with some more details here, please. Quote Link to comment Share on other sites More sharing options...
Astazou Posted January 19, 2011 Report Share Posted January 19, 2011 It's an E-MU's Xmidi 1x1 Tab. Under Windows 7 64. Did you install the E-MU Windows driver ? I can't remember where I found (very recently) that the Windows USB-Midi generic driver is broken when you want to do SYSEX transfers, and that the XMidi works fine when the E-MU drivers are installed.

Moduku Posted January 19, 2011 Author Report Share Posted January 19, 2011 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. Quote Link to comment Share on other sites More sharing options...
Moduku Posted January 19, 2011 Author Report Share Posted January 19, 2011 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! Quote Link to comment Share on other sites More sharing options...
nILS Posted January 20, 2011 Report Share Posted January 20, 2011 Glad you got it working! :frantics: Quote Link to comment Share on other sites More sharing options...
