matyt Posted January 19, 2009 Report Share Posted January 19, 2009 I've successfully burned the MIOS, and the change id app (previous topic), via Serial Port.today i've tried to upload an app via midi, and MIOS studio tells me this..

ultra Posted January 19, 2009 Report Share Posted January 19, 2009 try setting mios studio to wait for an upload request, then power on the midibox. Quote Link to comment Share on other sites More sharing options...
matyt Posted January 19, 2009 Author Report Share Posted January 19, 2009 Already done...... as you can see in the screenshot i've selected the option "wait for upload request" Quote Link to comment Share on other sites More sharing options...
slumgud Posted January 20, 2009 Report Share Posted January 20, 2009 Im stuck at the exact same problem. I am pretty sure that in my case the error is a malfunctioning octocoupler. I used these two links to diagnose.http://www.ucapps.de/mbhp/mbhp_core_midiin_debug.gifhttp://www.ucapps.de/howtodebug/mbhp_core_extract_out_led.gifHope this helps.

stryd_one Posted January 20, 2009 Report Share Posted January 20, 2009 I'm hesitant to help you matyt, because last time you asked for my help, I gave you the answer, and then two days later you posted here asking the same question, and got the same answer (about using the change id app via com, or re-burning the pic). It seemed that you hadn't listened, so helping you was a waste of my effort..... But I'll try again anyway.Looks like the core is endlessly rebooting.... First things first, pull the chips and check your voltages, just to be sure that further tests won't fry it. We'll do some more tests after you have confirmed that.In response to slumgud... those images are part of the midi troubleshooting guide on ucapps, and you should follow that whole procedure, not just these two images.It's very unlikely that a broken opto will cause endless upload requests like in your screenshot, It would be slightly different: With a broken opto, and only the bootloader, but no MIOS installed, then the core will send an upload request every two seconds. It will never receive the uploaded data (due to the broken opto) so it will continue to send an upload request every two seconds, even if you are already uploading.In your screenshot, it is requesting an upload far more frequently than every 2 seconds. That indicates that the core is actually rebooting. I'm not convinced that this is really "the exact same problem".Sideline note: This is why it's important to paste logs - small differences in the logs can tell us quite a lot! (screenshots like you did are also OK but text is preferable as it is easier to paste and easier to manipulate) Quote Link to comment Share on other sites More sharing options...
slumgud Posted January 20, 2009 Report Share Posted January 20, 2009 seems like I jumped to conclusions there... Quote Link to comment Share on other sites More sharing options...
stryd_one Posted January 20, 2009 Report Share Posted January 20, 2009 Maybe, maybe not... It's not possible to tell because I don't have all the logs and test results. It's just a guess ;) Quote Link to comment Share on other sites More sharing options...
matyt Posted January 20, 2009 Author Report Share Posted January 20, 2009 I beg your pardon stryd_one, I should have listened to your advice..... SorryBTW, i've checked voltages, and seems they are ok....I get about 5.07 volts at every point on the MIDI troubleshooting, so i think can be ok....

stryd_one Posted January 20, 2009 Report Share Posted January 20, 2009 Well... you should be doing the core voltage test. The midi troubleshooting is a different process. If the voltages are OK, and you don't find any short circuits in the midi circuitry on the core, then try the midi troubleshooting and paste your results here... we'll get it :) Quote Link to comment Share on other sites More sharing options...
