XC3N Posted December 14, 2014 Report Share Posted December 14, 2014 (edited) Hi! I wanted to upgrade the Application package in my sammichSID and things went awry =( What I've done: Connect a UM-1EX USB MIDI interface in the Synth Launch MIOS Studio 2.4.6 Browsed to \midibox_sid_v2_043\setup_sammich_sid.hex Hit Start The upload went fine, the synth rebooted but after rebooting it has the following behavior: Synths get powered up, emits a pop, LCD initializes (sometimes displays garbage) A series of beeps is emited Series of beep is played faster The LCD goes on "light show" mode I've seen once the MIOS init screen stating "Launching CS" but it remained there. Synth does not boot up at all, MIOS studio doesn't "see" it either. The only (dumb?) thing I noticed is that I had midi clock running TO the synth while I did the upgrade, possibly inducing data "noise" in the upgrade process? (I'm not too good with sysex) Any help would be appreciated as I fear my sammichSID will require pic reprogramming outside of its shell, which I'm not equiped for x_X Edited December 14, 2014 by XC3N Quote Link to comment Share on other sites More sharing options...
TK. Posted December 15, 2014 Report Share Posted December 15, 2014 Hi, yes, a MIDI clock could disturb the upload. You can recover the device the following way: power-off the sammichSID in MIOS Studio, load the setup_sammich_sid.hex file and press the start button power-on the sammichSID -> upload should start immediately after power-on Best Regards, Thorsten.

XC3N Posted December 16, 2014 Author Report Share Posted December 16, 2014 (edited) Thank you TK, this worked! However I wish this was documented somewhere :s if I had known I could just send the code without an initial "sync" with MIOS I wouldn't have attempted to remove the PIC to try and reprogram it... Which brings me to my next question: I damaged pin 40 (PGD) which I jury rigged with a lot of swearing involved... pardon my lack of knowledge but am I right in assuming the "repair" worked if I was able to reprogram the PIC properly? (my shoddy repair: http://bit.ly/1wbBOfn) Thank again! It's quite a relief to see my sammichSID working again and I did learn quite a lot! hehe Francis // XC3N Edited December 16, 2014 by XC3N Quote Link to comment Share on other sites More sharing options...
TK. Posted December 16, 2014 Report Share Posted December 16, 2014 Great! :) It's documented here: http://www.ucapps.de/mios_bootstrap_newbies.html Applications can always be uploaded - if not, there is an error in the application which prevents this, but in this case you could just use the primary loader in order to refresh the code under safe conditions (just push the start button in MIOS Studio, and power-off/power-on the core or trigger the external reset by tipping ground to pin #1 of the PIC). You can check if the pin #40 repair works by connecting the LCD, because Pin #40 is the D7 dataline to the LCD Best Regards, Thorsten.

XC3N Posted December 17, 2014 Author Report Share Posted December 17, 2014 (edited) oh awesome then, the synth is working fine so should be ok until the solder breaks haha (and damn my poor RTFM skills!) Thanks TK Edited December 17, 2014 by XC3N Quote Link to comment Share on other sites More sharing options...
