as stated before I am a complete noob to not just midibox but electronics in general, so be gentle!
So I have just finished building my sammichSID including voltage checks, and have gotten as far as the firmware upload and when I hit "Query" in MIOS I get a "No Response" message. I have tried all steps in: http://www.ucapps.de...debug_midi.html and cannot get the loopback to work. I also tried doing the loop back from JMO and JMI and still nothing.
I do get a download request when I power on the unit and a "Ready" message on the screen.
I have posted pics from every angle I could see being relevant, in case some-one notices a bad solder joint. Any and all ideas are welcome.
