Hi, I've got a little problem with uploading the SID-app. I've got a PIC18F4685 with MIOS 1.9d , and a Core-module from Smash. If I power it on, it boots up, the Display (in 4-bit-mode due to the CAN connection with the slave, who is not connected at this moment.) shows first the MIOS-version, and then "Ready." everything is how it should be. If I connect it to the PC and power it up, I don't get any upload-requests. Neither Midi-OX nor mios-studio recieves anything. I think I didn't swap the MIDI-connections and/or their polarity. (btw.: I think I discovered a small error in the CoreV3-pdf: the Midi-out-port has 2 "M-" there.) Any suggestions to solve this problem? thx, matthias EDIT: I solved this problem, but discovered another problem. I described it below.
