Passt der Header ID ([“every CoreModule in the MidiBox MidiSystem need his own ID set by the The MIOS bootstrap loader”] => Bootloader/IC Prog) und der MIOS ID im MIOS SysExDump zusammen?
Sendest Du Mios via SysExDump innerhalb von 2 Sekunden nach dem Empfangen des “Request for Upload”?
Ensure that the MIDI interface of your computer is working: loopback the MIDI Out of your PC to the MIDI In of your PC and send any SysEx dump by using the “Send/Receive SysEx” function of MIDI-Ox. The number of sent bytes must match with the number of received bytes. If it doesn’t match, search for a new driver for your MIDI interface/sound card. If not available, you can possibly fix this problem by lowering the Low Level Output Buffer size (normaly set to 2048 ) and by increasing the output delay (normaly set to 0 ms) in the MIDI-Ox SysEx configuration menu
