Hey guys! Im completely new to midibox and mios things but i plan to build a daw controller for my studio! so i just soldered a MBHP\_MF\_NG module together and burned the bootloader\_v1\_2b\_pic18f452.hex file via PIC programmer onto my 19F452. The next step would be to enter MIOS Studio (version 2.4.6) and load the firmware of the board via MIDI. I connect the module with my MIDI interface ([klick](http://www.surplustronics.co.nz/products/4863-usb-midi-interface-lead-usb-powered)) the the IN-LED of the MIDI-interface starts blinking -\> i get a signal from the module. In MIOS Studio i get the error message: **No response from MIOS8 or MIOS32 core! Check MIDI IN/OUT connections and Device ID! For debugging see also Help-\>MIDI Troubleshooting** and in the MIDI IN section an endless list of signals appear (everytime the IN-LED of the interface blinks the list updates): **Scanning for MIDI Inputs… [1] USB Midi MIDI Monitor ready.

You need to upload the bootloader through midi first before uploading the application. ---

> Just now, Shuriken said: > > You need to upload the bootloader through midi first before uploading the application. The problem is that I can’t do anything in MIOS Studio, so how do I upload the bootloader? I still get the message: **No response from MIOS8 or MIOS32 core!

Ok, well then there are two options; either the primary bootloader has not been burned correctly or there is a problem with your midi interface. I think this should be a seperate topic though, so i splitted it from the release topic. ---

The MIDI-Interface should work fine, i get a signal from the burned PIC and the MIDI IN status LED of my interface is blinking (recieving information). But this information looks like this: **Scanning for MIDI Inputs… [1] USB Midi MIDI Monitor ready.

Try turning off the Core, select the hex file and press Start in MIOS Studio. Then power on the Core. ---

Have you done a voltage check before you plugged in the PIC and 6N138?  IC5:MCLR(1) - IC5:Vss(12) = 5V IC5:Vdd(11) - IC5:Vss(12) = 5V IC5:Vdd(32) - IC5:Vss(31) = 5V IC9(8) - IC9:(5) = 5V   ---

Your MIDI interface is probably not suitable; MIOS has a rigorous loopback test (?) that won’t properly upload firmware unless the connections are solid.  Check here: [http://www.midibox.org/dokuwiki/doku.php?id=midi\_interface\_blacklist](http://www.midibox.org/dokuwiki/doku.php?id=midi_interface_blacklist) ---
