FantomXR Posted April 7, 2020 Report Posted April 7, 2020 Hey people, I have a problem and I hope you can help me. I've created a PCB based on MF_NG. Schematic and layout see here: I have a PicKit3 to program the 18F4520. I use the MBLAP X to flash the bootstrap to the PIC. The programming seems to work fine. I don't get any error messages. As stated on the MIOS Troubleshooting page there seems to be a problem with the ID when working with MBLAP. See here (bottom):http://ucapps.de/howto_debug_midi.html So I also flashed the bootstrap-workaround which also ran fine. If I now connect the MF_NG via MIDI to a core, I get this error message: [395386.494] [MIOS32_MIDI_Receive_Handler] Timeout on port 0x20 Do you know what that could cause?! Best, Chris
FantomXR Posted April 7, 2020 Author Report Posted April 7, 2020 I've just noticed, I've used the PIC18F4520 instead of PIC18F452. Could that be the problem?

Not expert at all for the question, but I find this: http://ww1.microchip.com/downloads/en/DeviceDoc/39647a.pdf I suspect it deserve a read Best Zam

I built a Midibox Midi Monitor a while ago and I used a 18F452 as per shematic, the bootloader flashed no problem. http://ucapps.de/mbhp/mbhp_core_v3.pdf I did get the wrong PIC at first a 18F4520, not 18F452
FantomXR Posted April 8, 2020 Author Report Posted April 8, 2020 Thanks! I'll order a 452 and try again... Thanks, Chris
FantomXR Posted April 29, 2020 Author Report Posted April 29, 2020 It works great with the correct PIC18F452 ;-)
