I’m trying to get MIOS 1.8 uploaded to my new core. I am using MIOS studio, i constantly have MIDI I/O activity, I can upload it, and I recieve the “Upload process complete” at the end, however it doesn’t reboot automatically, nor do I see the Ready on my LCD!
What is wrong!?
Is there any message during the upload of MIOS which informs you about a checksum error?
How many messages do you see? (maybe just copy&paste the whole log here)
Best Regards, Thorsten.

Upload process complete"
I also keep recieving Timestamp messeges every two seconds in my IN monitor, even after the upload complete. IIRC, there is supposed to be a reboot and then only two such messages should appear.
Also I remember reading somehwere that the MIOS upload via MIDI should take 9 seconds. Mine takes longer…
Any ideas?!
I can see three things:
- you computer receives an upload request (MIDI Out of the core is working)
- your core never response to a upload block (MIDI In of the core propably not working, or a problem with the MIDI Out of your computer)
- you’ve disabled the “use feedback from core” option of MIOS Studio, therefore you get a “Upload process complete” message - in this mode MIOS Studio doesn’t check if your core has ever received the data correctly, therefore it says “complete”
Proposals:
- troubleshoot your MIDI In port -> see http://www.ucapps.de/howto_debug_midi.html
(in most cases, just only the two connections to the MIDI In jack are swapped…)
- don’t forget to enable the feedback option of MIOS Studio again, because without it can be dangerous
Best Regards, Thorsten.
haha woops, I didn’t fool around with the default settings in MIOS studio. The feedback feature was disabled by default. I will try again after lunch.
Thanks a lot man I will let you know what happens 
It turns out that the Feedback feature unfortunately WAS enabled… which means that the problem lies elsewhere.
What leads you to believe that " your core never response to a upload block (MIDI In of the core propably not working, or a problem with the MIDI Out of your computer)"? What part of my screenshot or LOG brought you to that conclusion?

the core should send the checksum, but it doesn’t. This is visible in the log, as well as in the MIDI in monitor.

Just follow the MIDI troubleshooting guide, it really helps!
Best Regards, Thorsten.
HOORAY!!!
It works! Don’t laugh, but my optocoupler was upside down, luckily no damage was done! It works, I got the Checksum Recieved after each block was recieved as well as the reboot at the end. Also, the whole upload process was faster, definitely 9 seconds. Anyhow, now i have to debug the LCD, the characters are a little awkward (though sometimes amusing 
My unit is “Beady” hehehehehe).
Thanks for your help TK. I read the MIDI Troubleshooting page thoroughly and performed many of the checks that were mentionned on there It will definitely be a reference for me later on!
EDIT: Fixed my LCD problem too! There was a short between two pins Damn a lot of progress was made today!

You haven’t progressed until you’ve “smelled” an LED. (a good day here as well :))
George
Burnt LED’s and resistors were among the highlights of my college days I wouldn’t do that at home I just installed a Febreeze Noticeables air freshner in here haha
