Altitude Posted January 3, 2010 Report Share Posted January 3, 2010 (edited) I unfortunately missed the part about not needing to update MIOS for the slave pics in my MB6582 and went ahead and uploaded 1.9g via the thru method. After the reboot, I got CAN errors when trying to clone the app to the slave cores so I figured I borked something uploading MIOS to the slaves. I finally got around to pulling the PICs out to look at what happened and it looks like the 1.9g did upload, I get the title but it immediately goes to two rows of solid bars and what is even stranger, I do NOT get and upload request when I start the pic. I can not upload anything with MIOS studio and it hangs on the reboot cycle. Anyone have any thoughts on what I did wrong or if there is a way to fix short of reloading the bootloader?

TK. Posted January 3, 2010 Report Share Posted January 3, 2010 To get some additional infomations: does MIOS Studio receive the initial upload request during startup with the master core? Best Regards, Thorsten. Quote Link to comment Share on other sites More sharing options...
Altitude Posted January 3, 2010 Author Report Share Posted January 3, 2010 (edited) To get some additional infomations: does MIOS Studio receive the initial upload request during startup with the master core? Best Regards, Thorsten. Nope, nothing is sent at any time from the pic and it never reboots when Studio tells it to. The 00 ID pic didnt have any problems btw. The procedure I followed was to hit the soft thru to the slaves and send a "dumb" upload (sent on different ID channels, one at a time until done) however I dont see that in the manual anymore and there is a note that bidirectional communication is required, which very well may be what the issue is here * Edit, I made a mistake in my first post, the screen says 1.9f not 1.9g so it looks like using the thru method did something to the bootloader and 1.9g did not arrive as I thought. Time for the P18 i guess. Any reason why I should not upload 1.9g and go back to 1.9f for the slaves?

TK. Posted January 3, 2010 Report Share Posted January 3, 2010 Nope, nothing is sent at any time from the pic and it never reboots when Studio tells it to. Then the problem seems to be located somewhere else. There is a trick which forces a reboot without power-cycling the core: tap a cable from ground to pin #1 of the PIC for a short moment - this will reset the core. It would be interesting, if this helps.

Unlikely that this happened, but if you don't want to find out the exact reason for the failure, burning the bootloader makes sense... There is no reason why it doesn't make sense to upload v1.9g Best Regards, Thorsten. Quote Link to comment Share on other sites More sharing options...
Altitude Posted January 3, 2010 Author Report Share Posted January 3, 2010 (edited) Thanks for the help, dusting off the burner now.. Unfortunately, I did this when 1.9g came out and have not really worked on it until now whatever I did will be lost to time..

Altitude Posted January 6, 2010 Author Report Share Posted January 6, 2010 (edited) Ok, Reburned the bootloader and MIOS 1.9g onto the slaves and lo and behold, still CAN bus errors when I am trying to clone and the pics function normally in my test core.. I did upload the app to the slaves individually and that worked fine. Cloning was working fine up until I uploaded 1.9g btw..

tonyn Posted January 13, 2010 Report Share Posted January 13, 2010 (edited) Maybe it's just the app you are uploading with. My cores are version 1.9, and I have had problems uploading syx files. Are you uploading hex or syx files? MiosStudio and Midi-Ox seem to do fine with hex uploads, but have problems, for me at least, with syx files. I finally had to use the Sysexbox app for syx file uploads to the 1.9 cores. It could be that MiosStudio and Midi-Ox are looking for a request or something that isn't syncing with version 1.9 of mios for the syx uploads, or?

I can upload the app just fine to the first core via MIOS studio, it just tanks when I go to clone the app to the other 3 cores. I've had this thing for 3 years almost and never had any problems till now.. Quote Link to comment Share on other sites More sharing options...
