Trouble Uploading MIOS

MIDIbox SID
1

Hi,

I am currently working on getting the MIOS setup on my CORE and am having some trouble.  I am using one of SmashTV’s boards. I got it a couple years ago. The PIC is 18F452.  Here was my procedure.

Upload the upgrade .hex.  Worked fine.

Display on the LCD was just the single line of blocks.  Could not get the READY text to show.

Upload the LCD Test application. Worked fine. Tested ok.  Still could not get the READY text to show or any of the LCD Test Application readouts.

Thinking that perhaps it was the MIOS somehow, I tried to upload the MIOS without previous version .hex

Got errors:

Starting upload of update_without_installed_mios.hex

Hex file contains code in MIOS range, forcing reboot!

Received error code 01: Less bytes than expected have been received

This was an expected error - please ignore!

Upload process complete

Not sure about this error but it seems significant.  Also, cannot figure out the LCD.  The LCD seems like it is in fine shape as it gets power and the measurements are ok.  My first priority is getting the latest MIOS installed correctly. Any ideas?

Thanks.

Sounds a bit like you’re uploading a MIOS version that’s meant for a different PIC type?

S

Oh, and btw you do know that you can’t use the 452 PIC for SID V2?

4

Are you saying that v1.9 (latest available MIOS) is not supported for the PIC18F452?  If so, is there a place where old versions of MIOS are kept where I can get the latest version that supports the PIC18F452?  I understand that the PIC18F452 is not supported anymore though but I would like to get something working before I go out and buy more PIC’s, ya know.

Thanks!!! :slight_smile:

5

Oh and I am still working on the version previous to v2.  I took a hiatus from the project for a while (~1 year).  :stuck_out_tongue:

MIOS 1.9 will run on the 452.

mbSID v2 won’t.

mbSID v1.7303b will.

Make sure you upload the .hex file in the “pic18f452” folder of the MIOS download.

Hi!  Thanks for the replies.  We  I got MIOS uploaded just fine today.  However I am not getting the READY screen when I power up.  All I get is the single line of blocks on the LCD.  I have it wired properly (AFAIK).  Link to the datasheet: http://www.shopeio.com/inventory/pdf/AMC2002C.pdf

Any other thoughts?  I’ll retry the LCD tests over the weekend, probably Sunday and return with any results.

Thanks again for the noobie assistance.

no data on your LCD?

that’s pretty odd. especially if the LCD test was already fine.

how do you have it connected? Is the ribbon cable soldered directly to the pins? If so, make sure a single wire didn’t fray and is shorting to another pin someplace. I seem to remember something like this happening to me.

try shutting it off, start the upload in “smart mode”, and then turn it on to re upload the file.

I think I remember having to do this several times to get mine to work when I thought I fried it at first.

Success!  After cleaning up some questionable solder points and re-burning the MIOS, the LCD has displayed READY.  Thanks so much for your help.

Thanks t_xen,

I also wanted to thank you for a previous post of yours that was the final piece of advise I needed to get some sound out of my chip!  It was about the interconnections between the SID and CORE for Smash’s boards.  The labeling threw me off but your thread (and especially the replies) totally rocked!
