Warning - I don't know what it is, but there are some specific config changes you have to make to a card to downgrade from 3.5.x.  I think someone said something about turning them into doorstops if you do this wrong.
 
I'd recommend re-uploading the 3.5.x first.
 
Also - 3.5.12 is the devil - you should go 3.5.105 or 3.5.109.

Subject: [USR-TC] hd020019.dmf

I tried upgrading from hd020019.dmf on a HiPerDSP to hd030512.dmf.  Now the card doesn't work at all.  I want to revert back to the hd020019.dmf but I can't find my file.  Can someone email me this file?

Thanks.
