+Larry Posted November 29, 2017 Share Posted November 29, 2017 Right now I'm trying to update my SIO2SD V2.2, and I cannot get the firmware update function to activate. It otherwise works great. I have folder ATARI in the root directory I have the SIO2SD.BIN file in the root directory. But when I press SHIFT + K3, it just swaps D1 and D2 continuously. Are there specific "rules" for upgrading the firmware. That is -- perhaps my hardware cannot upgraded beyond 2.2? Mine is a fairly early version from Pigula (IIRC). Are there specific "rules" for which XEX files that can be used? Such that a 2.2 bin must always use the matching 2.2 xex (etc.)? (seems likely). Can (in general) a V2 be upgraded to V3 bin file -- or is the hardware enough different that it can't be done. I'd like to be able to use one of the xex files that can manipulate all 8 drives instead of just 4. I've found a nice case for my SIO2SD, but if I need to, I'll upgrade to a cased V3. Thanks for any help! -Larry Quote Link to comment Share on other sites More sharing options...
_The Doctor__ Posted November 29, 2017 Share Posted November 29, 2017 (edited) If you have the correct crystal, and you followed the directions and it fails, you will have to add the header and program using a cable... or take the atmega chip and put it an a programmer... The power must be rock solid to the chip, I had one with a bad sio cord that wouldn't operate correctly, wiring up a fresh connector saved it. If you have partially upgraded the firmware you may have to do the shift shift method... as if it were the new firmware...
