Jaguar Audio/Video test software?

[+Mitch]

Here is a version that auto-boots to the controller test. I renamed the diag cart rom to match the EEPROM.

Would this work on Skunk board?

I don't think the skunk has an eeprom, does it?

Rev.4 does, as do the Zaxon ones.  need a tool to flash the serial eeprom, and have to see if it will run as a 16-bit cart though.

In case anyone was wondering what it looks like from the console side when running the diag cart here is a screenshot.

Apologies for the necrobump, but has anyone here ever put this factory diag dump on a "real" cart successfully?  I am trying to make one of these test cartridges.

 

-I have a two chip PCB with socketed EPROM and EEPROM chips that I use for testing.

-Used jag64.exe to split jagdiag5394.j64 into U1 and U2.

-Wrote out the two EPROM chips and the 93C46 using my Minipro.

 

I see am getting a perpetual black screen as described earlier in the post.  I tried both of the settings EEPROM dumps in this thread.  I don't have a serial cable to see if it is doing anything else.  I also tried two different consoles.

 

I have made other carts using a similar procedure, the only difference is that I have never tried to program the 93C46 from a dump before, but I was able to read it back and it seems to be working.

 

Am I missing something?

The 93C46 is a 16-bit wide EEPROM. When read from/written to a binary file, there's no universal standard on which byte order should be used (MSB first or LSB first, aka big-endian or little-endian). So if your programming software has a setting for this (or something like "swap odd and even bytes"), try flipping it and reprogramming the chip to see if it helps.

Thank you.  This was  the correct answer. 

 

In case anyone else runs across this and is using Xgpro, once you have the EEPROM .bin file loaded into the buffer, right click -> Fill/Swap block.  Make sure 16-bits is selected under Swap Byte or Word and hit Swap.
