TF530 with Fast RAM from another card
Is there a way (flashing the CPLD, in case) to disable the onboard RAM of the TF530 so that the CPU can be used with Fast RAM from another card?
Re: TF530 with Fast RAM from another card
I think you should be able to just wipe the RAM CPLD on the TF530 to disable the RAM.
A kludge is a workaround or quick-and-dirty solution that is clumsy, inelegant, inefficient, difficult to extend and hard to maintain.

That will kill IDE support.
Sorry no you can’t do this.
EDIT: the latest firmware is compatible with other fastram. Just the autoconfig will clash if the other board is over 4Mb and ZII.

Ah, crap. In my defense I wrote “I think”

Re: TF530 with Fast RAM from another card
Would just say it’s rather (not completely but somewhat) pointless to use the TF530 without it’s fastram because the board inserts wait states such that it’s running at 7Mhz effectively. So all you gain is IDE. It’s no longer an accelerator.

Re: TF530 with Fast RAM from another card
I see your point.
I've tried to get it working with mkl's board, he made a special 4MB-only firmware for me, but I never succeeded. Always black screens.

Re: TF530 with Fast RAM from another card
Start with DiagROM. Does this 4Mb firmware allow for the OS to place the RAM at $600000 ? Because the TF530 grabs the first slot at $200000.
Then figure out if you have the latest TF530 firmware.. older firmware wont work with this kind of fastram at all..
Finally it may just not work at all... with or without the onboard fastram.. but I have already spent a year on this making it work and TBH I dont want to work on it anymore.
The Kipper2k RAM does work and i presume those are very similar timings.

Re: TF530 with Fast RAM from another card
I reported that bit of information to mkl and he came up with a new firmware. I tested it and we have some major improvements!

Although, when I run the memory test, it fails. It fails differently if I run a test of the whole memory...:
... or if I only test the $600000 region:
Other regions test fine. So it seems we're getting closer... Any more hints?
PS: Please ignore my sh*tty video quality.
PS2: Haven't tried diagrom so far, but I can, if that could help.

Re: TF530 with Fast RAM from another card
Diagrom would help.
Which firmware do you have and which TF530 revision/speed

Re: TF530 with Fast RAM from another card
Latest firmware I'm aware of on a rev.2@50MHz built by Viktor.
