Do I have the only 128mb TF536 in existence?

Yes, I think I do

[PhilC]

I think I'd better say a big thank you to @agranlund for working out how to get 128mb up and running on the ST

[JezC]

Possibly the only other thing to add is that I still haven't got the settings right to successfully run any programs in FastRAM, so 64 or 128 is not an issue until I sort that out.

Which RAM have you used @PhilC ?

Might be handy for the second H4...

[PhilC]

@JezC I think this was the ram I used


INTEGRATED SILICON SOLUTION (ISSI) IS42S16320D-7TLI DRAM, SDR, 512 Mbit, 32M x 16bit, 143 MHz, TSOP-II, 54 Pins

About £12 a chip inc vat.

Have you been using prgflags.tos to set the fastram flags? Oh and you may need to flash the latest firmware with the 64mb fix.

- Nice!

Not all heroes wear capes, but maybe @agranlund actually does?

Well I technically have a 128mb TF536, but it only functions as 64MB.
I should maybe swap out the ram, I dont hold much hope in having it working fully now.

@EzdineG I think @agranlund may actually be a secret cape wearer

@PhilC Thanks for the info on the RAM - I think we use a similar part on one of our designs so will check with our preferred silicon disti to see if they are available from them or not.

I have a prgflags.prg that I've tried to use...but have not seen any real difference in the Gembench figures...assuming I'm using it correctly, of course!

There's a file selector so I just set all the flags to the left of the file list...but don't know how to check for sure whether it actually did anything (it was saying file was read-only even though the info on the desktop said it was writeable)...

Won't get chance today but maybe later this week I'll trawl fro a maual/guide to using it & see what I might be doing wrong...

If I need to re-program the CPLD as well then I guess I'd better work out how to use one of my RasPi boards to do it at some point.

Another potential problem is that I've only got a Gotek connected & working so far...not yet managed to get a CF working on the IDE on the TF536 (I think I need a cable to connect between the TF and the CF adaptor board)...

[PhilC]

@JezC I use a cable and cf adaptor from the exxos store. Ill make a simple CF card image soon with stuff on to help you and others get going if that useful?
