I've sent the guy at Micron a mail, hopefully I will have a reply by tomorrow evening.

I suspect it may be possible to edit the player binary, if someone wants to disassemble it and find where they access the ReservedCache variable, and then patch it to be a bigger default number.. or to permit '-' signs..

I actually am working at Micron in Manassas, VA. If your contact doesnt work out let me know maybe I could look around at work and find someone to help us out.

Greetings!

Just in case, I am following through with the alternate order. You can never have too much memory!!!

Got the reply from Micron,
they are out of stock world wide on them.
There's plenty of "MT4LC16M4A7TG-5" in the US, but I didn't find a proper datasheet though I expect it to not be compatible.
There's also a "planned" build of the chip, MT4LC4M16R6TG-5 in the US, due end of July.

On my upgraded Mk2a player (32MB total), the player software seems to make use of at least a few MB of the extra memory for holding the database. But it does not use most of it yet -- need a newer alpha release (from peter or rob) for that to happen.

Suppose, hypothetically speaking, a new alpha release was in the works, and one of the target features was out-of-the-box support for bonus RAM. Rather than duplicating all the effort, it'd seem wise to use the mighty power of the GPL to add the relevant bits of Hijack back into the standard kernel (with full Mark Lord attribution of course). Would I be right in saying that the bonus RAM detection is localised in arch/arm/mm/mm-sa1100.c, include/asm-arm/sa-1100/memory.h, and arch/arm/kernel/setup.c? Or are there some other bits hiding somewhere I've not found? (head-armv.S seems to have been patched and then unpatched).

If, hypothetically, this were to happen, would it be possible for someone to take a look at the memory test code and make it test any additional memory found? It's hardcoded according to hardware release at the moment.

This would greatly facilitate upgrading other peoples' players as only the mainboad would need to be shipped. At the moment disks are needed to soak test the upgrade.

As for the other questions, I'd suggest pinging Mark by email. He's been very quiet here in the past couple of weeks.

He's in the UK this week, with limited access to email.

Ah, of course. It seems to work with just those three files, though. Uh, hypothetically speaking.

Please, please, please, doublecheck that the v394 change gets in there or anyone with 48MB/64MB will end up with a borked empeg and will need to desolder some RAS wires to recover.

Many Hypothetical Thanks.

How does it manage to bork it so badly that the bootrom can't apply a stock upgrade file?

Why would it bork the empeg? The kernel is loaded by the boot loader which does the flash upgrade anyway?

Doh. I'd forgotten about the serial bootloader cause I try to never use it. The problem that HJ v394 fixed is seen as soon as the kernel accesses >32MB, which I'm guessing wouldn't ever occur during a serial bootflash.

Ok, not so serious then. I guess I could rebuild an .upgrade file containing any hypothethical software release so that it had a different kernel and thus avoid RAS pin issues. It would be a pain though as everyone with >32MB would need to do so in order to use any such release.

I'm fairly sure that you have picked up that change anyway - it's been there for a few weeks now.

Hypothetically speaking, it could well be a defensible debating position to assume that any putative forthcoming release might perhaps be based on v394 (in fact 395, but the final patch didn't affect RAM detection).
