How To Use Xd Card In Gp32!

ok even if it did work, you still can't go above 128mb so whats the point?

The point is if you had some xD because you used to be a photographer until you got a gp32!!

They may also be more reliable than SMC`s too. ;)

True but from where i looked they where more expensive unfortunetly. :(

Is this true ? Does an xd card exist > 128mb that works at 3.3v ? If so it may be possible to have bigger storage cards on GP32

I thought the 3.3v was the limiting factor for Smartmedia not the memory card size.

jup you cant go higher because of the gp32 bios... And the 3.3V
and i dont think someone will change this... if its even possible

All XD´s are 3.3V.
But voltage is not everything, the data structure on cards > 128 MB is different to the others. also the problem is not just BIOS related, the GP32 SDK´s don´t support it, so no existing program would work without being recompiled in a SDK that does not (and won´t ever) exist.

And for what exactly do you need such big cards? Even 2h movies can be encoded to fit on 128MB (in high quality), it just takes a bit af time and knowledge.
(you can have my .vcf´s if intrested)

theres stack of reason, all too complicated to be understood by non-coders.

afaik, GPLinux could be the only way to alter this.

I never said I wasn't a coder (I might not be a very good one any more due to lack of practice but as an engineer I can still appreciate what might be needed)

I still think the bios could be patched to access more memory as it is acting as gateway to the memory hardware - I mean if a digital camera can access it then a GP32 can.

There is no hardware limit here that I can see- the address lines are the same, the voltage is the same.

If the bios is currently so written that it implements FAT only up to 128Mb then it could be rewritten couldn't it ?

Very little software would be affected as it will mostly be using calls to file read / write commands in an API rather than setting up address registers and writing byte by byte. If bios support were added would this not be transparent?

This is an interesting update to the 256MB 5v Smartmedia debate last year.

Never say never - everything is possible for an engineer - it will just be delayed and over budget

;)

Try reading them yourself again - they all have the same pointless nay sayers saying it is impossible.

First it was the >128Mb = 5v rubbish when you can see 3.3v XD's are available.

Then it was no bios support and to paraphrase because I can't be bothered to read the ill informed post again ' the transistors are all in a different place so it would get confused'

That's nearly as funny as my friend going to a hi fi shop to buy some nice thick oxygen free speaker cable and being told by the assistant that the sound would "get lost in the wires" and to buy bell wire instead. My mate offered to invite him round to help look for the sound if it did get lost

I repeat my question - if a camera can read > 128Mb what stops the GP32 bios from being patched to do the same now the harware is available at 3.3v

It would seem it was limited to 128Mb for the 5v reason.

BTW If you don't know the answer don't answer the post. The question is fine it is the poor answers that are annoying.

Why don`t you ask Gamepark, After all they designed and built it, So who better to ask ?.

We have and had a fair few talented people a passing through this community, Both coders and electronic hobbyists who have modded and pushed the standard GP32 way past its stock potential.

32-64mb ram upgrade.
overclocking it way past its default 133mhz through modding, Up to 256mhz so far.
GPLinux giving the potential for mass storage devices etc though usb.

Are just a few of them.

So, After 3-4 years and getting this much achieved so far, I pretty sure if it was practical or even possible, Someone would have at least attempted it by now.

It certainly is an interesting possibility. Also, people who don't really know whether or not it's possible should NOT sit here and say it's not possible. Difficult and complicated, maybe, but I sincerely doubt it's impossible. I think we should give more credit to the incredibly talented and innovative people we have in this community.
