Flash Upgrade

[guylhem]

Hello

Since I'm quite close to actually upgrading the SL6000 flash, I'm wondering if anyone would be interested in a simpad flash upgrade?

I'd need some help - preferably from someone with a JTAG'ed simpad :-)

Mine is JTAGed (a small problem with the bootloader some time back), what kind of help would you need?

Hello

Well I'd be interested in a simple experiment - removing the J3 strataflash (16 Mb per chip) and replacing it by greater chips (say min 32 Mb each, or even 128 each !) to boost internal storage.

After that, a new bootloader would have to be installed by JTAG. If you feel like trying I can check the chip reference. Finding/soldering the chips could be troublesome however.

I was afraid it might be something like that... I think my soldering skills are very rusty by now. Just inserting the jtag header I almost destroyed the simpad, as one track jumped out. Luckily I managed to solder it into place at both ends. So I won't be able to help you much here, at least not until I manage to buy a new soldering station and practice a lot more...

Keep in mind that the flash chips in the 6K are NAND, and StrataFlash is NOR, so you can't use the same chips as in the 6K upgrade.

oops. forgot again. would you by pure chance have some spare nor chips?

I haven't had any spare in months. Not sure where to buy them by themselves, but about 90% of the newer Pocket PCs use StrataFlash, so you could pick up a broken screen Pocket PC on eBay and rip the chips out. Most PPCs use two chips for flash, so picking up a PPC with 64MB flash should yeild two 32MB chips.
