Woo! It lives again!

BTW, I do not think the zaurus has a separate ROM.

I'm looking at the 64mbit P2ROM on the schematic right now.

ah, then I stand corrected, thanks! do you have a workshop manual then, or are you looking at hires photos of the PCBs?

I'd be curious to know a bit more about the flash config, whether its got hardware partitioning enabled, any write-locked regions, and what's in each?

Oh, and lest I forget, thanks to everyone again. The zaurus community is a wonderful thing.

If I ever win the lottery I shall pay for a zaurus convention and pay everyone's travel costs to come!

Uh-oh, Wiped My /dev/mtdblock1 Device

I installed Angstrom spitz on my 3100 (which uses the microdrive for most things) and wanted to make use of unused flash and I think I'd committed a massive cockup!

I accidentally formatted /dev/mtdblock1, which I think is the emergency recovery partition.

My Z is alive, running Angstrom OK, so I can put the data back into the partitions. I'm going to keep it powered up on charge so it won't try and reboot!

Can anyone confirm which partitions are which - mtdblock0 to 3, and perhaps let me have the data that should go into the critical ones!

I think you are in big doo-doo.  Angsstrom actually stores the kernel image there.  That device is the 128M flash ram that is mounted on / in 2.4 kernels.  

But you can restore the Sharp rom and start over....

yeah, that's what I had to do...  I should have remembered D+M menu recovery, but I was too busy panicking to think straight!
