Hello,
I own a SL-5600 and want to have swap. (I have gentoo installed and it needs swap for compiling) At the moment I'm using a swapfile mounted over NFS, a relly slow solution and no solution when the PDA isn't docked. So, I thought I might use the internal flash. I have my system installed on a SD-card, which I boot with the help of the rbooot-script. I might need the stuff on mtdblock2 as a rescue system, but mtdblock3 isn't needed for it. So I can make a swappartition out of it and use it. BUT: Flash memory is known to have a limited lifetime, a limited count of write cycles to be exact. (that's why I don't want a swapfile on the SD-card) Is it the same with the internal flash of the poodle? Using it as swap would kill it very soon, I fear. Do you know other possibilitys? Thanks for your thoughts. |

As far as I know the 5500 only has RAM. It has no internal flash.
But that is not true for the 5600. |

It's easy to check: remove the battery for a few hours and see if everything is still there. Internal flash is flash too (duh....), so swapping on it isn't the way to go. I use an SD card for swap on my c700 and that works pretty well, especially with kernel 2.6. |

But the SD-card is flash, too. So you are cutting down it's lifetime?
