Re: axfs
i don't know if this topic was already a discussion, but i think, if openmoko could change to axfs, i belive, it's a great performance-step. Problems with it: - axfs is read-only, so you'd need to use a setup similar to OpenWRT with a axfs filesystem containing the base system plus a jffs2 filesystem layered on top (using some variant of unionfs). - its main attraction is the XIP feature, but this only works with NOR flash. We do have some NOR flash, but it's only 2MB (IIUC) and it can only be flashed with the debug-board, so the potential benefit is slim and restricted to those users who bought the debug board. Using axfs+jffs2 might be an option, where the main benefit would be to save some space on the flash drive, but currently the 256MB of flash is rarely a significant limitation (especially if you're careful to keep only application in the NAND and put all your data/images/sounds in the microSD card). Actually, the one place I know where the 256MB of flash is a bit short is when installing Debian there, but using axfs+jffs2 with Debian would be a fair bit of extra work and would often defeat the purpose of using Debian in the first place.

AXFS filesystem for NOR
What is the NOR flash used for in Freerunner? I don't know if it is worth it, but i always wanted to have a execution in place memory scheme on my embedded devices. There it is: http://axfs.sourceforge.net/ Only makes sense in NOR (the XIP part). But maybe we can speed up things (and save RAM) by putting some base system stuff in NOR with a XIP scheme? Problem, i have no idea what the NOR part is used for in Freerunners. Maybe it is all not worth talking about. :) PS: I accidentally sent this mail from my other account.

Re: AXFS filesystem for NOR
I was thinking of the NOR flash as a backup if everithing goes wrong. If you flashed the NAND with a new bootloader and it fails you maybe couldn't start the bootloader from NAND anymore. But you always could boot from NOR flash because you couldn't/didn't reflash this bootloader. Maybe i'm totaly wrong about the duty of the NOR flash, but this is what i think of it. It is the life belt if you swim too far out of the NAND flashing sea. :) Ciao, Rainer Tilman Baumann wrote: What is the NOR flash used for in Freerunner?
