I need to mount a jffs2 partition in a bootloader. I tried u-boot that support jffs2, but it is very slow (2 minutes for mounting a 64MB partition). Do you know if there are other (fast) implemenation of jffs2 suitable for a bootloader ?
Not sure about any existing "fast" implementation, but mounting a JFFS2 partition is about scanning whole partition. You may optimize some thing, but you have to scan anyway.
Well u-boot implementation is very slow. For 64MB partition : 2 minutes for u-boot
This really is slow. 64MB isn't that big and shouldn't take that long to mount.
and 11 s for linux (3s with summary).
So it can be done better.
Did you think about improving the performance in U-Boot? If so, please let's move this discussion to the u-boot-users mailing list.
Somebody already try something for u-boot jffs2 [1], but is doesn't seem to work (don't compile). He didn't receive any report, so u-boot jffs2 code seems unmaintained.
Thanks.
BTW: What cpu at what speed are you using?
an arm9 @240 Mhz.
