Qi makes all the partitions in nand useless, could these be put together to allow one larger rootfs? There is config, kernel and splash which could be merged into the rootfs partition. It should also be possible to shrink the the partition of u-boot. If this is a suitable suggestion is someone able to write a short HOWTO how to accomplish that for GTA01 and GTA02?

will it boot jffs2 on flash ?

--kd8ikt

Install Qi on you NAND flash. You can still boot whatever distro you've got on internal flash using the NOR bootloader.from here So I think it should still be able to do jffs2, but I'm not sure. Bram

dmesg output

With `uname -a` = "Linux om-gta02 2.6.24 #1 PREEMPT Tue Dec 2 15:02:59 CST 2008 armv4tl unknown", dmesg outputs s3c2440 on GTA02 Revision: 0360. qi-s3c2442-master works fine on it.

post-init booting stuff is faster?

"Surprisingly, the later segments of booting (desktop) were also noticeably faster than with uBoot"

How many times was this experiment done, by how many different people? For empirical stuff, more data is invariably better. Sm 22:04, 7 January 2009 (UTC)

large uSD cards support

How large does "large uSD cards support" mean? Is there any accurate information available on this?
