you have very few memory available.

you should use the 4m cfi flash first.

spansion was previously a joint venture of amd and fujitsu.

[* ] support for amd/fujitsu flash chips

you can use it as a jffs2 drive.

you can mount it as rootfs, with kernel command line "root=/dev/mtdblock0", and disable initramfs. this will save some memory usage.

there is new option,

in kernel config for higher than 2.6.11,

general setup -->

[*] configure standard kernel features (for small systems) --->

[ ] enable full-sized data structures for core

no in this option will reduce kernel data structure size.

using sd is ok, but it is slow.

using usb disk on isp1362 ? working ?

Yes, follow point8 about cfi-flash.

1. use initramfs, test until jffs2 works.

2. cp -a some dirs from / to jffs2 mount point to build the rootfs.

note some other dirs should be empty, just mkdir of them, eg, /proc /sys .. , look at ~/rootfs .

3. in kernel config, set initramfs path to empty.

() Initramfs source file(s)
