[U-Boot] How to write jffs2 image to spi nor flash?

[Axel Lin]

Hi list,

I use "sf erase" + "sf write" commands to write root image to spi nor flash.
It works for writing a ext2 image.
However, if I use the same commands to write a jffs2 image I got a lot
of "Magic bitmask 0x1985 not found at..." messages and
"jffs2: inflate returned -3".

jffs2: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x0012f780: 0x4bbb instead
jffs2: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x0012f784: 0x50f2 instead
jffs2: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x0012f788: 0x4230 instead
jffs2: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x0012f78c: 0x76ac instead
jffs2: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x0012f790: 0x439c instead
jffs2: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x0012f794: 0xd9b9 instead
jffs2: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x0012f798: 0x73d3 instead
jffs2: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x0012f79c: 0x5758 instead
jffs2: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x0012f7a0: 0x1b47 instead
jffs2: jffs2_scan_eraseblock(): Magic bitmask 0x1985 not found at 0x0012f7a4: 0xf908 instead
jffs2: Further such events for this erase block will not be printed

So how to correctly write a jffs2 image to spi nor flash in u-boot?

Thanks,
Axel
