hello,
I try to load from JFFS2 filesystem , the kernel,rootfs and DTB. and I
have bad data CRC error on my file.
Have you any idea of the reason ?
I try to copy several kernel image in the filesystem i've got the same
error, also with rootfs.
I've no problem with raw file and using nand read in other MTD with
the same kernel,rootfs, dtb.

environnement :
- u-boot 2013 from SDK freescale 1.4
- linux 3.8.13 from SDK freescale 1.4
- custom board based on P2020
STEP 1
- In Linux mount JFFS2 file system and copy kernel, rootfs and DTB.
STEP 2
- In U-boot
fsload 100 uImage
