[U-Boot] Load kernel from JFFS2 / Bad Data CRC

[U-Boot] Load kernel from JFFS2 / Bad Data CRC

[Sophie Bonnouvrier]

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 1000000 uImage

[U-Boot] Load kernel from JFFS2 / Bad Data CRC

[sophie bonnouvrier]

More information : when I compare the file download in ram with fsload and
nand read I have a word of difference ...
If someone have an idea ...
thanks

[U-Boot] Load kernel from JFFS2 / Bad Data CRC

[sophie bonnouvrier]

Ok, I've found my error ....

I don't used FTP in binary mode when I download file in filesystem.

Sorry, for the disruption.

Sophie
