Regarding nandwrite issue for huge files ?

[R Arun Kumar]

Hai,

I am able to successfully port the barebox for my custom IMX31 board and
also boot linux on the same.
I am trying to write the uImage and the root.jffs2 file from barebox and
found that even though uImage is written successfully and able to boot from
nand flash also. The nand file write for files more than 3.5 mega size is
not able to write and the barebox loader is hanged.

Please help or suggest what could be the issue ?
