[meta-freescale] Page allocation error on bulk data transfer

[Abdul Ahad]

Hi,

I am trying to do Bulk data transfer test with yocto file system, 
running on i.mx6 dual-lite board with 512MB RAM.The file size is just 
500MB.I ran the test for 24hrs but i am getting following error in the 
terminal.

cp: page allocation failure: order:0, mode:0x200020

Is there any way to prevent the page allocation error.
I have tried the work around specified in sabresd Linux release notes, 
but with out any success.The work around suggested to run the below 
command "echo1 > /proc/sys/vm/drop_caches".

Thank you,
Regards,
Abdul Ahad
