Error in flashing filesystem into nand flash using u-boot

Hello

I want to flash filesystem into nand flash.

I have build jffs2 filesystem just as the <TI816X-PSP-04.00.00.10-U-Boot.pdf>said.

But when I flash it into nand, it failed.

Here is what it shows.

So what can I do then?

Thanks.

I have found the reason that leads to the problem.

Just because the filesystem is bigger than 200MB which is the limitation of the nand flash(mentioned in the TI816X-PSP-04.00.00.10-U-Boot.pdf filesystem start and end ).

But after setting the args I still can't start up the 8168evm.

Here is what I get in the console.
