How to update u-boot from Linux

Hi
I am using the ccimx6ul and DEY.
I can update u-boot from u-boot itself (using the “update” command). But when I try to flash it from linux (using flash_eraseall and nandwrite), the system doesn’t boot.

I checked the source code of the “update” command in u-boot and it seems to be using some special tricks to update the bootloader.

Is there an easy way to do the same from Linux?

thanks
