update system on imx6ull

[barry_chen]

We want use sdcard update system ,linux kernel,rootfs, like Android.

now ,we use nand on imx6ull. That means ,update NAND flash with external sdcard.

so,How to do ?

[barry_chen]

thanks for your help.

I may write a script following ucl2.xml  on my storable sdcard.But,I'll try it. Because according to point 5 from blow picture.we know it was running uboot_mfg,and had host PC. but now ,our application scenario have not PC ,and using sdcard update nand flash . In other words and last, according to ucl2.xml, I know how to write shell script when Updater state ,but not when BootStrap state.

mfg tool is using small linux image which executes (using ucl2.xml) standard linux commands

which may be run when using linux with sd, no need for PC.
