Hi NXP guys,
I'm using i.MX6ULL with nand flash.
I have a question about upgrade from sdcard boot.
Since I boot from sdcard, how can I upgrade the nand?
I'm concerning about:
1. How can I build the upgrade image for nand? Is the wic image that I built with nand u-boot configure?
2. How can I upgrade nand since I boot from sdcard?

Solved! Go to Solution.
Thanks guy,
I've find the solution.
Just refer to the uuu.auto script and follow its step, that's a way to upgrade firmware in flash.
The key point is: we must use kobs-ng to upgrade the boot, and take attention to the flag '-x'.

pls refer to the document as below:
Hi joanxie,
It seems that you have misunderstood my question.
I'm querying the sdcard upgrade.
Since now I find a way to upgrade nand flash data as the uuu.auto does.
But unfortunately, after I flash the uboot partition with "kobs-ng init $pad -v --chip_0_device_path=/dev/mtd${nandboot} xxx", the device can not boot up.
Is there anything that I missed?
