Hi all,
Excuse my question if it was solved somewhere in forum, but I didn't
found an answer yet (maybe I can't find the right keywords).
I am building the uboot with yocto for imx6 board. I have started with
some freescale defaults,
edited environment for my needs, saved environment etc ... Now I want to
create a custom
"default" boot script, that will do some "heurestics", such as "look if
usb stick is present, then boot from it, else boot from emmc, etc...".
Currently I am storing that script on first partition on emmc and
loading it with ext2load.
But it has drawbacks:
- user should delete that file -> brick
- user should broke entire filesystem -> brick
I want this script to be "embedded" somehow with uboot image (which is
placed outside partition table on device), but I didn't found any doc
how to do that.
Currently I use CONFIG_EXTRA_ENV_SETTINGS for some basic stuffbut it is
unmaintainable for bigger scripts.
Any suggestions?
Thank you.
