Hi all,
   I thought I knew just enough to be dangerous with u-boot scripts, usually working backwards from a u-boot printenv to figure out what needs to be in the script.
This time, I have fought this for too long and am hoping that someone will be able to point out what I am doing wrong.

Goal:
   add to mmcargs 'video=mxcfb0:dev=hdmi,1280x720M@60,if=RGB24' so I can use HDMI output from my imx6qsabresd (there is a touchscreen also hooked up but...)
(found the args in https://community.freescale.com/message/319071#319071)
When I do change the environment to add the args, I do boot, but can't do the same with a boot script
I would like to use a boot script so that I don't have to play with the environment when I want to switch devices, just switch cards.

Perhaps someone has a base script I can work from for the imx6qsabresd? I have the nitrogen6x script, but that relies on functions not present on the imx6qsabresd.

Starting with an image that will boot and display to the touchscreen.

What I tried: myscript.txt

setenv videoargs 'video=mxcfb0:dev=hdmi,1280x720M@60,if=RGB24'
setenv mmcargs 'setenv bootargs console=${console},${baudrate} root=${mmcroot} ${videoargs}'
