Hi Josh,

Bootargs is constructed by other macros present in the default u-boot configuration.  Take a look at bootcmd, which automatically runs after the timeout.  It runs other commands (mmcargs is one, I think), that do setenv bootargs.  You would add your additional kernel command line arguments to that macro.

I have a Wandboard quad and I would like to change the bootargs in order to choose a different display.  I am building with Yocto Dora branch, kernel 3.0.35_4.0.0 and U-Boot 2013.10.  In this u-boot version I do not see a bootargs variable with printenv.  I would like to add 'video=mxcfb0:dev=lcd,SEIKO-WVGA,if=RGB24'.  How do I properly edit or add bootargs using this kernel and this version of u-boot?

Thank you,
Josh Kurland
