This is related to presetting the uboot environment variable rather than having to go in to uboot prompt and changing the environment.
I have built uboot for imx6sx board using the config mx6sxsabresd, I see that the default dtb file used by it is set "imx6sx-sdb", I wanted to change this to "imx6sx-sdb-lcdif1", apart from this I also want to change mmcargs to configure by display driver. how do I do this in buildroot environment?
Thanks for the input.
Hello Arun Kamath,
Uboot performs a detection of the board to select the appropriate device tree. However, you can set the device tree you want to use as part of the boot arguments:
setenv fdt_file <DEVICE TREE>
You can find more details on how to setup the boot arguments for different configurations on the i.MX Linux User’s Guide, which is available as part of the BSP documentation.
I hope this helps!
