question about the u-boot-socfpga-env recipe

[tommes0815]

Hi,

I am starting to work with the Arria 10 SoC devkit and tried to become familiar with the yocto flow for the ARM SoC. I ran the build flow for the gsrd as described on rocketboards.org. I could successfully build everything and it is running on the devkit.

As a next step, I played around with your recipes and tried different things like changing the u-boot environment adding a boot script... I stumbled trying to change/use the u-boot-socfpga-env recipe. As far as I understand it, it should set the initial u-boot environment according to the files in meta-intel-fpga-refdes/recipes-bsp/u-boot/env/ . Hence, when I change, for example, the bootdelay variable in arria10-socdk_u-boot-env.txt it should start with the new value. Somehow that does not work. The change is reflected in the generated files in the deploy directory (like arria10-gsrd-rootfs/tmp/deploy/images/arria10/uboot.env) but not in the final image.

I have studied also the u-boot documentation. How do you actually set the u-boot environment in the u-boot-socfpga-env recipe, how would it become the default environment during the build?
