Troubleshooting BSP Integration
U-Boot finds its initial configuration file by looping through the partitions in order and searching for
uEnv.txt first in
/, then in
/boot/. If U-Boot isn’t loading the correct initial file, you should check the partitions layout, and see if there’s a vendor-provided
uEnv.txt in a partition that comes physically before the one you’ve placed the OSTree initial
Values specified in
local.conf have the highest priority in a Yocto build. Most vendors provide a setup script for the build environment that also generates a
local.conf with many values pre-populated. In some cases, those values can conflict with changes that the meta-updater makes.
For the LS1043ARDB, the environment setup script added a line to the
local.conf that overrode the
INITRAMFS_IMAGE value. To fix this, you need to specify the correct value in your
local.conf when you build:
INITRAMFS_IMAGE = "initramfs-ostree-image"
Building an integration with a new board involves dealing with several different systems. See the following links for more information on this:
Yocto Mega Manual, v2.6: The Yocto Mega Manual is a concatenation of all the various other reference manuals; it’s usually better to use the individual manuals if you know what you’re looking for. In particular, these three are the most frequently used in the BSP development domain:
