From this release, PetaLinux supports using all Yocto variables in petalinux-config, for example, TMPDIR. To use the shell
variables, you need to export the shell variable to
BB_ENV_PASSTHROUGH_ADDITIONS. You cannot use normal shell
variables directly to align with Yocto like the previous versions.
export BB_ENV_PASSTHROUGH_ADDITIONS="$BB_ENV_PASSTHROUGH_ADDITIONS BB_USERNAME"
Note: In the previous example, the host machine exports the user
environment variable by
default.
export BB_USERNAME=$(whoami)
exportBB_ENV_PASSTHROUGH_ADDITIONS="$BB_ENV_PASSTHROUGH_ADDITIONS BB_USERNAME"
Note: In the previous example, BB_USERNAME is a new environment variable
defined and exported to the BB_ENV_PASSTHROUGH_ADDITIONS Yocto
variable. After it is exported to BB_ENV_PASSTHROUGH_ADDITIONS,
you can use BB_USERNAME for the petalinux-config options
