However, the do_deploy_append defined in linux-dtb.inc # assumes that it is being run in the ${S} directory. A patch is # being submitted to fix this issue by either changing the do_deploy # in the kernel.bbclass to do "cd -" as the last step or to add # "cd ${S}" as the first line of do_deploy in linux-dtb.inc and this # function can be removed once that change is available. # If the function is not placed BEFORE the require then the change # directory is not appended before the linux-dtb.inc changes. do_deploy_append() { cd ${S} } require recipes-kernel/linux/linux-dtb.inc require recipes-kernel/linux/setup-defconfig.inc # Stage the power management firmware before building the kernel # for ti33x SOC_FAMILY devices DEPENDS_ti33x += "am33x-cm3" # Default is to package all dts files for ti33x devices unless building # for the specific beaglebone machine.
