* baremetal-helloworld: Fix IMGDEPLOYDIR expansionAlejandro Hernandez2020-04-291-0/+1
| | | | | | | | | | | | | | IMGDEPLOYDIR is not being expanded anymore, this causes do_rootfs to fail because it can't create the manifest file, we can set it to the default being set on image.bbclass since this is only a decoy function anyway to satisfy testimage, this makes do_rootfs happy and allows it to continue.

* baremetal-helloworld: Create recipe for baremetal examples on QEMUAlejandro Enedino Hernandez Samaniego2020-02-051-0/+105
Create HelloWorld examples that run on several of the QEMU architectures supported by the build system. This recipe can be used by anyone to understand how baremetal applications can be built using OpenEmbedded and how the wiring to set them up could be. This should also facilitate creating/extending the OE testing infrastructure to allow baremetal applications or RTOSs to be tested in the same way that Linux currently is. This can easily be extended to work on other MACHINES in the future. To run this example: $ source oe-init-buildenv $ bitbake-layers add-layer ../meta-skeleton # TCLIBC="baremetal" would work as well $ echo "TCLIBC = \"newlib\"" >> ./conf/local.conf $ echo "MACHINE = \"qemuarm64\"" >> ./conf/local.conf $ bitbake baremetal-helloworld $ runqemu runqemu - INFO - Running bitbake -e ... runqemu - INFO - Continuing with the following parameters: KERNEL: [tmp/deploy/images/qemuarm64/baremetal-helloworld-qemuarm64.bin] MACHINE: [qemuarm64] FSTYPE: [bin] ROOTFS: [tmp/deploy/images/qemuarm64/baremetal-helloworld-qemuarm64.bin] CONFFILE: [tmp/deploy/images/qemuarm64/baremetal-helloworld-qemuarm64.qemuboot.conf] Hello OpenEmbedded!
