- You can now run 'bitbake <target>'
- Common targets are:
- EOF
- finddir=`ls -d $OEROOT/../meta-*/ | grep -v $OEROOT/../meta-openembedded | grep -v $OEROOT/../meta-riscv`
- targets=`find $finddir -wholename '*/images/*.bb'`

- cat <<EOF
- You can also run generated qemu images with a command like 'runqemu qemux86'.
- Other commonly useful commands are:
- - 'devtool' and 'recipetool' handle common recipe tasks
- - 'bitbake-layers' handles common layer tasks
- - 'oe-pkgdata-util' handles common target package tasks
- EOF
