Append the necessary QB_ flags to the MACHINE configuration of beaglebone-yocto. Using Qemu with "-machine virt" simplifies things greatly because for this machine the dtb is compiled into qemu. Since the beaglebone-yocto kernel config also supports this cpu architecture, it just works. However, u-boot is not involved and the virt machine is not 100% equal to a am335x SoC. A MACHINE configuration suitable for Qemu as well as for the real hardware allows to provide just one eSDK where both runqemu and devtool build-image work. Otherwise a qemuarm and a beaglebord-yocto MACHINE eSDK would be required to support development in Qemu as well as on real hardware.

QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
