[yocto] yocto beaglebone build no uImage on DOS partition.

[Rudolf Streif]

Edward,

Yes, you do need of course a uImage which is the Linux kernel image with
the necessary wrapper for u-boot. If you do not have one after your build
finishes in <path-to-build-env>/tmp/deploy/images then building the Linux
kernel failed and you should look for error messages.

To build just the kernel you can run

MACHINE=beaglebone bitbake virtual/kernel -vDD

It seems that inside your build environment you are mixing builds for
BeagleBone and PandaBoard. You need to pay attention to that since the
BeagleBone uses a TI Sitara AM335x SoC and the PandaBoard a TI OMAP4430
SoC. They are both ARM but substantially different.
