Well, I guess we could get a little more creative with the image. I've kept to really simple... Right now the only difference between the dd/microSD image with the dd/flasher is one file in the boot partition.. /boot/uboot/flash-eMMC.txt https://github.com/beagleboard/image-builder/blob/master/scripts_device/boot/am335x_evm.sh#L56 Otherwise the biggest cpu hog was actually the screensaver. (xorg/lxde wasn't too resource intensive..) Which i've now disabled by default: https://github.com/beagleboard/image-builder/commit/6fe60d9a2f28d8f9f28747fd05f3cb0c96ef61ed So when i push out new image this week, it should shave a few more minutes.. (even without that change it's still not the 45 minutes it took Angstrom.. ;) ) > Another interesting note, is that once the rsync is done and the lights all > go solid, the GUI is still responsive and usable.

I wish we could "eject" the microSD, as if we halt, the user is just probably going to hit the power button and the flash starts all over..
