It sounds very nice and useful - but what is it and why is this so exciting :) ?

" Basically a gadget that allows you to use one sd card shared by two computers.
Power off computer A and computer B will see the sdcard. Power on computer A and sd card will get unplugged from computer B; computer A can use it exclusively until it gets powered off again.

In short: good stuff ... "

Thanks for the explanation - it would be nice if such a comment were in the original post on linaro-dev rather than a one line comment with no explanation anywhere for mere mortals :)
" Basically a gadget that allows you to use one sd card shared by two computers.
Power off computer A and computer B will see the sdcard. Power on computer A and sd card will get unplugged from computer B; computer A can use it exclusively until it gets powered off again.
(Assuming that computer B is powered off at the same time that Computer A comes on) Interesting though I'm not sure where I'd use it and how it would work if I had a running computer B and it was using that device :)

It might well be, but it's hard to understand with cryptic juxtaposition of terms :-/ "Dual SD Card" really doesn't convey that meaning !!

It's essentially being developed for LAVA so that we can test a complete image, including u-boot (or uefi or whatever) as well as the boot and rootfs alone.

No, computer B can remain powered on all the time. Imagine computer A being a Pandaboard with power controlled by computer B, a PC. Now the PC can power off the Pandaboard, write an image to the card, and power on the Panda again. This allows fully automatic recovery from a bad boot loader/kernel.

Ah thanks - that makes a lot more sense now.
