Will we build some for LAVA folks to play with? It sounds very nice and useful - but what is it and why is this so exciting :) ? I gave a bit background as a comment to my post: - https://plus.google.com/u/0/117775935412882278033/posts/8JTBhQSkUdS 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. ...

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. -- Mans Rullgard / mru ___ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
