SoloX field upgrade through Ethernet

ScottKerstein — Sat, 11 Jul 2015 02:38:42 GMT

Hello,

It's desired to get field upgrades via an Ethernet connection through a IOT website connection. Are there any app notes might exist to doing this on a SoloX, or just i.MX6 in general?

Need a way to ensure a failed upgrade does not compromise the machine and not enable it to take a subsequent upgrade
Would like a way to separate out the images so the GUI application can be upgraded separately from the rootfs and kernel
Would like to be able to sign and possibly encrypt the upgrade images.

Thanks, in advance.

Scott

It seems that you want to have something similar to what Google Play does, in Android which allows to upgrade the application without touching the system just the application, I would recommend to use Android as platform, and customize it, since it is prepared to such application
