We are developing an Android tablet, and are now looking at alternatives to providing a customer recovery/update feature similar to what's available for most Android phones on the market. Here are a few of our product details:
We have some very basic questions about how to provide this recovery feature:1) The TI distribution includes folder bootable/recovery, containing files such as recovery.c, bootloader.c, etc. The default build apparently compiles those files, and places the objects in folder target/product/am3517evm/obj/EXECUTABLES/recovery_intermediates. Do those files implement a reasonable approach for recovery?2) I've seen no documentation other than in the comments in those files. Does other documentation exist, and if so, where?3) How is recovery invoked? Apparently some phones do this with a special keypad sequence. What would we do on the am3517evm eval board?4) The recovery scheme apparently involves partitions 'cache' and 'recovery'. Is there a recommended means for creating those partitions, or is this strictly in our court as to how we create these partitions?Thanks,Ron
Recovery is not currently supported on TI Android DevKit. The sources that you refer to are directly from AOSP and are not customized for TI products.
However you may look at omapzoom or linaro android distributions for pointers to implement recovery/update.
It is possible, actually, it`s easy, you should untick the debug mode of the phone while you do the recovery, set the usb connection as mass storage, then software should recognize both the internal storage and sd card, download recover data for android, you can recover your deleted data without much fuss.
