Hi Ashwin, You do not give many details here, so without even knowing which device we are talking about, it is hard to give you any advice.
To update Android, you basically have a few important components: 1. Linux kernel 2. Android's filesystem - home of all system code, apps, media, etc. How these things are stored in a device varies vastly from device to device. Some have it stored on a memory card as a plan linux kernel image file + ramdisk and then the Android filesystem in a real filesystem. Others store all these inside NAND flash in dedicated YAFFS2 partitions. You could even store these things on a harddrive if you like. The only thing in Android relating to update would be the fastboot protocol which is a way to transfer images from a host system (a PC) to the device for flashing which is supported by many Android devices. It is well documented online, but it does not seem like it is in play for your device. As I said - more information please :-) --- Henrik Uhrenfeldt Chief Software Engineer Ixonos Denmark ApS Niels Jernes Vej 10, DK-9220 Aalborg Ø, Denmark mobile +45 4030 2607 email: henrik.uhrenfe...@ixonos.com http://www.ixonos.com -----Original Message----- From: android-porting@googlegroups.com [mailto:android-port...@googlegroups.com] On Behalf Of Ashwin Bihari Sent: 27. maj 2010 19:33 To: android-porting Subject: [android-porting] Updating Android Guys, How are you, people with non-phone like embedded devices, running a particular version of Android supporting updating to a newer version? We have a device that doesn't have a keyboard and it looks like different phones out there use different key sequences to trigger a manual update. We would like to trigger this with an application which reads the update image from a USB flash drive. Does anyone have pointers as to where the Android upgrade/update code resides and how to interface to it?
