<DIV style="FONT-SIZE: 12pt; FONT-FAMILY: times new roman, new york, times, serif"> </DIV>
<DIV style="FONT-SIZE: 12pt; FONT-FAMILY: times new roman, new york, times, serif">I have a linux 2.6 kernel running on ARM9 based target. i have a U-Boot as boot loader.</DIV>
<DIV style="FONT-SIZE: 12pt; FONT-FAMILY: times new roman, new york, times, serif">I need to do a software upgrade.I am explaining my approach :-</DIV>
<DIV style="FONT-SIZE: 12pt; FONT-FAMILY: times new roman, new york, times, serif"> </DIV>
<DIV style="FONT-SIZE: 12pt; FONT-FAMILY: times new roman, new york, times, serif">My system is having a well defined GUI with touch screen on it.So when running linux application with GUI and touchscreen</DIV>
<DIV style="FONT-SIZE: 12pt; FONT-FAMILY: times new roman, new york, times, serif">user can send a command that he wants to upgrade the software ( include kernel + root file system + application) via touchscreen GUI.</DIV>
<DIV style="FONT-SIZE: 12pt; FONT-FAMILY: times new roman, new york, times, serif">As far as my understanding goes i think application need to write something on flash( let us say change flag=1) so that next time when system reboots it U-boot read the variable status from same flash location so that it should not boot from flash and use tftfp downlaod and when download gets completed it changes the status of variable in order to make u-boot loading image from flash for next time onwards.</DIV>
<DIV style="FONT-SIZE: 12pt; FONT-FAMILY: times new roman, new york, times, serif"><BR><BR>Is it possible to do the software upgrade like the way i have explained , if not pls suggest a better way of doing it using U-boot.But my only requirement is, i dont want to go to U-boot command prompt and do the upgrades manually. I need some kind of automatic approach which basically start when my application is running.</DIV>
<DIV style="FONT-SIZE: 12pt; FONT-FAMILY: times new roman, new york, times, serif"> </DIV>
<DIV style="FONT-SIZE: 12pt; FONT-FAMILY: times new roman, new york, times, serif">Thanks</DIV>
