Hi all,

I'm looking out for an elegant mechanism to perform an *application file upgradation remotely* in my Linux based Embedded System having JFFS2/FLASH as the storage filesystem. Note , I use u-boot in my system. I intend to do the following. My memory map would consist of the following 1) kernel image1(compressed) 2) kernel image2(compressed) 3) jffs2 application image1(compressed) 4) jffs2 application image2(compressed) 5) jffs2 data image1(un-compressed) [Will be written by the system applications]

Running on *1* & either *3* or *4* , I would update *2* , *3* or *4*, after which I indicate the completion in NVRAM flags. I'll rely on my bootloader to read the NVRAM flag to decide to load which kernel image & jffs2 application image.

Please comment on the above method. Rupesh
