Hi All,
Is it Possible from Linux to set an environment variable of u-Boot.?
This is for Firmware up gradation.
Currently Linux has 4 mtd partitions in flash
mtd0 : U-Boot mtd1: JFFS file system (Golden image) mtd2: JFFS file system (Silver image) mtd3: Configs
U boot does an fsload of uImage(Linux image) from Golden JFFS and boots up Linux.
Now from Linux I can download a new JFFS(Silver) and flash it to mtd2 partition of Flash.
Is there any mechanism that Linux acknowledges the u-boot about the new jffs image that next time it has to do an fsload of uImage(Linux image) from Silver JFFS , not Golden JFFS.
I thought of Doing this using some environment variables .
But after a successful download of new jffs and writing to mtd2 partition , How will Linux update the environment variable of U-boot?
Any better idea for firmware up gradation?
Expecting your Suggestions and Help
Thanks Rahanesh
