Dear Rahanesh,

Is it Possible from Linux to set an environment variable of u-Boot.?
If your environment is stored in NOR or NAND flash, then you can use the tools from the tools/env/ directory (fw_setenv / fw_printenv).
It should be trivial to adapt the code for other storage devices, too.
But after a successful download of new jffs and writing to mtd2 partition , How will Linux update the environment variable of U-boot?
Use fw_setenv.
Best regards,
