Changing U-boot environment variable

Chip Platform Rockchip
1

Hello All,
I have added extra environment variable in rockchip u-boot. I can modify and save its value at uboot prompt through setenv and sa option. Further, I want to change u-boot env varaible once I entered into rootfs. I guess there is u-boot utility fw_setenv by which we can set u-boot env. Does any one has compiled this fw_setenv tool for rk3288.

Thanks
