But it is showing below error:
# fw_printenv
Cannot read the environment, using the default
Cannot read default environment from file
Below is the fw_env.config file
# cat /etc/fw_env.config
/dev/mmcblk2 0x400000 0x4000
I am doing partition using the parted command.
Below EMMC partition information.
