fw_env.config file for Beaglebone Black


I am using Beaglebone Black, and booting from SD Card. The image was built using Yocto. I am trying to integrate swupdate for OTAs. swupdate expects fw_env.config file, which describes the u-boot settings. I am not able to find the right settings(i.e, right fw_env.config file) for my device. Is there any default fw_env.config file for Beaglebone Black? Could someone please help me with this?

Here is my fw_env.config file:
/dev/mmcblk0p1 0x0 0x1000 0x10000
