Hi Brian,

Hi all, What is the recommended way to update u-boot parameter (such as network IP) from linux? In the past, I just updated the parameter sector in the flash by calculating the check sum and wrote the new data to the flash directly from linux application. This works ok if u-boot is not updated. I realized that u-boot has changed the way it writes the parameter to the flash since we used in on our last hardware (version 1.0.0) and am wondering if there is a better way to do this.
Use the fw_printenv/fw_setenv application in the tools/env directory. It's a user-space app that can access your environment if you make it visible through MTD.
