Hi
Is there a simple way to send data from a Linux user-space program to
U-Boot?
How about from U-Boot up to a user-space program?
The data may change often enough that using fw_printenv and fw_setenv might
wear out the NAND storage area for the environment.
The use-case is to have two kernel images, two root file systems, and to let
a user-space application specify which to use and then force a reboot. The
system will not lose power during this reboot.
This seems like a common enough problem. Has anyone solved it before?
