I want to implement fail-safe booting feature in my project. Basically my logic is, i will increase any u-boot environment variable each time and up on successful bring up, i want to decrease the value of that again. If the value of u-boot environment variable is more than 5, it will boot from the other image. As i am using the eMMC for booting, i am not getting how i will access the u-boot environment variable from the linux application. I also dont know whether i can save the environment variable in the eMMC or not? What mechanism i should use to achieve this feature. I have read about the fw_printenv and fw_savenv, but from where this utility will access the variable.
