Thanks for the information. I just wanted to have a
feedback, whether
having a use-case of writing env variables from Linux
User space is a
good idea or is not recommended?
You found tools/env/fw_env.c showing that this functionality is indeed foreseen and used.
It is rather common to write to the U-Boot environment in projects for example to switch to a new set of kernel+file system after an update from within linux for the next boot.
My use case is exactly same, to switch to a new set of kernel+fs after an update for the next boot.
I also have another usecase of updating the env variable 'bootargs' if required in the field. So this use-case combined with fw_env, what is your feedback?
Could you give me some pointers on upgrading u-boot itself, but I don't have a spare partition for that. I would have to replace working copy itself?
I would wanted to have more info(in addition to what I have implemented) regarding the failsafe upgrade mechanisms for embedded-linux apps and kernel? Could you please point me to right forums regarding this. I understand that this is not specific to u-boot, but just give me some pointers.
regards -Nitin
Is this feedback enough?
Cheers Detlev
