[U-Boot] fw_(printenv/setenv) and serial console have different env variables
Greetings everyone,
I stumbled over something worth telling.
It started as the bad crc using defaults issue when I tried to use fw_printenv on my debian iconnect box. I tought it was the fw_env.config. it wasn't. After hours of researching and compiling from source and the whole lot of trouble shooting I took the chance to use fw_setenv.
Bingo! it worked. Now fw_printenv gives me no bad crc and prints the variables including the new ones even after reboot.
NOW HERE IS THE ISSUE
The env variables printed from linux don't show on the serial and viceversa. It looks like there are 2 sets of them. Needless to say that it's frustrating.
Anyone has seen anything similar?

How do I merge this two? Thanks and regards.

My thoughts are that your u-boot is storing the env in a different area than what your fw_env.config is pointing to in debian. Hence the crc error. Of course you can get rid of the crc error by running fw_setenv, as it just dumps the default env in the space defined in the config file.

Here I see that Device offset is 0xa0000 (which fw_printenv works with), and looking at include/configs/iconnect.h CONFIG_ENV_OFFSET is 0x80000. The sizes do match. Hence, can you try to change fw_env.config to have a device offset of 0x80000 and see if you get same envs?
