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.
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.
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?

Here I see that Device offset is 0xa (which fw_printenv works
with), and looking at include/configs/iconnect.h CONFIG_ENV_OFFSET is
0x8. The sizes do match.
Hence, can you try to change fw_env.config to have a device offset of
0x8 and see if you get same envs?

How do I merge this two?
Thanks and regards.
