[U-Boot-Users] bad CRC, using default environment
Hello
I have just installed u-boot 1.1.1 on a Phoenix-SBC single board computer from Axotec. When u-boot starts up the following warning appears:
*** Warning - bad CRC, using default environment
I can set new environment variables with "setenv". When I want to save the new variables with the command "saveenv" the following messages appears in the shell:
Saving Environment to Flash... Un-Protected 1 sectors Erasing Flash...Erasing sector 1 ... ok. Erased 1 sectors Writing to Flash... Flash not Erased <-- Is there something wrong? Protected 1 sectors
When I restart the system there is still the bad CRC warning and all changes in the environment variables are lost. Has anybody an idea why I can not save the environment variables?
Regards Niklaus Burren

Yes, there is something wrong. Your U-Boot configuration is brokn; either the flash driver failed to erase the flash, or it does not match the sector layout of the used chips.

Because the image you installed is misconfigured and/or broken.
