In the CFG_ENV_ADDR_REDUND version of the function saveenv in common/env_flash.c...
If there is a failure with the flash_write function it will always display an error message for a Flash Timeout regardless of what the actual error is. The variable "rc" is set to 1 at declaration and flash_perror(rc) is called if there is an error, but the actual return value of flash_write is not stored in rc, therefore the error code displayed will always be 1.
The below patch corrects this...
