This has worked just fine, but, it turns out, only because I've never had CONFIG_PARTITION_TYPE_GUID enabled on any of my boards; I've always just set the offsets of the two partitions via the config variables CONFIG_ENV_OFFSET(,_REDUND). I didn't even know that env/mmc.c had learnt to look for the env partition based on the type GUID, or that that would overrule the ENV_OFFSET config variables, until I experienced weird random corruption while doing bringup for an stm32 board, where PARTITION_TYPE_GUID is automatically set because it is select'ed by CMD_STM32PROG. These patches try to fix the code to fit my scheme, while not changing anything for existing setups that use the two-copies-one-partition scheme, other than complaining loudly if the system is misconfigured and avoiding such random corruption of neighbouring partitions. --- 667a671ccab9e6cfe04c654e2c935ea0a070f58b
