# The detection has to be done via the hardcoded mtd partition because

# the current boot might be done with the fallback region. Let us

# assume that the current bootseq is 1,2. The bootloader detected that

# the image in flash region 1 is corrupt and thus switches to flash
|

# region 2. The bootseq in the u-boot-env is now still the same and

# the sysupgrade code can now only rely on the actual mtd indexes and

||||
# not the bootseq variable to detect the currently booted flash
|
||||
# region/image.
|

#
|
||||
# In the above example, an implementation which uses bootseq ("1,2") to
|
||||
# detect the currently booted image would assume that region 1 is booted
|
||||
# and then overwrite the variables for the wrong flash region (aka the
|
||||
# one which isn't modified). This could result in a device which doesn't
|

# boot anymore to Linux until it was reflashed with ap51-flash.
