# The U-Boot loader of the OpenMesh devices requires image sizes and

# The OpenMesh devices come with 2 main partitions - while one is active

# sysupgrade will flash the other. The boot order is changed to boot the
|

# newly flashed partition. If the new partition can't be booted due to

# detect to which flash region the new image is written to.
|

#
|

# 1. check what is the mtd index for the first flash region on this
|
||||
# device
|
||||
# 2. check if the target partition ("inactive") has the mtd index of
|
||||
# the first flash region
|
||||
#
|
||||
# - when it is: the new bootseq will be 1,2 and the first region is
|
||||
# modified
|
||||
# - when it isnt: bootseq will be 2,1 and the second region is
|
||||
# modified
|
||||
#
|
||||
# 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.
