Copies a list of image partitions into an image buffer and generates the image partition table while doing so

|
|
Example image partition table:
|
|
|
|
fwup-ptn partition-table base 0x00800 size 0x00800
|
|
fwup-ptn os-image base 0x01000 size 0x113b45
|
|
fwup-ptn file-system base 0x114b45 size 0x1d0004
|
|
fwup-ptn support-list base 0x2e4b49 size 0x000d1
|
|
|
|
Each line of the partition table is terminated with the bytes 09 0d 0a ("\t\r\n"),
|
|
the end of the partition table is marked with a zero byte.
|
|
|
|
The firmware image must contain at least the partition-table and support-list partitions
|
|
to be accepted. There aren't any alignment constraints for the image partitions.
|
|
|
|
The partition-table partition contains the actual flash layout; partitions
|
|
from the image partition table are mapped to the corresponding flash partitions during
|
|
the firmware upgrade. The support-list partition contains a list of devices supported by
|
|
the firmware image.
|
|
|
|
The base offsets in the firmware partition table are relative to the end
|
|
of the vendor information block, so the partition-table partition will
|
|
actually start at offset 0x1814 of the image.
|
|
|
|
I think partition-table must be the first partition in the firmware image.
