913 fwup-ptn os-image base 0x01000 size 0x113b45

915 fwup-ptn support-list base 0x2e4b49 size 0x000d1
916
917 Each line of the partition table is terminated with the bytes 09 0d 0a ("\t\r\n"),
918 the end of the partition table is marked with a zero byte.
919
920 The firmware image must contain at least the partition-table and support-list partitions
921 to be accepted. There aren't any alignment constraints for the image partitions.
922
923 The partition-table partition contains the actual flash layout; partitions
924 from the image partition table are mapped to the corresponding flash partitions during
925 the firmware upgrade. The support-list partition contains a list of devices supported by
926 the firmware image.
927
928 The base offsets in the firmware partition table are relative to the end
929 of the vendor information block, so the partition-table partition will
930 actually start at offset 0x1814 of the image.
931
932 I think partition-table must be the first partition in the firmware image.
