The address of partition table (by default 0x8000).
Allows you to move the partition table, it gives more space for the bootloader.
Note that the bootloader and app will both need to be compiled with the same PARTITION_TABLE_OFFSET value.
The offset address of the partition table is, by default, 0x8000, and it starts right after
the bootloader. This offset can be changed if more space is required for the bootloader.
If you change this offset, both the bootloader and the app must be compiled with the same
PARTITION_TABLE_OFFSET value.
This number should be a multiple of 0x1000.
This value must be a multiple of 0x1000.
Note that partition offsets in the partition table CSV file may need to be changed if this value is set to
a higher value. To have each partition offset adapt to the configured partition table offset, leave all
partition offsets blank in the CSV file.
If you change the partition table offset, make sure to update the partition offsets in
the partition table CSV file. To let the build system automatically adjust partition offsets based on
the configured partition table offset, leave the offset fields blank in the CSV file.
Note: If you specify fixed offsets in the partition table CSV (i.e., the offset column is not blank),
the first partition must start at PARTITION_TABLE_OFFSET + 0x1000, since the partition table occupies
0x1000 bytes of flash space.
