Flash area definition of HW config in FDL
The storage location and size of the hardware configuration file in the
internal flash memory must be defined as an “area” in the “Flash Layout
Table” of the Flash Device Label. Because the HW config is always stored
at the beginning of the flash device, we recommend you to define it as
“Area 0”.
Note:
The pre-configured FDL templates provided by Hilscher and the
FDLs that can be created in the
New Flash Device Label wizard of
netX Studio CDT already contain the required flash area definitions
of all files for the netX.
If you are using one of these FDLs, you thus do not need to enter
the flash area definition in the FDL yourself.
However, if you are not using a pre-configured FDL template or the
New Flash Device Label wizard of netX Studio CDT, but create
your own FDL with your own tool instead, you must define the flash
area for this file by entering the following values in the Flash Layout
Table of the FDL.

HIL_PRODUCT_DATA_FLASH_LAYOUT_CONTENT_TYPE_HWCONFIG
