Partition_Modification

The partition.mbn file is the partition table flashed to the module, located in the \update directory of the firmware package. To generate this file, use the partition_nand.xml configuration file found in the same directory. When adjusting partition(s), replace the XML file with the identical name in the SDK with the one in the firmware package before making any modifications. The content of the configuration file is shown below
