            The partition table to flash to the ESP32. The partition table
            determines where apps, data and other resources are expected to
            be found.

            The predefined partition table CSV descriptions can be found
            in the components/partition_table directory. Otherwise it's
            possible to create a new custom partition CSV for your application.

            Name of the custom partition CSV filename. This path is evaluated
            relative to the project root directory.

        default 0x8000
        help
            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.

            This number should 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.

        help
            Generate an MD5 checksum for the partition table for protecting the
            integrity of the table. The generation should be turned off for legacy
            bootloaders which cannot recognize the MD5 checksum in the partition
            table.
