Each ocd data corresponds to an index value. You can use index to get ocd data. The OCD indicator value
enumeration is shown below.
enum ocd_lockable_table
{
magic_number = 0, //ocd.index.0
magic_number_factory = 1, //ocd.index.1
revision = 2, //ocd.index.2 and so on...
system_ocd = 3,
modem = 4,
gps = 5,
module_sn = 6,
board_sn = 8,
product_sn = 10,
wifi_mac_ap = 12,
wifi_mac_sta = 13,
wifi_mac_p2p = 14,
wifi_cy_code = 15,
bt_mac = 16,
barcode = 17,
wifi_mac_go = 18,
ocd_last_stc, //Hold this in the last item
};
