ESP32 When compiling, configure the Partition Table through Make Menuconfig to support the Single Factory App, No OTA, Factory App, Two OTA Definitions, CUSTM PARTITION TABLE CSV

Note 1: Lexin may change these burning positions in different versions of SDK. The following description is only for reference. It is recommended that the console output information during development shall prevail.
