Espressif ESP32-S2 User Manual

Chapter 2. API Reference
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 direc-
tory. These are mostly intended for example and development use, it’s expect that for production use
you will copy one of these CSV files and create a custom partition CSV for your application.
Available options:
• Single factory app, no OTA (PARTITION_TABLE_SINGLE_APP)
This is the default partition table, designed to fit into a 2MB or larger flash with a single 1MB
app partition.
The corresponding CSV file in the IDF directory is compo-
nents/partition_table/partitions_singleapp.csv
This partition table is not suitable for an app that needs OTA (over the air update) capability.
• Single factory app (large), no OTA (PARTITION_TABLE_SINGLE_APP_LARGE)
This is a variation of the default partition table, that expands the 1MB app partition size to
1.5MB to fit more code.
The corresponding CSV file in the IDF directory is compo-
nents/partition_table/partitions_singleapp_large.csv
This partition table is not suitable for an app that needs OTA (over the air update) capability.
• Factory app, two OTA definitions (PARTITION_TABLE_TWO_OTA)
This is a basic OTA-enabled partition table with a factory app partition plus two OTA app
partitions. All are 1MB, so this partition table requires 4MB or larger flash size.
The corresponding CSV file in the IDF directory is compo-
nents/partition_table/partitions_two_ota.csv
• Custom partition table CSV (PARTITION_TABLE_CUSTOM)
Specify the path to the partition table CSV to use for your project.
Consult the Partition Table section in the ESP-IDF Programmers Guide for more information.
• Single factory app, no OTA, encrypted NVS (PARTI-
TION_TABLE_SINGLE_APP_ENCRYPTED_NVS)
This is a variation of the default “Single factory app, no OTA”partition table that supports
encrypted NVS when using flash encryption. See the Flash Encryption section in the ESP-IDF
Programmers Guide for more information.
The corresponding CSV file in the IDF directory is compo-
nents/partition_table/partitions_singleapp_encr_nvs.csv
• Single factory app (large), no OTA, encrypted NVS (PARTI-
TION_TABLE_SINGLE_APP_LARGE_ENC_NVS)
This is a variation of the “Single factory app (large), no OTA”partition table that supports
encrypted NVS when using flash encryption. See the Flash Encryption section in the ESP-IDF
Programmers Guide for more information.
The corresponding CSV file in the IDF directory is compo-
nents/partition_table/partitions_singleapp_large_encr_nvs.csv
• Factory app, two OTA definitions, encrypted NVS (PARTI-
TION_TABLE_TWO_OTA_ENCRYPTED_NVS)
This is a variation of the “Factory app, two OTA definitions”partition table that supports
encrypted NVS when using flash encryption. See the Flash Encryption section in the ESP-IDF
Programmers Guide for more information.
The corresponding CSV file in the IDF directory is compo-
nents/partition_table/partitions_two_ota_encr_nvs.csv
