Chapter 2. API Reference
CONFIG_ESP_PHY_INIT_DATA_IN_PARTITION
Use a partition to store PHY init data
Found in: Component config > PHY
If enabled, PHY init data will be loaded from a partition. When using a custom partition table, make
sure that PHY data partition is included (type:‘data’, subtype:‘phy’). With default partition tables,
this is done automatically. If PHY init data is stored in a partition, it has to be flashed there, otherwise
runtime error will occur.
If this option is not enabled, PHY init data will be embedded into the application binary.
If unsure, choose ‘n’.
Default value:
• No (disabled)
Contains:
• CONFIG_ESP_PHY_DEFAULT_INIT_IF_INVALID
• CONFIG_ESP_PHY_MULTIPLE_INIT_DATA_BIN
CONFIG_ESP_PHY_DEFAULT_INIT_IF_INVALID
Reset default PHY init data if invalid
Found in: Component config > PHY > CONFIG_ESP_PHY_INIT_DATA_IN_PARTITION
If enabled, PHY init data will be restored to default if it cannot be verified successfully to avoid endless
bootloops.
If unsure, choose ‘n’.
Default value:
• No (disabled) if CONFIG_ESP_PHY_INIT_DATA_IN_PARTITION
CONFIG_ESP_PHY_MULTIPLE_INIT_DATA_BIN
Support multiple PHY init data bin
Found in: Component config > PHY > CONFIG_ESP_PHY_INIT_DATA_IN_PARTITION
If enabled, the corresponding PHY init data type can be automatically switched according to the country
code. China’s PHY init data bin is used by default. Can be modified by country information in API
esp_wifi_set_country(). The priority of switching the PHY init data type is: 1. Country configured by
API esp_wifi_set_country() and the parameter policy is WIFI_COUNTRY_POLICY_MANUAL. 2.
Country notified by the connected AP. 3. Country configured by API esp_wifi_set_country() and the
parameter policy is WIFI_COUNTRY_POLICY_AUTO.
Default value:
• No (disabled) if CONFIG_ESP_PHY_INIT_DATA_IN_PARTITION && CON-
FIG_ESP_PHY_INIT_DATA_IN_PARTITION
CONFIG_ESP_PHY_MULTIPLE_INIT_DATA_BIN_EMBED
Support embedded multiple phy init data bin to app bin
Found in: Component config > PHY > CONFIG_ESP_PHY_INIT_DATA_IN_PARTITION > CON-
FIG_ESP_PHY_MULTIPLE_INIT_DATA_BIN
If enabled, multiple phy init data bin will embedded into app bin If not enabled, multiple phy init data
bin will still leave alone, and need to be flashed by users.
Default value:
• No (disabled) if CONFIG_ESP_PHY_MULTIPLE_INIT_DATA_BIN && CON-
