Enable this option by checking :ref:`CONFIG_SPIRAM_ALLOW_BSS_SEG_EXTERNAL_MEMORY`. This configuration setting is independent of the other three.
If enabled, a region of the address space starting from {IDF_TARGET_PSRAM_ADDR_START} will be used to store zero-initialized data (BSS segment) from the lwIP, net80211, libpp, and bluedroid ESP-IDF libraries.
If enabled, the region of the data virtual address space where the PSRAM is mapped to will be used to store zero-initialized data (BSS segment) from the lwIP, net80211, libpp, wpa_supplicant and bluedroid ESP-IDF libraries.
Additional data can be moved from the internal BSS segment to external RAM by applying the macro ``EXT_RAM_ATTR`` to any static declaration (which is not initialized to a non-zero value).

通过检查 :ref:`CONFIG_SPIRAM_ALLOW_BSS_SEG_EXTERNAL_MEMORY` 启用该选项，此选项配置与上面三个选项互不影响。
启用该选项后，从 {IDF_TARGET_PSRAM_ADDR_START} 起始的地址空间将用于存储来自 lwip、net80211、libpp 和 bluedroid ESP-IDF 库中零初始化的数据（BSS 段）。
启用该选项后，PSRAM 被映射到的数据虚拟地址空间将用于存储来自 lwip、net80211、libpp, wpa_supplicant 和 bluedroid ESP-IDF 库中零初始化的数据（BSS 段）。
``EXT_RAM_ATTR`` 宏应用于任何静态声明（未初始化为非零值）之后，可以将附加数据从内部 BSS 段移到片外 RAM。
