 ## Overview
 The `bootloader support plus` is an enhanced bootloader based on [custom_bootloader](https://github.com/espressif/esp-idf/tree/master/examples/custom_bootloader) . The firmware update function is supported in the bootloader stage by decompressing the compressed firmware. In this solution, you can directly use the original OTA APIs (such as [esp_ota](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/system/ota.html#api-reference)、[esp_https_ota](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/system/esp_https_ota.html#api-reference)). The following table shows the Espressif SoCs that are compatible with `bootloader support plus` and their corresponding ESP-IDF versions.

 ## 概述
 bootloader support plus 是乐鑫基于 [ESP-IDF](https://github.com/espressif/esp-idf) 的 [custom_bootloader](https://github.com/espressif/esp-idf/tree/master/examples/custom_bootloader)  推出的增强版 bootloader，支持在 bootloader 阶段对`压缩`的固件进行 `解压缩`，来升级原有固件。在该方案中，您可以直接使用 ESP-IDF 中原生的 OTA 接口（比如 [esp_ota](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/system/ota.html#api-reference)、[esp_https_ota](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/system/esp_https_ota.html#api-reference)）。下表总结了适配 `bootloader support plus` 的乐鑫芯片以及其对应的 ESP-IDF 版本：
