Release Notes
This patch is based on the ESP8266_NONOS_SDK_V1.5.2. When this patch is used, .a files in this patch shall replace corresponding files under the SDK/lib Folder.
  1. Resolved an issue that RF_Init_data sector may be broken in stress test. Provided a function “user_rf_cal_sector_set” which has to be added in application by software developer. More details about user_rf_cal_sector_set refer to documentation “2C-ESP8266__SDK__API Guide”.(Resolved in ESP8266_NONOS_SDK_V1.5.2.1)
  2. Isolated cases of rf failure after external reset have been debugged.(Resolved in ESP8266_NONOS_SDK_V1.5.2.1)
  3. Modify 112 byte of esp_init_data_default.bin, 0x03->0x00, turn off auto freq correction. (Resolved in ESP8266_NONOS_SDK_V1.5.2.1)
Attention: Please refer to “user_main.c” in the folder for “user_rf_cal_sector_set” sample code.

ESP8266_NONOS_SDK Note:
  1. esp_init_data.bin has to be downloaded into flash at least once.
  2. Download blank.bin to initialize the sector stored RF_CAL parameter (set by user_rf_cal_sector_set), and download esp_init_data.bin into flash, when the system needs to be initialized, or RF needs to be calibrated again.

AT Note:
  1. Since the release of ESP8266_NONOS_SDK_V1.5.0, AT firmware is too large to use 4Mbit flash. Please choose flash with at least 8Mbit capacity.
  2. Firmware upgrade over-the-air process is changed a bit. We will upgrade the latest AT firmware to Espressif Cloud server only after it has been tested and the overall performance is guaranteed. Users may not be able to use AT+CIUPDATE in ESP8266_NONOS_SDK_V1.5.0 and other more advanced versions.


Have fun!

发布说明
本patch基于ESP8266_NONOS_SDK_V1.5.2，使用时将压缩包中.a文件覆盖SDK/lib目录下对应文件。
  1. 修正部分情况下，RF_Init_data 系统参数区可能被破坏的问题。新增 user_rf_cal_sector_set，用户程序必须实现此接口，详细参见文档 “2C-ESP8266__SDK__API Guide”。 (1.5.2.1中解决）
  2. 修正外部复位后，小概率存在 rf 不工作的问题。（1.5.2.1中解决）
  3. 修改esp_init_data_default.bin的112字节，0x03->0x00，默认关闭频偏自动校正。（1.5.2.1中解决）
注意：基于更新1的示例代码可参考压缩包中的user_main.c。

ESP8266_NONOS_SDK 注意事项:
  1. esp_init_data.bin 至少需要烧录一次到 flash。
  2. 建议整个系统需要做初始化设置时，或需要重新进行 RF_CAL 时，烧录 blank.bin 到 RF_CAL 参数区 (由 user_rf_cal_sector_set 设置)，并烧录 esp_init_data.bin 到 flash。

AT 注意事项:
  1. 从版本 ESP8266_NONOS_SDK_V1.5.0 起，AT 固件所需空间增大，无法再使用 4Mbit (512KB) Flash，请使用 8Mbit (1MB) 或以上容量 Flash。
  2. 我司优化了 AT 固件的升级流程，AT 固件发布后，会等一段时间，待客户反馈稳定后，才上传到 Espressif Cloud 以供下载更新。因此，如果使用 ESP8266_NONOS_SDK_V1.5.0 及之后版本的 AT 固件暂时无法从 Espressif Cloud 升级。
