[SDK Release & Patch] ESP8266_RTOS_SDK_V1.3.3_16_07_04

Postby ESP_Faye » Fri Jun 24, 2016 10:37 pm



Release Notes
This patch is based on the ESP8266_RTOS_SDK_V1.3.0(68c9e7b4) and contains all changes updated within ESP8266_RTOS_SDK_V1.3.1(095c975c) and ESP8266_RTOS_SDK_V1.3.2(86e315aa). When this patch is used, .a files in this patch shall replace corresponding files under the SDK/lib Folder.
  1. Fix station leave issue in softap mode.(Resolved in ESP8266_RTOS_SDK_V1.3.1)
  2. 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_RTOS_SDK_V1.3.2)
  3. Fix a potential risk that will cause rf not work after external reset.(Resolved in ESP8266_RTOS_SDK_V1.3.3)
  4. Modify 112 byte of esp_init_data_default.bin, 0x03->0x00, turn off auto freq correction.(Resolved in ESP8266_RTOS_SDK_V1.3.3)
Attention: Please refer to “user_main.c” in the zip for “user_rf_cal_sector_set” sample code.

ESP8266_RTOS_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.

Have fun!

发布说明
本patch基于ESP8266_RTOS_SDK_V1.3.0(68c9e7b4),已包含1.3.1(095c975c), 1.3.2(86e315aa)的改动,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softap模式下,部分station离开可能导致的问题。(1.3.1中解决)
  2. 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”。 (1.3.2中解决)
  3. 修正外部复位后,小概率存在 rf 不工作的问题。(1.3.3中解决)
  4. 修改esp_init_data_default.bin的112字节,0x03->0x00,默认关闭频偏自动校正。(1.3.3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_RTOS_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。

感谢您对 ESP8266 的关注!
