ESP82661M FLASH OTA 错误解决

一、环境

1. SDK版本：RTOS3.0
2. 板子为1M的FLASH

二、问题

调用 esp_ota_end 出现下面错误

三、解决方法

1. 此方法不建议：打开 CONFIG_ESP8266_BOOT_COPY_APP

2. 建议方法：SDK找到对应的issue：https://github.com/espressif/ESP8266_RTOS_SDK/issues/745
   修改方法为：ESP8266_RTOS_SDK\components\app_update\esp_ota_ops.c文件中

   Changing the code (see my first post) from:
   if (pos->offset + pos->size <= 0x100000) {
   
   To:
   if (pos->offset + pos->size < 0x100000) {
   

3. 分区别再增加一点，原本大小只是 0x70000

   # Name,   Type, SubType, Offset,   Size, Flags
   # Note: if you change the phy_init or app partition offset, make sure to change the offset in Kconfig.projbuild
