前提：
SDK：ESP8266_RTOS_SDK-2.0.0
基于：websocket_demo 进行开发。

现象：
main_init中：加入 wifi_set_event_handler_cb(wifi_handle_event_cb);
编译不通过
错误信息如下：

如果将wifi_set_event_handler_cb(wifi_handle_event_cb);这句话去掉，编译可以通过。

问题：
是不是默认引入的库不够啊？ 有知道的朋友，请指点。

这个问题可以断定是:
3.14. 为什什么编译的时候会发⽣生“irom0_0_seg”错误？

它表示代码量量太⼤大，IROM 区域存放不不下了了。
我们可以在 SDK_v0.9.5（及之后）的软件版本中，尝试如下步骤，解决这个问题:
1. 使⽤用默认设置，编译⽣生成 eagle.flash.bin 和 eagle.irom0text.bin。
(1) 如果 size of eagle.flash.bin + size of eagle.irom0text.bin >=
236KBytes：很抱歉，您的代码量量太⼤大了了，只能换⼤大些的 Flash。
(2) 如果 size of eagle.flash.bin + size of eagle.irom0text.bin <
236KBytes：
请继续步骤 2。
2. 在路路径 SDK/ld 下修改⽂文件“eagle.app.v6.new.512.app1.ld”。
irom0_0_seg : org = 0x40201010, len = 0x2B000
根据步骤 1 中编译的“eagle.irom0text.bin”⼤大⼩小，改写上述 len 的值。
示例例：如果“eagle.irom0text.bin”⼤大⼩小为 179 KB，则可修改配置如下：
irom0_0_seg : org = 0x40201010, len = 0x2D000
3. 重新编译 user1.bin 选择 boot_v1.2+。
补充说明：
代码中，
• 函数前未加 ICACHE_FLASH_ATTR 的，编译到 IRAM 中，最⼤大 32 KB；
• 函数前加了了 ICACHE_FLASH_ATTR 的，编译到 IROM 中；
因为 RAM的空间有限，因此做了了这两个部分的区分：
• IRAM 中的代码，会在上电初始就完整加载到 RAM 中；
• IROM 中的代码是⽤用到的时候才从Flash 加载到 cache 中执⾏行行。

然而文档里这段话，没啥用啊？ 修改长度后：
MEMORY
{
dport0_0_seg : org = 0x3FF00000, len = 0x10
dram0_0_seg : org = 0x3FFE8000, len = 0x18000
iram1_0_seg : org = 0x40100000, len = 0x8000
irom0_0_seg : org = 0x40220000, len = 0x6C000
}
编译通过了,编译参数：
generate bin: eagle.flash.bin+eagle.irom0text.bin
spi speed: 40 MHz
spi mode: QIO
STEP 5: choose spi size and map
3=2048KB( 512KB+ 512KB)

烧写参数：
eagle.flash.bin 0x0
eagle.irom0text.bin 0x20000
esp_init_data_default.bin 0x1fb000
只选了这三项。

问题是运行不了啊？？？

这个问题搞定了，多看文档就好了。 2a-esp8266-sdk_getting_started_guide_cn.pdf
