我使用SDK_6.0.14.1114.zip，并打上了补丁SDK_6.0.14.1114_hotfix_001.zip

打补丁的方法是，In the extracted SDK folder, replace the the following folders with the one provided in the hotfix release:
* binaries
* doc
* config/toolbox_resources
* sdk/platform/system_library

我在keil中编译projects\target_apps\ble_examples中的prox_reporter和ble_app_barebone工程都会报同样的错误，错误如下

".\out_DA14531\Objects\prox_reporter_531.axf" - 3 Error(s), 0 Warning(s).

我在工程中没有搜索到llm_dflt_bdaddr、llm_wlpriv_addr_set、llm_wlpub_addr_set这几个符号。

请问如何解决这个问题？
