按照 https://www.cnblogs.com/debugdabiaoge/p/15975537.html 的方法，普通例程（如BLE_UART）可以成功改成OTA第二种方式。但是按照同样的方法修改adv_vendor_self_provision_with_peripheral例程时，却提示有些库函数找不到。
请问如何才能修改成功？
“OTA第二种方式”是不带库升级吗，操作的时候是合成了4个hex文件吗。默认例程就是不带库的方式，不用作修改，合成bin文件烧录即可。
现在还没到合成4个文件那一步，是编译都通不过，提示错误：

ld文件和.s文件有做相应修改吗，下面有篇博客可以参考。
CH573 CH582蓝牙sdk实现使用固定BLE LIB - debugdabiaoge - 博客园 (cnblogs.com)
EVT中支持mesh-OTA的芯片只有582以及208，573要移植的话可以参考582那边的默认例程。582的例程是默认带有BLE功能的，但是配网是需要走BLE直连节点的，移植到573上可能会有flash或者ram不够用的情况。
看了好像是libMESH.a库的问题，你看下错误提示，是libMESH.a里面的函数找不到调用的函数。

mesh_adapt.c:(.text.k_uptime_get_32+0x4): undefined reference to `TMOS_GetSystemClock'
问题可能是libMESH.a不支持CH57xBLE_ROM.h。当我去掉库LIBCH57xBLE.a，加上宏定义“CH57xBLE_ROM=1”后，libMESH.a就找不到函数了。
需求是想要用BLE进行OTA升级吗。
现在582的OTA升级是在mesh的基础上OTA升级的，是对mesh的库进行固定，提供了CH58XBLE_ROM_MESH文件，用wch mesh这个app进行升级，BLE库是和应用层一起编译的。
573不支持wch mesh的OTA，既要用mesh又要用ble，ram不够用的，所以没有提供CH57XBLE_ROM_MESH这个文件。
