<p dir="auto">我直接从flashdrv的那个工程(bin_project),把这几个函数挪到我的APP代码里，可以吗？<br />

<p dir="auto">我原来1.3.1的flashdrv已经出过货了，我不想更改flashdrv了，但是又因为信息安全，我在app中不能开启flash模块。我可以直接把flashdrv工程里面的FLASH_DRV_ReadNVR、FLASH_DRV_ProgramNVR、FLASH_DRV_EraseNVR拷贝到APP里面来实现吗？我在FLASH_LaunchCommandSequence里面限定用于擦写CUS_NVR</p>

YTM32B1ME0和 YTM32B1MD1 需要使用这两个API进行CUS NVR操作，操作前去要unlock cus key。</p>
<pre><code>/* Unlock cus nvr area */
/* (*((volatile uint32_t *)0x40010204)) = 0x4dff32 */ 
EFM-&gt;CUS_KEY = 0x4dff32;

<p dir="auto">我能不能不替换flashdrv，用<br />
status_t FLASH_DRV_EraseSector(uint32_t dest, uint32_t size);<br />
status_t FLASH_DRV_Program(uint32_t dest, uint32_t size, const void *pData);<br />
能实现擦写NVR吗</p>
