GD32F130C6T6 可以直接刷入吗

[QGB]

原来的主板好像有读写保护，无法读取固件

 FMC提供了一个安全保护功能来阻止非法读取闪存。 此功能可以很好地保护软件和固件免受非法的用户操作。
  未保护状态：当将SPC字节和它的补字节被设置为0x5AA5，系统复位以后，闪存将处于非安全保护状态。主存储块和可选字节块可以被所有操作模式访问。
  已保护状态：当设置SPC字节和它的补字节值为任何除0x5AA5外的值，系统复位以后，安全保护状态生效。需要注意的是， 若该修改过程中，MCU的调试模块依然和外部JTAG/SWD设备相连，需要用上电复位代替系统复位以使得修改后的保护状态生效。在安全保护状态下，主存储闪存块仅能被用户代码访问且前4KB的闪存自动处于页擦除/编程保护状态下。 在调试模式下，或从SRAM中启动时，以及从boot loader区启动时，这些模式下对主存储块的操作都被禁止。如果在这些模式下读主存储块，将产生总线错误。如果在这些模式下，对主存储块进行编程或擦除操作， FMC_STAT寄存器的WPERR位将被置1。 但这些模式下都可以对可选字节块进行操作，从而可以通过该方式失能安全保护功能。如果将SPC字节和它的补字节设置为0x5AA5，安全保护功能将失效，并自动触发一次整片擦除操作。

GD32的读保护功能可以使用他们官方提供的ISP软件关闭，关闭后即可使用OpenOCD正常刷写固件。
