MSP430FR6972 使用两线SBW下载程序 The Debug Interface to the device has been secured

Other Parts Discussed in Thread: MSP430FR6972

如题

MCU是MSP430FR6972

调试器是MSP-FET430UIF

开发工具是CCS10.0.0

Console打印:MSP430: Error connecting to the target: The Debug Interface to the device has been secured

MCU的TCK和TDIO都有波形,没有成功下载过一次程序

望解惑!

  • 1 请问您是自己设计的板子?您之前是将什么固件加载到MSP430FR6972器件中?如果将0000_0000h或FFFF_FFFFh以外的任何其他值写入JTAG / SBW签名(地址FF80至FF83h),则这将锁定JTAG / SBW接口。在这种情况下,您将必须通过BSL重新对设备进行编程,以恢复通信。

    2 您是否已按照以下用户指南的图2-3所示配置Spy-bi-wire接口的原理图?取决于设备系列,并有2种不同的配置。
