MSPM0L1305: KEIL5 IDE可以下载但不能调试运行

hi all,

我使用KEIL5 IDE 创建开发环境， 在MSP0L1306的demo板子上可以下载并调试成功。但是我们自己的板子使用的MCU是MSPM0L305，24PIN。使用keil5可以成功下载程序，但是无法调试运行。log如下：

我们在这个链接中讨论。

1、我们用的MCU型号是MSPM0L1305TRGER。PA18引脚我们想复用为AD检测电源电压，现在的问题是PA18有BSL_invoke功能，作为AD检测接到Battery上就被拉高了导致进入BSL模式，程序无法运行，那么PA18如何复用为检测高电平的AD功能呢？

 

2、根据TI的文档说明，PA18的BSL_invoke功能可以被禁用，使用sysconfig配置为disable状态，用keil IDE编译烧写运行 并不起作用。Keil IDE并没有把BSL_CONFIG和BCR_CONFIG写入flash的nomain区域。参考“flashctl_nonmain_memory_write”例程，通过程序写入BSL_CONFIG和BCR_CONFIG配置参数到nomain区域，对于PA18被拉高的情况根本没有机会运行程序写入这两个配置来禁止GPIO BSL_Invoke功能，这种情况软件是否能够禁止GPIO BSL_Invoke功能？

 

3、我用“flashctl_nonmain_memory_write”例程写flash的nomain区域，禁止GPIO BSL invoke功能，Flash被锁死了 如何解锁？
