Part Number:MSPM0C1104-Q1
Through the configuration software, SWD is disabled, but the program of the original chip cannot be erased when the power-on reset and the REST pin is pulled down,haven't been able to complete the connection, we are using jlink. Is there any solution?

上面的是,我重新上电,然后拉低rest引脚,然后使用jlink的命令行去连接MCU,进行擦除的报错log。

你好,我看了一下文档,有几个疑问,第一个3.1是让从低功耗模式下退出,我是将debug enable on swd pin失能了。才不能使用swd的。还有这个要配置位,你们用什么工具配置这些位的?如何配置的?

另外请问下,上电与拉低rest,发送命令行的时序如何
