debug problem when pmic is not in debug mode

ChangruiKhoo — Tue, 07 Apr 2026 02:55:20 GMT

我使用的是S32K388芯片，并且使用了pmic FS26（MFS2633HMDC3AD）
我遇到了这样的问题，当我的pmic不属于debug 模式时，我无法通过调试器MULTI LINK debug mcu S32K388，这是否正常呢，
我的pmic的mcal配置如下，我关闭了看门狗的reaction，问题还是存在

Re: debug problem when pmic is not in debug mode

当你把debug pin接到GND的时候意味着active WD，也就是说在SBC进入INIT阶段以后你必须在256ms以内喂狗配置好INIT相关的register，否则RSTB会周期性的拉低导致你的MCU无法正常的工作。

你看看下面附件attached的图片讲这个WD喂狗时序的。

我在256ms内成功喂狗了，当前处于正常运行的状态。在这个状态下我再次使用jatg进行debug，发现了上面我提到的问题。所以是因为jtag debug 也会复位PMIC吗，这导致需要重新在256ms内配置pmic

那你要去测试核实jtag debug会不会影响到FS26 的RSTB。
