SPC56EL60L3软件看门狗定时器复位没有运行

大家好，
使用SPC56EL60L3进行操作时，我注意到当软件看门狗定时器复位器件时，行为与我预期的不同。我期待应用程序重新启动，但我注意到应用程序没有开始运行，直到下一次上电复位。
查看设备文档，我找到了以下句子（第1292页，RM0032）：
'如果发生软件看门狗超时事件，则芯片将在复位退出后立即进入SAFE模式。
所以我找到了启动代码，我发现了这个（文件clock.c，第131行，函数spc_clock_init（））：
看起来当前运行模式是根据预期的运行模式（即DRUN）和if检查的

它是不同的，调用SPC5_CLOCK_FAILURE_HOOK（），它被映射到irqSysHalt（）（基本上是一个

无尽的循环）。这可以解释为什么我的应用程序在SWT重置系统后没有启动。


问题是：在SWT重置后，如果我需要重新启动应用程序（无需循环上电），该怎么办？

我是否可以更改上面的代码以包含SAFE_MODE作为有效的初始状态（以便功能继续）？

还有什么我需要做的吗？


谢谢。

问候

Hello Everyone,
woking with SPC56EL60L3, I noticed that when the device gets reset by the software watchdog timer, the behaviour is different than I expected. I was expecting the application to be restarted, but I notice the application does not start running, until the next power-on reset.
Looking at the device documentation, I found the followong sentence (page 1292, RM0032):
'If a software watchdog timeout event occurs, then the chip will always enter SAFE mode immediately after reset exit.'
So I Iooked at the startup code and I found this (file clock.c, row 131, function spc_clock_init() ):







It looks like the current run mode is checked against the expected run mode (which is DRUN) and if

it's different, the SPC5_CLOCK_FAILURE_HOOK() is invoked, which is mapped to irqSysHalt() (basically an

endless loop). This could explain why my application isnot starting after the system being reset by the SWT.


The question is: what if I need my application to restart (without having to cycle the power), after a SWT reset?

Can I just change the above code to include SAFE_MODE as a valid initial state (so that the function goes ahead)?

Is there anything else I need to do?


Thank you.

Regards

Alessandro
