MPC5604 Reset Because OF CHKSTOP

[白金钟白]

When I use MPC5604（SPC5604PGMLQ6），I find it Reset sometimes but not ofen if the program run more than 12 hours 。I print the register RGM_FES ，the “F_CHKSTOP” is 1。

what reasons can lead to this ？

Hi,

the reasons for checkstop state are listed in the reference manual for e200z0 core:

https://www.nxp.com/docs/en/reference-manual/e200z0RM.pdf

So, the first step is to keep MSR[ME] enabled and IVOR1 machine check exception should be handled. If you don't have handler for IVOR1 yet, good start is to put just endless loop there, so you can check the reason for this exception, at least.
