even though I disable it in my chip configuration?
My design is not stable, resets under some situations, seems like a hardware issue.
I don't think it's necessary to pull up Reset pin after disable it. Could you tell me whether you had check the RCM_SRSn registers? If not, I suggest you'd better to check the RCM_SRSn registers after reset happens to figure out the source which cause MCU reset.
I'm looking forward to your reply.
For hardware design, it is better to add pull-up resistor to reset pin. As you know, there is a internal pull-up resistor in our MCU, but it is only a weak pull-up. So it is recommend to add external one. If your software can run well most time, only will cause reset sometime by unstable reset signal. I think it might cause by non-external pull-up resistor.
Hope my reply can help you.
