Lockup on Reset Pin in VLLS2

leifzars — Mon, 30 Oct 2017 19:14:08 GMT

When in VLLS2 and the reset pin is hit, the System Reset Status Register reads a Lockup. This is using a Kinetis MK24FN1M (1N8B3J).

Previously using the MK20DN512 (5N22D) this did not happen, I would get a PIN reset code.

Anyone experience this, or know a work around?

Hi Leif,

I don't quite know what you mean 'lockup'. I made a test on my TWR-K24F120M. I download the example power_mode_switch by keil. In Project->option->debug->setting->Reset, I select 'reset pin'. Then I let the chip into VLLS2. Then I press the RESET button on KEIL. The SRS register will be 0x41.

Then in Project->option->debug->setting->Reset, I select 'Core and peripherals'. And do same operate as before, the SRS register read as 0x1.

So I didn't see any problem. Can you give more detail about your question?

Regards

Jing

In manual 6.2.2.9 Lockup reset (LOCKUP).

I must have something miss configured with my setup. Would you think the issue is on boot?

Any thoughts?
