Problem with the reset.

[Ceda]

Hi,

I try to disable the reset mode and use the pin 0.18 as an normal input pin.

I'm using  nrf52840 development kit (pca10056).

Does someone have i idea to resolve this problem ?

Best Regards,

Hello,

I am looking into it, but I will have to get back to you over the weekend.

Hello Ceda!

Are you using NCS or nRF5SDK?

If you are using nRF5SDK, have you defined CONFIG_GPIO_AS_PINRESET in your preprocessor defines? That should be enough to reserve the pin for reset.

Hi Elfving,

No, i don't want to reserve the pin 0.18 (reset pin) for reset, so i undefined CONFIG_GPIO_AS_PINRESET. I want to use the pin 0.18 for another using.

I'm using nRF5SDK.

I see, I guess I misread your first post.

Could you run an erase-all or a recover, and see if that helps? This is being written to UICR, which won't be overwritten using for instance a "west flash".

Hi Elfving,

Ok, I will test the "west flash"  and I'll let you know the result.
