Problem with the reset.

Hi Ceda, sorry about the delay.

Could you tell me about your circuit and what you are trying to do? The pin might be in a float state.

Regards,

Elfving

Hi Elfving,

Thank you for your Help !

The pin 0.18 stopped functioning as a reset pin. But if i check the state with "nrf_gpio_pin_read" the status is still high. I think there is an interrupt on the pin that I can't find to disable it.

Regards,

Ceda

There doesn't seem to be anything written to this UICR. And with it 0.18 is still functioning as a reset pin for you? In what way are you still seeing this being an issue?

devzone.nordicsemi.com/.../uicrfile.hex

I have the same result with "nrfjprog -e -f NRF52".

I'm sendind to you the uicrfile.hex.

Hello again,

That is a bit odd. Could you try nrfjprog -e -f NRF52, and see if that gives the same result? If it does, could you run nrfjprog --readuicr uicrfile.hex, and send it to me?

Hi Elfving,

I tested "nrfjprog --recover" but the error still there.

CONFIG_GPIO_AS_PINRESET is undefined in my ide.

Hi Ceda,

If you are using SES I don't think this generally should be a problem.

Could you try to simply recover the chip with the terminal first, running "nrfjprog --recover", and then try to use SES like you normally would and see if the error is still there?

If it is, we would have to see if CONFIG_GPIO_AS_PINRESET is defined someplace else in your common configurations in SES.

Now, I'm using SES but i can use nrf command line if it's more simple.

Great, though I have looked at it some more and it might be that you have to do a "west flash --softreset" instead. Sorry about the confusion.

Are you using SES or a terminal command to flash the board?

Elfving

Hi Elfving,

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

Ceda

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,

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.

Ceda

Elfving — Mon, 07 Feb 2022 13:38:06 GMT

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.

Elfving

Hello,

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