'pin' is marked as deprecated in 'properties:'

[zciwor]

I am migrating from nrfConnect 1.7.1 to 2.3.0 and am getting a number of build errors. I have a custom board definition for my product and in it we've obviously defined custom pins for the peripheral devices.

For example: uart0

&uart0 {
	status = "okay";
	compatible = "nordic,nrf-uarte";
	current-speed = <115200>;
	tx-pin = <20>;
	rx-pin = <19>;
};

When building, I get the following error:

'tx-pin' is marked as deprecated in 'properties:' in /opt/nordic/ncs/v2.3.0/zephyr/dts/bindings/serial/nordic,nrf-uarte.yaml for node /soc/uart@40002000.
'rx-pin' is marked as deprecated in 'properties:' in /opt/nordic/ncs/v2.3.0/zephyr/dts/bindings/serial/nordic,nrf-uarte.yaml for node /soc/uart@40002000.

I understand that I need to use `pincntrl-0: <>` instead. However, I have no idea what pinctrl expects. I keep getting an "unknown node" error. What can I reference? Is there a migration guide somewhere? 

I am guessing that it should look something like this: `pinctrl-0 = <&uart0_tx_pa20 &uart0_rx_pa19>;` but I have no idea. Any help is appreciated.

I have found the migration guide here: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/app_dev/pin_control/index.html#ug-pinctrl

But after following the instructions, I am now getting the following errors:

Hi,

You also need to enable pinctrl in configs. In the defconfig file of the custom board, add CONFIG_PINCTRL=y.

Your pinctrl.dtsi file looks correct. Did you also add the pinctrl nodes to the UART and I2C nodes? They should be added to the node like this:

&uart0 {
	status = "okay";
	compatible = "nordic,nrf-uarte";
	current-speed = <115200>;
	pinctrl-0 = <&uart0_default>;
	pinctrl-1 = <&uart0_sleep>;
	pinctrl-names = "default", "sleep";
};

Best regards,
Marte

[zciwor]

Hi Marte, thank you for your quick response. I added CONFIG_PINCTRL=y to my prj.conf file and am still facing the same error. 

I can also confirm my what my uart0 node in the .dts file looks like: 

&uart0 {
	status = "okay";
	compatible = "nordic,nrf-uarte";
	current-speed = <115200>;
	pinctrl-0 = <&uart0_default>;
	pinctrl-1 = <&uart0_sleep>;
	pinctrl-names = "default", "sleep";
};

Although, I'm noticing that the error is just complaining about the UART driver, these changes seem to resolve I2C errors. 

Any ideas?

It seems to be complaining that the PIN_CTRL configuration is not enabled. But In build ./build/zephyr/.config file I clearly see 

CONFIG_PINCTRL=y

as well as other PINCTRL related configurations:

CONFIG_DT_HAS_NORDIC_NRF_PINCTRL_ENABLED=y

CONFIG_PINCTRL_STORE_REG=y

CONFIG_PINCTRL_NRF=y

I've tried deleting the build folder and running pristine builds. I'm not sure what I'm missing.

Okay, I figured it out. For some reason adding CONFIG_PINCTRL=y to the root .prj file did not work.

However, adding CONFIG_PINCTRL=y to the defconfig file in your ./boards/arm/customboard/customboard_defconfig file fixes it.

Here is what I used as a reference:

Hi,

I was having the same issue with a little different error.  It looked like in the PINCTRL Driver that the common.c routine was not getting compiled.  This was causing a couple of routines to not be resolved and getting a build error.  With CONFIG_PINCTRL=y set in proj.conf it should have been built.  But, as you commented above, putting that in the proj.conf did not appear to work.  That was recommended to me as well, although I had already tried that as a result of looking in the CMakeLists.txt.

Luckily, I saw your post of finding a hint by putting it in the device tree defconfig file and that did that trick for me as well.

So thanks for your digging into this. It would be good to know why it isn't working when put in the proj.conf file like you would think it should.

Thanks again,

h.
