NRF54L10: I2C configuration error

[payalD]

Hello Team,

I'm using nrf54l15 dk and ncs version 2.9.0 for the development. I am getting an error while configuring I2C. I selected i2c20 from the device tree and assigned P1.00 for SCL and P1.01 for SDA. It generated the following code in the nrf54l15dk_nrf54l10_cpuapp.overlay file

&i2c20 {
	pinctrl-0 = <&i2c20_default>;
	pinctrl-names = "default";

};

&pinctrl {
	i2c20_default: i2c20_default {
		group1 {
			psels = <NRF_PSEL(TWIM_SDA, 1, 1)>, <NRF_PSEL(TWIM_SCL, 1, 0)>;
		};
	};
};

Added the following configuration in the prj.conf file

CONFIG_I2C=y

CONFIG_PINCTRL=y

And wrote the following code to initialize I2C

#define I2C_NODE        DT_NODELABEL(i2c20)
const struct device *const i2c_dev = DEVICE_DT_GET(I2C_NODE);
const uint16_t i2c_addr = 0x68;
const struct i2c_dt_spec *i2c_spec;

i2c_spec = I2C_DT_SPEC_GET(I2C_NODE);

I'm getting the following error

devicetree error: 'pinctrl-0' is marked as required in 'properties:' in C:/ncs/v2.9.0/zephyr/dts/bindings\i2c\nordic,nrf-twim.yaml, but does not appear in <Node /soc/peripheral@50000000/i2c@c6000 in 'C:/ncs/v2.9.0/zephyr/misc/empty_file.c'>

Kindly help me resolve the error.

Regards,

Payal

Hi,

 

P1.00 / P1.01 is by default used for the external LFXO. If testing on a DK, you should choose other pins.

I am testing blinky, with your proposed overlay file in ncs v2.9.0, and I am unable to see this issue when compiling for nrf54l15/nrf54l10/cpuapp.

 

Have you done any board-related changes in the zephyr/boards/nordic/nrf54l15dk catalog? If yes, try reverting those.

 

Kind regards,

Håkon

Hi,

I tried configuring P1.02 for SDA and P1.03 for SCL. Now I am getting the following error.

CMake Error at C:/ncs/v2.9.0/zephyr/cmake/modules/FindDeprecated.cmake:40 (if):

While compiling the blinky sample for nrf54l10, I didn't add the .overlay file, but still I was getting the error.

No, I didn't change anything in the zephyr/boards/nordic/nrf54l15dk catalog.

While compiling any of the sample codes for nrf54l10 (not including .overlay file), I am getting the "devicetree error: 'pinctrl-0' is marked as required in 'properties:' in C:/ncs/v2.9.0/zephyr/dts/bindings\i2c\nordic,nrf-twim.yaml, but does not appear in <Node /soc/peripheral@50000000/i2c@c6000 in 'C:/ncs/v2.9.0/zephyr/misc/empty_file.c'>" error

Hi,

 

Glad to hear that you got that sorted!

Based on that build error message, it seems that there's defined a default and sleep pinctrl state, but not declared a sleep pinctrl entry.

 

Here's a suggestion (feel free to change the pinout):

&i2c20 {
	status = "okay";
	pinctrl-0 = <&i2c20_default>;
	pinctrl-1 = <&i2c20_sleep>;
	pinctrl-names = "default", "sleep";

};

&uart20 {
	status = "disabled";
};

&pinctrl {
	i2c20_default: i2c20_default {
		group1 {
			psels = <NRF_PSEL(TWIM_SDA, 1, 11)>,
				<NRF_PSEL(TWIM_SCL, 1, 12)>;
		};
	};

	i2c20_sleep: i2c20_sleep {
		group1 {
			psels = <NRF_PSEL(TWIM_SDA, 1, 11)>,
				<NRF_PSEL(TWIM_SCL, 1, 12)>;
			low-power-enable;
		};
	};
};

 

Kind regards,

Håkon

Hi,

Tried your suggestion. I got the following error.

Hi,

 

And how does your .overlay file look now?

It seems that you're lacking the pinctrl-1 entry, based on the error message.

 

Kind regards,

Håkon

Hi,

Håkon Alseth said:

Yes, the pinctrl-1 entry was missing; adding it successfully compiled my code.

Thanks for the help.

I have one doubt when I configured P1.12 and P1.14 for SDA and SCL, in devicetree.

Only the code below is generated in my .overlayfile

&pinctrl {
    i2c21_default: i2c21_default {
        group1 {
            psels = <NRF_PSEL(TWIM_SCL, 1, 12)>, <NRF_PSEL(TWIM_SDA, 1, 14)>;
        };
    };
};

&i2c21 {
    status = "okay";
    pinctrl-0 = <&i2c21_default>;
    pinctrl-names = "default";
    zephyr,deferred-init;
};

Can you help me understand why pincntrl-1 entry code and 

i2c20_sleep: i2c20_sleep {
group1 {
psels = <NRF_PSEL(TWIM_SDA, 1, 11)>,
<NRF_PSEL(TWIM_SCL, 1, 12)>;
low-power-enable;
};
};

is not generated?

Are there any additional settings for this?

Thanks,

Payal

[Håkon Alseth]

Hi,

 

You are currently using i2c21 and not i2c20, so this entry will not be used:

Hi,

Understood. But for i2c21 below entry should be generated

i2c21_sleep: i2c21_sleep {
group1 {
psels = <NRF_PSEL(TWIM_SDA, 1, 12)>,
<NRF_PSEL(TWIM_SCL, 1, 14)>;
low-power-enable;
};
};

Right?

Why is it not generated when I configure i2c21 in the devicetree?

What is the significance of this entry?
