Zephyr WS2812 Driver undefined reference to `__device_dts_ord_68'

Hi,

You are posting in a ~1 year old case. If the below does not help, I would recommend that you open up a new thread.

[quote user="blue_dew"][00:00:02.977,630] <err> spi_nrfx_spim: Timeout waiting for transfer complete
[00:00:02.977,935] <err> app: couldn't update strip: -116[/quote]

The default timeout for a SPI transaction is 200 ms. This is set via. CONFIG_SPI_COMPLETION_TIMEOUT_TOLERANCE.

If you send a large amount of data over SPIM, you might need to relax this delay (to for instance 1000 ms).

Kind regards,

Håkon

Hello,

I am trying to use the same LED and below is my overlay:

&spi0 
{
        status = "okay";
        compatible = "nordic,nrf-spim";
        pinctrl-0 = <&spi2_default>;
        pinctrl-1 = <&spi2_sleep>;
        pinctrl-names = "default", "sleep";
        led_strip: ws2812@0 {
                compatible = "worldsemi,ws2812-spi";
                /* SPI */
                reg = <0>; /* ignored, but necessary for SPI bindings */
                spi-max-frequency = < SPI_FREQ >;
                /* WS2812 */
                chain-length = <1>; /* arbitrary; change at will */
                color-mapping = <LED_COLOR_ID_GREEN
                                 LED_COLOR_ID_RED
                                 LED_COLOR_ID_BLUE>;
                spi-one-frame = <ONE_FRAME>;
                spi-zero-frame = <ZERO_FRAME>;
        };
};

where pin controls are defined as this:

        spi2_default: spi2_default {
                group1 { psels = <NRF_PSEL(SPIM_SCK, 1, 10)>,
                        <NRF_PSEL(SPIM_MOSI, 1, 00)>,
                        <NRF_PSEL_DISCONNECTED(SPIM_MISO)>;
                };
        };

        spi2_sleep: spi2_sleep {
                group1 { psels = <NRF_PSEL(SPIM_SCK, 1, 10)>,
                        <NRF_PSEL(SPIM_MOSI, 1, 00)>,
                        <NRF_PSEL_DISCONNECTED(SPIM_MISO)>;
                        low-power-enable;
                };
        };

This works but when I try to use "NRF_PSEL_DISCONNECTED(SPIM_SCK)" the MOSI line does not send any data. The following message is given:

```
[00:00:02.977,630] <err> spi_nrfx_spim: Timeout waiting for transfer complete
[00:00:02.977,935] <err> app: couldn't update strip: -116
```

My understanding of the LED driver is that it only needs the MOSI pins and I would like to be able to utilize the other GPIO pins. Thank you for your help!

Hi,

It searches for led-strip in the DT, so you'll need to alias your status_leds to this:

led-strip = &status_leds;

Could you try this and see if it works?

PS: your mosi/miso pins are still set to P0.00.

Kind regards,

Håkon

Can you please share your full overlay file?

Kind regards,

Thank you for the tip regarding unused pin numbers.

I am trying to integrate the WS2812 driver into an existing project on a custom board.

After deleting the build directory, I noticed the following warning from CMAKE:

CMake Warning at D:/nrf_connect/v1.9.1/zephyr/CMakeLists.txt:764 (message):
  No SOURCES given to Zephyr library: drivers__led_strip

  Excluding target from build.

How do I resolve this?

RE: Zephyr WS2812 Driver undefined reference to `__device_dts_ord_68'

Hi,

Unused pins should be set to 0xFF (define NRFX_SPIM_PIN_NOT_USED). When you set them to 0, it implies P0.00.

I tried the example in path/to/ncs/zephyr/samples/drivers/led_ws2812

With the addition of these two files in the led_ws2812/boards/ catalog:

nrf5340dk_nrf5340_cpuapp.conf:

CONFIG_SPI=y

nrf5340dk_nrf5340_cpuapp.overlay:

/*
 * Copyright (c) 2019, Nordic Semiconductor ASA

 */

#include <dt-bindings/led/led.h>

#include "../nrf52-bindings.h"

&spi2 {
	compatible = "nordic,nrf-spim";
	status = "okay";
	/* Note that this pin is not routed to the gpio header on nRF5340-DK, it routed directly to the external flash */
	mosi-pin = <16>;
	led_strip: ws2812@0 {
		compatible = "worldsemi,ws2812-spi";
		label = "WS2812";

		/* SPI */
		reg = <0>; /* ignored, but necessary for SPI bindings */
		spi-max-frequency = <SPI_FREQ>;

		/* WS2812 */
		chain-length = <16>; /* arbitrary; change at will */
		color-mapping = <LED_COLOR_ID_GREEN
				 LED_COLOR_ID_RED
				 LED_COLOR_ID_BLUE>;
		spi-one-frame = <ONE_FRAME>;
		spi-zero-frame = <ZERO_FRAME>;
	};
};

/ {
	aliases {
		led-strip = &led_strip;
	};
};

This compiled fine at my end, but please note that P0.16 is directly connected to the external flash on the nRF5340-DK!

You should select another GPIO if using the DK.

Kind regards,

Håkon
