nRF52832 with SK6812 LEDs

Hello,

I tried to run the example code for the ws2812 (which can be found at C:\ncs\v2.4.1\v2.4.1\zephyr\samples\drivers\led_ws2812) for the nRF52832 using nRF Connect SDK (v2.4.1).

Looking at the nrf52dk_nrf52832.overlay, it looks like MOSI would be used on P0.23.

&arduino_spi { /* MOSI on D11 / P0.23 */

I am trying to experiment using the nRF52 DK board. 
I have a known working LED ring which lights up from another board.

The code builds fine but when I run it, I see the following in the terminal.

Using a Saleae Logic analyzer, I don't see anything on P0.23. 

I tried adding the following from nrf52dk_nrf52832.dts but I ended up with the same message in the terminal and didn't see anything on the logic analyzer.

I tried multiple pins and couldn't see any changes on the IO lines that looked like the required signal for the WS2812 LEDs.

&spi2_default {
    group1 {
        psels = <NRF_PSEL(SPIM_SCK, 0, 25)>, <NRF_PSEL(SPIM_MISO, 0, 24)>,
        <NRF_PSEL(SPIM_MOSI, 0, 12)>;
    };
};

Has anyone had success with the WS2812 or SK6812 with the nRF52832 and nRF Connect SDK?

Thanks.
