littlefs - SPI1 dead

[okwestern]

I just cloned the latest zephyr from github and tried littlefs. However, the SPI pins have no traffic and CS line stays unchanged.

&spi1	 {
	compatible = "nordic,nrf-spim";
	status = "okay";
	sck-pin = <7>;
	mosi-pin = <5>;
	miso-pin = <6>;

	cs-gpios =	<&gpio0  8 GPIO_ACTIVE_LOW>,
			<&gpio0  9 GPIO_ACTIVE_LOW>,
			<&gpio0 15 GPIO_ACTIVE_LOW>,
			<&gpio0 19 GPIO_ACTIVE_LOW>;

[... three other spi drivers... then the fourth, my SD card driver...]

        sdhc3: sdhc@3 {
                compatible = "zephyr,mmc-spi-slot";
                reg = <3>;
                status = "okay";
                label = "SDHC0";
                spi-max-frequency = <24000000>;
        };
};

Is there something I forgot, since I can't see anything on SPI1?

If the device tree looks correct for littlefs, what else could it be?

For later reference, how do find the correct "compatible = [xxx]" in the driver source, so I can match the device tree instance with the driver/sample I want to test?

Hi,

It sounds like you are not using our SDK, and that this is an issue you would have to contact the Zephyr Project team about.

If you download and use the nRF Connect SDK, then I will be able to provide you with support. I recommend installing the SDK using the Toolchain Manager in nRF Connect for Desktop.
