LSM6DSL is failing on custom board with NRF5340soc

I suggest to buy an LSM6DSL module and connect to an nRF5340 DK for further debugging, then you will also be able to connect a logic analyzer to the pins in questions.

Hi,

[quote userid="2111" url="~/f/nordic-q-a/115688/lsm6dsl-is-failing-on-custom-board-with-nrf5340soc/507117"]I suggest to connect a logic analyzer to the spi pins and irq, to see what data is actually sent/received. Just to check if it looks okey (clock toggle as expected, chip select go low, data on miso/mosi etc). Maybe some of the pins are not connected or setup correctly, maybe the sensor is not working/powered as expected.[/quote]

sorry that provisions are not available in our board

I notice you are using gpio port0 pin2, which overlap with nfc, so make sure you do the following in the overlay file:

&uicr {
nfct-pins-as-gpios;
};

Thanks for the input I tried but facing same error

Sorry that's my typo mistake in overlay it was fine

Thanks

Thanks

Thanks

Could you try the lsm6dsl sample just to see if it works as expected? You can also try to add

CONFIG_LSM6DSL_TRIGGER_GLOBAL_THREAD=y and

# Enable GPIO

CONFIG_GPIO=y

As I don't see anything wrong, can you draw me the wiring?

Hi,

Thanks for the response. Here I attached the thinks needed.

[quote userid="122502" url="~/f/nordic-q-a/115688/lsm6dsl-is-failing-on-custom-board-with-nrf5340soc/507048"]Which version of NCS are you using?[/quote]

I am using NCS V2.5.2

/* Check if device is initialized correctly. */
	if (!device_is_ready(imu_dev)) {

device_is_ready is getting failed

Hi I hope you have a great day!

I can't see anything that stands out so I have a few questions:

Which version of NCS are you using?

When you say it fails, which error do you get?

There are a number of Kconfig needed for the sensor which you can find here: https://docs.nordicsemi.com/bundle/ncs-latest/page/kconfig/index.html#!CONFIG_LSM6DSL have you added it to your prj.conf ? This will also include CONFIG_SPI=y and CONFIG_SENSOR=y

Please also provide the prj.conf
