Hello again,

I do not have this (FRDM-STBC-AGM01) board with me to test, but I have few observations as per the information you have shared:

1) What are the I2C pins in your DTS & overlay?
I do not see pin information in your overlay.
For example, below I share is a snippet from the compiled DTS of nrf52840 and we can see that the pins are assigned through zephyr PINCTRL Api. We can see that SDA and SCL pins are P0.26 and P0.27 respectively. So your DTS should match with your hardware pins connections.

2) Similarly, on the schematic of the board, we can see that INT1-8700 is pin3 INT2-8700 is pin5 on your board that is connected to Auduino-Header pin3 and pin5 (P1.04 and P1.06 of the DK) respectively. But that is not the case in your DTS.

3) Third would be making sure that i2c addresses are correct as per the datasheet.

BR,

Naeem

Hello Noaem,

Thank you for your prompt response earlier. I'm currently working on the project, and I'd like to share the DT code and a picture of the board with you. Your feedback and input would be highly appreciated.

Hi Marco,

Thank you for contacting DevZone at NordicSemi.

How does your DTS/Overlay look like, and how is your shield connected to the DK?

It will be nice if you could explain your pin connections and show hardware setup by attaching a snap.

Looks like the device (nxp_fxas21002) is present in the DTS but is not ready.

The error: <err> i2c_nrfx_twim: Error 0x0BAE0001 occurred for message 0

is NACK (not acknowledged) error meaning device is not responding as it should.

The error is discussed here as well.

Please make sure your pin connections are correct, slave address is correct, and the device is powered up.

BR,

Naeem
