Hello,
I am using an nRF54LM20DK with nRF Connect SDK v3.1.1 and I am unable to establish I2C communication with an external DPS368 sensor.
The application starts correctly and the I2C bus is reported as ready by device_is_ready(). However, any I2C access fails immediately. The first call to i2c_write_dt() already returns an error, so no register read is possible.
The DPS368 is configured at address 0x77 on i2c30 via a devicetree overlay. Although the bus itself is ready, communication with the device does not work.
The SCL line is correctly clocked; this was verified using an oscilloscope.
Best regards
