Are you able to probe the i2c lines with scope/logic analyzer to see if the clock and data signals look ok?

I do not get any i2c warning after enabling the logging. I do get the message:
"Failed to write / read I2C device address 50 at Reg. 34"

Which is caused because this if condition fails:

if (i2c_write_read_dt(&dev_i2c, &uiReg, 1, s_ucWitDataBuff, usTemp) == 0)

What I can't figure out why this fails particularly for nRF5340.

Hello,

Do you see any warnings/errors reported by the i2c driver if you enable logging by adding CONFIG_LOG=y to your prj.conf file? Also, do you have external pull-ups on this bus?

Best regards,
