in nRF54L15 getting I2C error code as -5, unable to communicate with I2C peripheral.

Hi Team,

Below function returns error code as -5 and unable to write and read data from I2C peripheral.

err = i2c_write_read(i2c_dev, addr, write_data, write_size, read_data, read_size);

#define  EIO 5    /* I/O error */

Can you please provide your inputs to resolve this I2C issue.

Regards,

Hi Rikka,

Did you already solve your issue?

How does your overlay file look? I had the same error and solved it by modifying my overlay file from

compatible = "nordic,nrf-twi";

to

compatible = "nordic,nrf-twim";

and that did it. The issue seems to be the “nordic, nrf-twi.”

&i2c0 {

    compatible = "nordic,nrf-twim";

Kind regards, Dani
