Hi Duncan,

From what I have seen, the EEPROM library is one of the Zephyr libraries and not the Nordic-specific ones. I think you should try contacting the Zephyr developers directly via their Discord or mailing lists.

Best regards,

Michal

Hi Michal,

no problem. I have given up trying to use the eeprom library and hardcoded my own drivers for the device. It would be good to eventually get a solution to the issue as I might want to use it in the future. But for now I can manage.

Cheers

Duncan

Hello Duncan,

Sorry for the delay, I did not progress much with this yet.

Please let me know if you had managed anything in the meantime.

Best regards,

Michal

Hi made that change and still can't get the at25 eeprom reading or writing using the Zephyr eeprom sample.

Hello Duncan,

I see that under the at25db0 devicetree you have

status = "ok";

Could you change it to

status = "okay";

and see if it changes anything?

Best regards,

Michal

Hello Duncan,

Could you include your generated "build/zephyr/zephyr.dts" file as well as the "build/zephyr/include/generated/devicetree_generated.h" from your project?

Thanks,

Helmut Lord
