flashlog backend for nrf51

[Kainat Altaf]

I want to write my application logs to the flash. I am following this tutorial which is for nrf52: https://jimmywongiot.com/2020/02/24/print-log-flash-log-crash-log-on-nordic-nrf5-sdk/2/.  However, there is no nrf_log_backend_flash.c file in my SDK. Is there any example for nrf51 which I can follow to write logs on flash?

Thanks.

Hi,

Flash and Crashlog backends for NRF_LOG was added to the SDK in version 15.0.0, see the release notes. The last SDK version to support nRF51 was SDK 12.3.0, which means that these logger backends are not supported.

You can try to backport the backends to older SDK versions, but there may be too many changes between 3 major SDK version for this to be a trivial task.

Best regards,
Jørgen
