Using NRF9160 with Flash Circular Buffer (FCB)

[ubieda]

Hey, everyone.

I am currently working with NRF9160, NCS V1.3.0, developing code for an application that requires periodically storing  important information in flash, and send the accumulated information whenever possible. I looked through the Zephyr libraries and came across with Flash Circular Buffer (FCB) and seems perfect for this use-case. 

I could not find an example code of its usage, though; I tried to put together a simple code following API instructions and fcb_init() returns negative error code (-EIO): I attempted to use "storage" partition. 

Could anyone, please, provide some guidance on how to use this library with the NRF9160 flash partitions?

Thanks in advance, 
Luis.

Take a look at ncs\v1.3.0\zephyr\tests\subsys\fs\fcb\src\main.c, which may give you some guidance on how to use the Flash Circular Buffer library.

It may also be worth taking a look at the NVS library and the sample ncs\v1.3.0\zephyr\samples\subsys\nvs\src\main.c

Best regards,

Simon

Hi - the link no longer works and there is no longer any \fcb\ directory under \subsys\fs - any other pointers?
