f_gets function in nef52 12.0 sdk issue

[Ankush]

Hi ,

I am trying to interface SD card with nrf52. For this I am using fatfs example of new 12.0 sdk. I can able to write the data to file but when I am taking the data from terminal using f_gets function I am getting following error:

Error[Li005]: no definition for "f_gets" [referenced from E:\NIRF52\SDK\nRF5_SDK_12.2.0_f012efa\examples\peripheral\fatfs\pca10040\blank\iar\_build\ 

What does it indicate? Can anyone faced this issue previously?

f_gets is defined if _USE_STRFUNC is defined as 1 or 2, see the documentation of the function here (the last section describe this). There it also says that f_gets is a wrapper function for f_read.
