    Hi,

    you can find example how to use this functionality in vision_sdk/links_fw/src/rtos/links_common/null/nullLink_tsk.c or as alternative you can use Null link in your usecase to write file to SD Card (you can check vision_sdk/apps/src/rtos/usecases/null_src_mpeg4enc_null usecase for example).

    Also please check vision_sdk/links_fw/src/rtos/utils_common/include/file_api.h for description of File_XXXX functions.

    (note that file_api functionality is used when you run VisionSDK in BIOS on all cores mode, if you run Linux on A15, then file operations on SD Card are controlled by the Linux)

    Regards,

    Yordan
