File system on nor flash

I want to use file system on nor flash. I am using fs_nor_flash_demo but in that I want to know that the API’s used inside demo like get hw info, mount FS, unmount FS. Do we have to write the definition of these functions by own or do quectel provides compiled library or something to help in this?

hello, sorry for late reply, could you please tell us your current firmware version? thanks~

Thank you for your reply, I have done with that. I found out the solution
