Creation of files in directory/folder using xsdps driver of BSP

Hi,

I am using SD card application in my project, I have created standalone project and enabled Sdps in BSP.

I am able to create a directory using f_mkdir(const T_CHAR *path);.

I want to create files inside a directory, but there is no standard function to do so.

Please help me in creation of files inside the directory.

Regards,

Hello Praneeth,

I would start by looking at the Xilinx Xil FFS library functions and the FatFS file system if you want to implement a 'bare metal' file system:

Hello Gary,

Thanks for the reply, I am using the functions listed by elm-chan.org, but there is no function or an API to write files inside a directory.

Hello Praneeth,

I have not used the FatFS file system myself, but I see API calls to 'change current directory', 'open directory' , 'open/create file', and to 'write data'. What other API would you need?

Hello Gary,

I am able to create a directory. Open a file and write to a file outside the directory.I have also tried opening a directory using f_mkdir and f_opendir, but when I create a file after f_opendir function, it is exiting from the function. My application requires creating files inside a Directory. But it is happening separately.
