hello,

I need to create a folder in the SD card and copy the files into the folder.

I am able to create the folder but not able to copy the files into it.

And also if the folder is already present,it gives assertion fail.

Assertion @ Line: 195 in /source/vision/platform/ti/tda2/apps/src/rtos/modules/network_ctrl/network_ctrl_handle_mmc_wr.c: 0 == status : failed !!!

1. how to create a folder into the sd card?

2. how to change the directory to copy the files into the folder created?

Below is my code:

status = File_getcwd(cwd, (Int32)1000);

if(0 == status)

{

char godfolder[NETWORK_CTRL_CMD_STRLEN_MAX]={'G','O','D'}; // new folder :GOD

strcat(cwd, "/GOD");

System_linkControl(

linkId,

SYSTEM_LINK_CMD_MAKE_DIR,

godfolder, strlen(godfolder)+1,

TRUE);

status = File_chDir(cwd);

}

Hi Vijeetkumar,

Which version of VSDK are you using? I am supposing that the MAKE_DIR is a custom command you have added. If yes, can you please share your version of the network_ctrl_handle_mmc_wr.c(both pc side and evm side) file so that I can have a closer look at it :)

Anand

Hello Anand,

I am using PROCESSOR_SDK_VISION_03_03_00_00. But anyways folder is getting created now.

Thanks for the help.

I want one more help on deleting the folder.
I am using the below function:
status = File_delete(dirPath);

f_unlink(filename) is returning 7, which means access denied.
FR_DENIED, /* (7) Access denied due to prohibited access or directory full */

Note: I am able to delete the file with the same api but not directory.

Hi Vijeetkumar,

This is strange. The same api should work for both file or directory delete. Can you put a breakpoint in f_unlink() and step through to find out why exactly does it go to FR_DENIED? It could be due to attempting to delete a read-only dir/file, or other reasons like that. Meanwhile, I'll try to replicate this on my side.

Regards,
Anand

Hello Anand,

I cant find definition for f_unlink() and also debugging is slightly difficult for me as I am not using jtag. I putting print statements for debugging. if its denying due to read-only how to make it write?

were you able to replicate it?

Hi Vijeetkumar,

I have not yet been able to replicate the setup. Hmm. It is strange that you can't find the definition of f_unlink(). You should be able to find it in some of the fatfs library files. Then you can try putting printfs under each ifdef. I would recommend using a debugger though.

Anand

Hi Vijeetkumar,

Were you able to find the function f_unlink()? I believe you were able to fix the issue/you don't see the issue anymore?

Anand
