Other Parts Discussed in Thread: UNIFLASH, CC3200

I used code from exocite garage

but in that following function not works

 lRetVal = sl_FsOpen((unsigned char *)CIK_FILENAME,
                        FS_MODE_OPEN_READ,
                        &ulToken,
                        &lFileHandle);
    if(lRetVal < 0)
    {
        lRetVal = sl_FsClose(lFileHandle, 0, 0, 0);
        ASSERT_ON_ERROR(FILE_OPEN_READ_FAILED);
        return FALSE;
    }

and lRetVal gives me value -11 in place of 0.

Hi Pulkit,

What do you mean "Once i format flash after this function not works...". Explain more clearly.

Do you mean after doing Uniflash format the program do not work?

If you did a Uniflash Format, the program in the Serial Flash of your CC3200 Launchpad will be erased. So, the program won't run on next power cycle. The instruction how to make the Exosite CC3200 Cloud Demo work can be found at the link below.

yes actually i forget to tell that after format the flash i again upload code.
I put launchpad in debug mode and it says me error in file read.
I got retvalue -11 of "sl_FsOpen()" function.

Hi,

Explanation of issue is quite simple. You are opening file which is defined by macro CIK_FILENAME for reading. But this file is not available on your flash filesystem because you format it. You need save this file to your flash. I expect this is file with name "exosite_cik.txt".

-11 = SL_FS_ERR_FILE_NOT_FOUND

Hi,

Sorry, I don't know how this Exosite demo works. Maybe this file is written internally, I don't know. I just want to explain, what mean error -11.

Hi Pulkit,

For this example program "Exosite CC3200 Cloud Demo", The CIK or Client Interface Key, will be provided to you by Exosite and will be stored at Serial Flash.

Do these steps below. Place a jumper at SOP2, before doing any Uniflash Operations.

1. Using Uniflash format your CC3200 LP with settings 1MB Size, Secure and Alert option left unchecked.
2. Follow the steps at this link. github.com/.../README.md
3. At step 14 at README.md . First delete any existing device at Exosite then do step 14.
