CC3200 file operations

Hi,

Just to add on Raj's answer, the max. memory limit per file is 1MB (you can pick a serial flash up to 16MB).

All data is non volatile so it stays in the flash upon reset.

Hi thanga raj & Shlomi,

Thank you very much for your reply.

CC3200 file operations project worked fine.

Currently I have embedded these functions to our main application code. But while debugging the code, it get stuck at sl_Start (); function. It directly jumps to loader_exit(); function and prompts error message as

"ti.sysbios.knl.Semaphore: line 202: assertion failure: A_badContext: bad calling context. Must be called from a Task.

xdc.runtime.Error.raise: terminating execution".

I am also providing screen shots.

When I click on debug button and put cursor/arrow on sl_Start(); function, it shows following window.

Please anyone tell me, what will be the cause.

The function used in main.c file is as follows

//

// Initializing the CC3200 networking layers

//

lRetVal = sl_Start(NULL, NULL, NULL);

if(lRetVal < 0)

{

//GPIO_IF_LedOn(MCU_RED_LED_GPIO);

LOOP_FOREVER();

}

//

// reset all network policies

//

lRetVal = sl_WlanPolicySet( SL_POLICY_CONNECTION,

SL_CONNECTION_POLICY(0,0,0,0,0),

&policyVal,

1 /*PolicyValLen*/);

if(lRetVal < 0)

{

//GPIO_IF_LedOn(MCU_RED_LED_GPIO);

LOOP_FOREVER();

Are You using RTOS ??

Hi when you use RTOS ... you should call simple link task first in main, then You ought to call sl_start from any one of the task
you should not call it in main

Hi thanga raj,

Your reply found to be very helpful. I implemented the code as per your reply. It is running fine.

Thank you very much for your reply.
