cc3200 can't start from flash

Hi Dong,

Here are the steps I use, pay particular attention to step 2 and 3 :-

1. Make sure the SOP2 jumper is present
2. Select the "sys/mcuimg.bin" 
3. Browse to C:\ti\CC3200SDK\cc3200-sdk\example*\Release and select the filename.bin file you want
4. Check the boxes for Erase, Update, and Verify
5. Then choose Operation => Program
6. Then hit the Reset button on the CC3200 LP if asked by UniFlash
7. To run the program now stored on the SFlash, remove the SOP2 jumper.

I hope this helps.

Glenn.

Thank you very much for the reply. I did all the steps but for some reason it still doesn't work. Should I do something in the code?

Hi Dong,

There shouldn't be anything required in the code, the same code should work in debug mode and on the SFlash.

Here are a few other suggestions:-

Make sure you have installed the latest service pack, which you can get from here - http://www.ti.com/tool/cc3200sdk

You will need the latest version of UniFlash for the CC3200 to install the service pack, you can get that from here - http://processors.wiki.ti.com/index.php/CCS_UniFlash_-_CC3100/CC3200_Edition

Can you check the Rev number on your LaunchPad, is it Rev 3.1 or Rev 3.2?

Glenn.

Hi Dong,

If the code is working fine with debugger, then it should run from Flash. Since you are also removing SOP-2 Jumper. Only thing I suspect is that .bin file didn't get flashed properly.

Did you observe any error while programming using Uniflash? What is the size of bin file.

Also Do you have any UART/LED indication in your application that can indicate running state of the program. This is to understand whether the program ran and went to some fault or it didn't even load from Flash

Hi,

One last thing that might happen is if the device was formatted in secure mode.

Have you used the Uniflash to format the device? if so, do you remember if you checked the 'secure' option?

Anyway, if none of the above suggestions work, please start over with Uniflash and make sure you format the device with 'secure' option unchecked. Please also capture the Uniflash log in the Console screen at the buttom and send it over.

Regards

Thank you for the reply.

I did check the items you guys listed and make sure they are correct. 

my main program is:

void main()
{
BoardInit();

//
// Pinmux for UART
//
PinMuxConfig();

//
// Initializing DMA
//
UDMAInit();

#ifndef NOTERM
//
// Configuring UART
//
//InitTerm();
#endif

//
// Start the SimpleLink Host
//
VStartSimpleLinkSpawnTask(SPAWN_TASK_PRIORITY);

//
// Start the GetWeather task
//
osi_TaskCreate(ControlTask,
(const signed char *)"Remote Control",
OSI_STACK_SIZE,
NULL,
1,
NULL );

//
// Start the task scheduler
//
osi_start();
}

Part of the main subroutine "ControlTask" is:

void ControlTask(void *pvParameters)
{
int iRetVal, i;
char acCityName[32];
int iStatus,result=0;
char cCommandString[7];

unsigned long ulDestinationIP;

DBG_PRINT("GET_WEATHER: Test Begin\n\r");

//
// Configure LED
//
GPIO_IF_LedConfigure(LED1|LED3);

GPIO_IF_LedOff(MCU_RED_LED_GPIO);
GPIO_IF_LedOff(MCU_GREEN_LED_GPIO);

//
// Reset The state of the machine
//
Network_IF_ResetMCUStateMachine();

//
// Start the driver
//
Network_IF_InitDriver(ROLE_STA);
GPIO_IF_LedOn(MCU_GREEN_LED_GPIO);

//
// Configure Timer for blinking the LED for IP acquisition
//
LedTimerConfigNStart();

Since I didn't see LED turning off, I know the code didn't even go to the GPIO_IF_LedOff function.

The size in Uniflash is:

[23:22:36] INFO: Downloading file "/sys/mcuimg.bin" with size 56848

Please help.

Hi Dong,

As mentioned by Kaushal, the code should not make any difference, the LED has likely confirmed that the program is not loading at all.

As Shlomi has stated the next steps should be "please start over with Uniflash and make sure you format the device with 'secure' option unchecked. Please also capture the Uniflash log in the Console screen at the bottom and send it over."

Hi Dong !

I have problem that you same. Can you training for me step-by-step. Thanks you very much !

Dear Dong,

In reply to your first post - "  I was trying to program a bin file I did for cc3200 using uniflash. However, even the programming is successful, CC3200load board can't start from flash after removing SOP2 pin. The program works fine if I use debug mode. The code I had is a modified version from one of the cc3200 examples. There is no html or anything, only .bin file needs to be loaded in. Please let me know if I did anything wrong",

When u create any .bin file (modified from the CC3200-SDK sample codes), in the Uniflash utility, just rename your file as "/sys/mcuimg.bin". Then follow the standard procedure. 

By doing this, u can flash and run your own .bin file on the CC3200.

Best regards.

Glenn, Kaushal,

   I have been having the exact same problem as Dong.  Are you sure there is no influence by how the bin file is created, i.e. from the project settings, that changes how this works?  As Dong wrote, starting from a sample project fixed the problem.  I have a project that was modified from the out-of-box application which is giving me the same problems.  I wrote my steps and Uniflash output below.

   Please advise, as this is really delaying my development progress.

Thanks,

Angelo

Programming steps through CCS (works OK):
1. Open project in CCS.
2. Launchpad (rev 3.2 with XCC3200HZ chip) is plugged in, with SOP2 jumper in place.
3. Press the Debug button, and press F8 to start the application. ---> Aplication starts normally.


Programming steps through Uniflash (does not work):
1. File->New Configuration
2. Press OK on Target Setup window
3. Set COM port
4. Press Format, leave options unchecked, 1MB capacity, press OK.
5. Select /sys/mcuimg.bin option and change URL to .bin file compiled by CCS during the above steps for the same project.
6. Check Erase, Update, and Verify options.
7. Launchpad (rev 3.2 with XCC3200HZ chip) is plugged in, with SOP2 jumper in place.
8. Return to CC31x Flash Setup and Control, and press Program.  Reset Launchpad when prompted.
9. Remove SOP2 jumper.
10. Open terminal emulator on COM port.
11. Reset Lanuchpad. ---> Application does NOT start

NOTE: If I perform the exact same steps above but use a precompiled bin file from the examples (e.g. C:\TI\CC3200SDK_1.0.0\cc3200-sdk\example\out_of_box\ccs\Release\oob.bin) in step 5, it runs the application as expected.

If I understand correctly, you looking to just run your binary in standalone mode, i.e. load the binary into SFlash and have it boot from that binary, without having to load the program into RAM through the debugger each time.  If you program the binary using Uniflash, it should work fine, but I did find one exception (and there may be others) where this didn't work.  I explained it here:  

http://e2e.ti.com/support/wireless_connectivity/f/968/t/397121

So check to see if you are trying to write to the console before UART is initialized.  This won't necessarily fail when using the debugger, but does prevent program execution when running from SFlash.

The differences I have with that project is that I am using a project I created myself and currently I do not know how to do the generation of a binary file in code composer studio. Once I know this I believe I canbdo the flashing.
