CC3200 Launchpad: Program changes behaviour after reset

Yves Willener

Other Parts Discussed in Thread: CC3200, UNIFLASH

I've just started playing with the CC3200 launchpad. I am using IAR EW and the TIStellaris Debugger for downloading my code. It works great, I can send MQTT packets to my mosquitto Broker.

There is just one little issue: whenever I unplug the usb cable (=power) or push the reset button the board stops and gets somehow stuck (uart communication dies and LEDs are not flashing anymore). So I assume its either not storing my program properly or it gets stuck after the restart.

After downloading the program again (with IAR) it works fine.. Do I need to do something special to flash the board permanently (i tried uniflash ond SOP Jumper combinations)?

Thank you for your advice.

Yes,

With TIStellaris Debugger you are downloading the code to SRAM for execution, hence, it is volatile.

You should use Uniflash to download the code to the serial flash.

This way, upon reset the code gets copied from serial flash to SRAM for execution.

You can see Uniflash UG on this link: http://processors.wiki.ti.com/index.php/CC31xx_%26_CC32xx_UniFlash

Thank you for your answer.

I tried that as well but without success. I have added the .bin file from my Project to uniflash as a userfile, formatted and programmed the board. After a reset the board still seems to be "stuck".

Am I doing something wrong with the flashing?

Hi,

The binary is a reserved system file and not a user file.

Please refer to the following chapter for clarification: http://processors.wiki.ti.com/index.php/CC31xx_%26_CC32xx_UniFlash#CC3200_support.
