CCS/CC3200-LAUNCHXL: Program is lost after reset

Part Number: CC3200-LAUNCHXL
Other Parts Discussed in Thread: UNIFLASH, CC3200

Tool/software: Code Composer Studio

Hi,

I load my CC3200-LauchXL with CCS's blinky example.

It works fine while in debug mode, but when I press the reset button, the blinky program does not execute anymore. Instead, the board starts the default oob program.

I tried with success to use CCS UniFlash Version: 3.4.1.00012 to load the bin file at 0x2000 0000 address, but after a reset the problem persists.

Is there a way to load the programa correctly?

Thanks.

Hi Marcelo,

Uniflash programs the content to the external flash. Then upon boot it will be loaded to and run from the CC3200 RAM.
When you reset the board (using the RESET SW1) the RAM will get lost.
You can use the CCS debug buttons to reset and restart the MCU without losing the RAM content (and without reloading the flash code).

Br,
Kobi

Hi Kobi,
you are right about CCS buttons, but Uniflash has the same behavior.
I need to know how can I load a program into a flash memory (internal or external). I need turn off the board and turn on again without a computer plugged in.
I saw that there are SOP jumpers to change the boot behavior, then I tried use them. Unfortunatelly the result is the same.

best regards,
Marcelo

Hi Marcelo,

SOP2 should be when you are using the uniflash,
Take the jumper off when you want to boot from flash.
Make sure you are following the uniflash instructions (processors.wiki.ti.com/.../CC3100_&_CC3200_UniFlash_Quick_Start_Guide).

Hi Kobi,

the default oob is stored at internal ROM memory or external flash?

My uniflash haven't the option of "CC3x Serial (UART) Interface" when I press "New Configuration", instead I use "Stellaris in-Circuit Debug Interface" ( processors.wiki.ti.com/.../CC3100_&_CC3200_UniFlash_Quick_Start_Guide). My uniflash version is 3.4.1.00012.

Hi guys,

When I did my first Uniflash instalation I checked a lot of check box and for some reason "CC3x Serial (UART) Interface" didn't appear. I reinstalled the application using only the default configuration and now I have this option.
Now I can load my program to the external flash memory.
Thanks.
Marcelo
