LAUNCHXL-F28379D: LaunchPadDemo Program

Fahad,

Did you load the out file to CPU1 and CPU2 ? (CCS menu  Run -> load , select the demo binary for each core)?

Yes, I load the out file to CPU1 and CPU2

It does not go to main() function?

hi: Jha. 

I have same problem .   program can not run .   but when I use c2000ware 's  F28379D program blinky ,   it is can run . then I chang to duble core cpu02 to download" blinky cup02" , it can not download . and show :

"If erase/program (E/P) operation is being done on one core, the other core should not execute from shared-RAM (SR) as they are used for the E/P code.  Also, CPU1 will be halted to determine SR ownership for the CPU which will run the Flash Plugin code, after which CPU1 will be set to run its application. User code execution from SR could commence after both flash banks are programmed."

how can I do ?

best regard. 

Have you downloaded C2000ware SDK and installed? It can be downloaded from here

Then import the project from C:\ti\C2000Ware_2_01_00_00\driverlib\f2837xd\examples\dual\led.

Rebuild the project for CPU1 and CPU2, and try these binaries.

thank you Jha:

you have mention C2000ware SDK.  that is just a flope of document .  C2000ware_2_01_00_00 is saftware . so

1:I redownload it .  before , I download file vession is C2000ware_2_00_00_02 .  

2: I download ccs10 and run it .   before, i use CCS6.2. 

3: In complier , I add "porducts" -> "c2000ware" tool .

4: Import the project from C:\ti\C2000Ware_2_01_00_00\driverlib\f2837xd\examples\dual\led.

5: Build project CPU1 , chose cpu1 debugs .  it is can run , the led10 blinky.

6:Build project CPU2 , chose cpu2 debugs. it is can run ,but led9 can not blinky. at this time I hold the cpu1.  

7: I changed  "led_ex1_blinky_cpu2.c"  DEVICE_GPIO_PIN_LED2"  to "DEVICE_GPIO_PIN_LED1"   ,such as" cpu1.c"  , then download it to run ,  this time led cann't  run . 

8 : I set breakpoint in cpu2.c ,  program can stop at it's port.  that inpove it is runing . 

At end , I want to ask : if  cpu1 and cpu2 can not use same gpio or some other problem ?   ( 28379d launchpad xL）

best regard!

Hi,

If you have downloaded, the firmware for CPU1 and CPU2, then it should behave as follow

CPU1 will toggle DEVICE_GPIO_PIN_LED1 --> GPIO31 (D10, BLUE)

CPU2 will toggle DEVICE_GPIO_PIN_LED2 --> GPIO34 (D9, RED)

You have to load CPU1 first, and it sets master core for GPIO

//
// Configure CPU2 to control the LED GPIO
//
GPIO_setMasterCore(DEVICE_GPIO_PIN_LED2, GPIO_CORE_CPU2);

If you want CPU2 to toggle DEVICE_GPIO_PIN_LED1, then you need to make corresponding changes in CPU1 main() function to set the master core for GPIO and also in CPU2 code for doing actual toggling of GPIO. Then it should work.
