CCS/LAUNCHXL-F28379D: How do i implement dual cpu codes

Hi,

I wanted to know if there is any specific way to run/ execute a dual cpu code. Should I add any predefined symbols or do any changes to debugging mode? I'm trying to implement dual cpu blinky code and it doesn't seem like it is implementing dual cpu.

Hi Silso,

Please import the project from

C:/ti/c2000/C2000Ware_3_02_00_00/driverlib/f2837xd/examples/dual/led/

This will import two projects, one for CPU1, and another for CPU2. You need to build, load and run seperately.

Okay, thanks! I have tried running the c2000 workshop code, available here(https://training.ti.com/c2000-f2837xd-microcontroller-1-day-workshop-series?context=1134645). I was able to impletment most of the code. However, I am unable to see any output at cpu2. There is no sine wave but only a straight line. Can you suggest me what I am doing wrong?

Which lab you are running from the workshop?

Are you able to load and run the binaries on CPU2? Can you set breakpoint on ISR?

Do you have jumper wire connected as per instruction in the workshop?

Yes, I added the jumper cable to it. However, I can see the output if i use the oscilloscope but not on the graph mentioned in the lab. Also, why is the implementation of this lab different than the dual blinky? The lab allows you to execute and debug cpu1 and cpu 2 separately but dual blinky needs to executed separately. AM I missing something?

You should be able to see the sine curve on ADCBuffer variable. I just tested it. What is the plat setting you are using?

Regarding implementation difference between Dual Blinky in C2000ware and Lab, the lab is based on bit-field implementation, while C2000ware is moving towards DriverLib implementation. You can continue using bit-field based implementation. Bit-Field based examples are located at:

It was never a straight line. SMH. I had to zoom and it was working fine all along.
