TMS320F28388D: using debugger with 2 cores

Hi ,

You can have a single target configuration file (ccxml) which you can be used to connect to both C28 and CM cores.  You can then run the example on either of the cores . Don't think you can run the example on both cores at the same time .

CAN is a shared peripheral and can be allocated to either of the cores.  If CAN is allocated to CM, C28x CPU1/2 accesses to CAN will be ignored and interrupts from CAN will not be generated to C28x CPU1/2.

I do not work to use CAN from both cores :the 28 core does the configuration, and than enters a while(1) loop.

and the CM does the CAN code.

I am doing the below :

1) load and run the c28 code (runs from flash) : clear flash (cpu1) -> load program -> run

2) load and run the CM core (from flash) : clear flash(cm) -> load program -> run

does the above means both cores are running or does executing (2) stops the c28 core ?

Yes, both cores should be running.

Thanks,

In order to better understand the issue , I have decided to try out a TI demo.

I found a demo called led_ex1_c28_cm_blinky_cm.

The example consists of 2 projects. one for c28 and one for cm. each blink a led.

what are the stages to run this demo ?

how to I single step / add brake point the CM (I can do it for the c28 core, but could not do the same in the cm core).

I was able to load the CM code to RAM. I than loaded and run the c28 code , that booted the CM code and saw leds are blinking as expected. How do I debug the CM core ? add break point etc ?   

at his point , I can single-step and break point the c28 core. how to I connect to the cm core?

Hi,

You will have to connect to the "Cortex_M4_0" core.  You will have to select it in the debugger view and then connect to it. After connecting , you will be able to load the code and run.

Best Regards

when I right-click on the M4 and select connect I get this screen

what am I doing wrong ?
