LAUNCHXL-F28379D: CPU2 seems to stuck at _system_post_cinit() 0x3FE44F while the CPU1 stuck waiting to sync with cpu2

Part Number: LAUNCHXL-F28379D
Other Parts Discussed in Thread: C2000WARE

Tool/software:

I'm trying to create a dual cpu project that read adc, send it to cpu2 then send it through can, it works. But, when i try the standalone mode in flash the cpu2 seems to stuck in the address 0x3FE44F even after reset or power cycle ( i use blinking led as an indicator if cpu2 is working ).

i already call the IPCBootCPU2 like this

The cpu 1 stuck in trying to sync with cpu 2, but since the cpu2 stuck they seems to be in deadlock.

Hi,

Can you load the symbols and see where the code is getting stuck. It sounds like the two cores aren't synced up properly. You can reference the IPC examples in the C2000Ware SDK. Here's the C2000Ware IPC Lab: https://dev.ti.com/tirex/explore/node?node=A__AX4u1JCujNz1VnDNN1Wl9g__C28X-ACADEMY__1sbHxUB__LATEST&placeholder=true&search=ipc

Ensure that the CPU is initialized properly before trying to sync the cores.

You can also use this examples as a starting point: https://dev.ti.com/tirex/explore/node?node=A__AJ4WdWsk6cPkfdqV.gaWJQ__c2000ware_F2837xD_module_software_package__1kRFgrO__LATEST&placeholder=true

Regards,

Ozino

i already load the symbol but the assembly in cpu2 seems to have no difference it looks like this

if i see in the technical reference it looks like in the range of idle mode (CMIIW)

while the cpu 1 stuck waiting for sync flag

honestly, i'm just using the example in the device_suport path. if i use the example from your link do i have to convert the whole code to driverlib ? some of mine are still using bitfield

Hi,

There are some bit-field examples that you can use as a starting point. Where you able to run the examples successfully to see how the sync occurs and when the CPU2 is released?

ok i'll try to use the dual blinky as a starting point. sorry, but how do you see when the cpu2 released ?

Once the CPU2 is released, you should be able to hit the main while loop. At this point you should see LEDs blinking on the board. This indicative of a successfully running example.
