Part Number: TMS320F28377D
Other Parts Discussed in Thread: C2000WARE

Hello,
Could you please advise how to let CPU1 to stop the CPU2 execution and hold the CPU2 in reset state?

When I tried the followings, the CPU2 didn't stop toggling the LED.

Program the blinky_dc_cpu01&02 into the flash memories.
Power recycle to start CPU1&2.
Right-click the *.CCMXL and "Launch selected configuration"
Pause the CPU1
Select the CPU1 register CPU2RESCTL and write 0xa5a50001
CPU1 restart.

hi Hideaki,

The steps you mentioned are correct .

Can you connect to CCS and check if the CPU2 gets suspended ?
I used the code at c2000ware\device_support\f2837xd\examples\dual\blinky_dc & tried the same steps at my end and it works .

I did see that the cpu2 led stops toggling .

Regards.

Meghana,
Thank you very much. I can do it now.
(I needed to write CPU2RESCTL when the CPU1 is running.)

hi Hideaki,

Actually it worked in both CPU1 running and paused case.
Anyway good to know the running case works for you.

Regards.
