TMS320C6678: Reset one core from another core

Hi

But local reset as said in section 2.2.3 at sprugv4c power slip controller pdf

Is intended for watchdog timer and we would like to use it when no watchdog is activated.

Hi,

Local reset can be done in several ways: if you don't have WD, there is also "• LPSC MMRs (memory-mapped registers) " for this purpose.

Hi Eric

How do i debug that i did the reset properly and core that was reset did reset.

Hi,

If a core is in local reset, you can't connect it with CCS/JTAG.

Regards, Eric

Hi Dear Eric

Will other cores be able to connect?

if core 0 reset on core 1 how do we know that core 0 is still continue to function without resetting itself.

Hi Eric

Can we initiate a software local reset

To one of the cores as mentioned above ?

Since section 7.5 is about pin configurable local reset.

Hi,

7.5.4 Local Reset:

• LPSC MMRs (memory-mapped registers)

Yes, you can use software to do a local reset via LPSC domain registers.

Hi Eric

On section 7.5.4 there is no much information on
How to do a software local reset on a specific core from another core.  

On table Table 7-9 last row
MMR bit in LPSC controls C66x CorePac local reset. Used by watchdog timers.

does it mean that the LPSC register will be used in the WD and not accessible as you wrote for software local reset.?

It would be best if you can provide software example for software core reset initiated by other cores.
