XDS 100 + reset from CCS

Tomas Kosan

Other Parts Discussed in Thread: TMS320F2812

Hello,

I have a problem with XDS100. I use XDS100 as a debugging tool with TMS320F2812 and it works well with one exception.

If I pres Ctrl-R in CCS, so I want reset running program, program is reseted immediately but hardware not. In my case hardware is counter as 6ch PWM generator.

Inverter is driven by these pulses and then asynchronous (induction) motor is driven.

If I initiate reset, program halts and stops modulating PWM which leads to overcurrent in cicruit.

Here is some pictures:

As last picture show, realtime mode debug solve problem but I don't want ot use it.

Why this problem exist in non-realtime mode while in realtime not ?

And how can I fix this ?

You may want to try posting this into the C2000 forum.

Just an idea, but I think the problem is that in realtime mode, your device keeps servicing the interrupts that you selected, which probably keep the pwm working. in non-realtime mode, the pwm is not serviced.

Just curious, but why would you not want to use realtime mode?

Thanks for answer. Your explanation is propably right.

Problem with realtime mode is that after reset, program run again. If I use reset i need program to reset and halt (as normal mode do) because I usualy reseting it due to error in code resulting in motor jumping around :) Maybe there is some option in CCS to change behavior of realtime mode, but I didn't find it.

Another thing is that i must first turn on realtime mode from menu.
