Part Number: MSPM0L1304

Hi Ti expert,

I using the J-Llink debugging with the MSPM0L1304, and my configure as below

I don't know why running the debug project and the delay time also stop on the DL_Common_delayCycles

There is my sample code. should I provide some configuration?

Looks the led not bright and the delay is hang.

while (1) {

delay_cycles(32000000);

led_on();

}

Thanks,

Ben

What's action of this "stop" ?

Also, in the ccxml file, you need to change the XDS110 to Jlink.

Hi Helic Chi

I have changed, but it's not working.

What's action of this "stop" ?

->it's mean stop on the function DL_Common_delayCycles

Do you have any suggestions?

Thanks,

Ben

That's normal.

Since you delay some time, CPU will always stop in delay because running delay takes 99% CPU time.

If you add any other function, makes your app code bigger, and change delay to small delay, CPU won;t stop here very often.

sorry, i'm confused, as below is my code, I just want to delay one sec. but look the function stop on the delay_cycles, and keep stops and cannot continue.

Does any configuration need to be modified?

while (1) {

delay_cycles(32000000);

led_on();

}

Add a breakpoint in led_on function, try to see whether CPU will hit that break point.

The add breakpoint is working on the main function.

Why let it continue, I can't see led off and sleep 1 sec then len on?

led_off();

delay_cycles(32000000);

led_on();

led_off();

delay_cycles(32000000);

led_on();

delay_cycles(32000000);
