CPU cannot be halted

[polimarte]

Hi to everyone!

I am using nRF52832 driven by nRF52 DK and a sensor from Maxim Integrated. As debug output i am using the RTT viewer and as IDE Keil.

When i run my code it seems to work properly but when i use the sensor (it is a like a photodetector and a led, so when i move the finger on it this will cause an interrupt) the outputs on the RTT viewer stops and i ends up to the "**JLink Warning: CPU could not be halted" warning as shown:

 

Even if the output of the RTT stops i can see that the sensor is continue to work properly, when my finger is detected a led  is set high. 

Where this error come from? Is it a problem of the RTT window (LOG) only? if it is not, why my sensor continue to work as defined?

Thanks,

polimarte

Hi,

Could be that the chip resets due to an error. Please have a look at the debugging procedure described in this thread, and see if that helps with your problem.

Best regards,

Hi, i know the debug procedure in keil. The problem is  that i am not getting any error. I run my code till the first interrupt that is called when my finger is detected, and than i have this behavior.

thanks,
