ESTOP0 Problem in C2000 Debug Mode

Other Parts Discussed in Thread: TMS320F28035

Hi, Does anyone know how to solve a ESTOP0 problem?

When I go into debug mode in CCS for TMS320F28035, the program will sometime be suspended with an ESTOP0 symbol is not available problem. It does not happen all the time, so I am wondering if there's some setting or sequence that I need to change? 

Any help/ideas/pointers will be much appreciated.

Thanks!

    You may have an interrupt that is enabled for instance in the PIE that fires and causes this problem. If using DSP/BIOS this is common because all Ints are setup for HWI_unused and have an associated ESTOP in the function for debugging purposes. To find out which one change the INT's so that they each have there own handler. This allows you to know which interrupt has caused the ESTOP.

    John, Thanks for the quick response.

    I am very new to all this and will need to dig in PIE, HWI_unused,etc. 

    I have the TMDSHVMTRPFCKIT high voltage motor control kit and was running their sample codes when I get this.

    Hi, John,

    I met the same problem. And could you please tell me how to find out the one change the INT's and how to fix it?

    Thank you.

    I found a way to solve the problem. It may be the program's problem and if you can not find the INT, you can just use your backup program and be careful to test it according to the Doc. That will be all right.
