Hi  I have created one simple project for TMS570ls04 launchpad for verifying RTI module and it is working , here in this project i have added one counter variable for verifying ISR but it is not continuously updating (continuous refresh is on ) and when i pause the program i am getting updated value .

Even for other variables same thing is happening . please hep me .

Thanks.

    Hello Indrajit,

    The TMS470LS0x32 devices do not have the connection between the DAP and the AXI bus to provide a continuous refresh of the data when executing in debug mode. i.e., this feature is not supported on this device. You must halt the CPU to see the value updated. This is one of the concessions made on the low end of the Hercules family in regard to performance and feature set.

    Thanks . I got it.
    Hercules does not support real time mode that is main reason .
    But can we monitor SCI received data in watch variables without halting processor.
    thanks.

    The RM41x\42x and TMS570LSx32 devices do not support any real time update of data within the debug environment. You must halt the CPU in order to update values displayed in the debugger including SCI receive values stored in RAM. You may be able to setup an echo function where received values are echoed back on the SCI line to a terminal window to monitor during run time.
