AWR1642: Runtime error & execution terminated after some time

Varsha Vanga
Expert 1010 points
Part Number: AWR1642

Hi Experts, 

I am running the object detection demo from the industrial toolbox with some configurations tweaked.

I am inserting a plain C function with some lines of code.

The configurations are: 

-------------------------------------------------------------------------

sensorStop
flushCfg
dfeDataOutputMode 1
channelCfg 15 3 0
adcCfg 2 1
adcbufCfg -1 0 0 1 0
profileCfg 0 77 360 7 57.14 0 0 70 1 256 5209 0 0 30
chirpCfg 0 0 0 0 0 0 0 1
chirpCfg 1 1 0 0 0 0 0 2
bpmCfg -1 0 0 1

calibDcRangeSig -1 0 -5 8 256
extendedMaxVelocity -1 0
clutterRemoval -1 0
compRangeBiasAndRxChanPhase 0.0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0
measureRangeBiasAndRxChanPhase 0 1.5 0.2
nearFieldCfg -1 0 0 0
CQRxSatMonitor 0 3 4 127 0
CQSigImgMonitor 0 63 8
analogMonitor 1 1
lvdsStreamCfg -1 0 0 0
sensorStart

----------------------------------------------------------------------------

While executing the demo, after processing of some frames,  I get the following error:


In My_func: START
In My_func: END

In My_func: START
In My_func: END

In My_func: START
In My_func: END

In My_func: START
In My_func: END

{module#8}: "../dss_main.c", line 345: error {id:0x10000, args:[0x8182a4, 0x8182a4]}
xdc.runtime.Error.raise: terminating execution
[Cortex_R4_0] xdc.runtime.Main: "../mss_main.c", line 2134: assertion failure
xdc.runtime.Error.raise: terminating execution

Can I know what is causing the error? Why is it crashing after some time? Memory related issue?

Regards,

    Hi Varsha,
    If added new code eats up some time and blocks DSS there then while doing the FFT for chirp/frame it may hit the assert in the chirp/frame-intHandler function where it check if last chirp/frame processing is done are not.
    So, please calculate new code time consumption.

    Hi Jitendra, 

    Yes, as you said it hits the assert in the frame int handler & fails there. The code I have added is a plain function with no long processing, it just adds the 2 numbers & prints it.  I have used the _itoll(TSCH, TSCL); to calculate the cycles of the function. 

    Following is the screenshot which shows my error: 

     

    Can you please help me with this.

    Regards,

    Varsha

    Don't add any system_printf (to CCS console), even though there is much code to execcute but printf to console function causes much more delay to execution flow. As for this print CCS intermettently halt the core and reads the value (if any) for printf, which effectively cause the delay and core will hit the assert.
    So, avoid adding any system_printf fuction when FFT processing is ongoing.

    Hi Jitendra,

    Thank you for your response. Yes, I will avoid using prints to the console.

    Hi Jitendra, 

    Could you please let us know the method to check a particular value as we cannot print it on the console ? 

    Your response will be appreciated. 

    Thanks in advance.

    You can use DSS/MSS UART-print to output the variables to the PC serial terminal.
    If you want to use DSS UART, it comes on DevPack FTDI COM port (3rd USB COM port) and MSS has two UART which you use.
    You can get code reference from UART driver test application (packages\ti\drivers\uart\test\xwr16xx) to add DSS UART into your application.

    And if you need to just measure the execution time by any function then better to add those timestamp value in some global variables and after few frame run halt the core and extract the value (or array of values) from CCS. Note- in this case DSS may go into fault when you halt and run it again, so you need to provide much time to get all the expected timestamp values updated for your measurements.

    Hi Jitendra, 

    Thank you for the quick response. I will look into it & get back to you. From surfing through the forum , I came across things like DebugP_log1 and Log_print1. Can I use them to get the stuff on the console? Will these cause the issues like that of delay ....?

    Hi Varsha,
    On top of last suggestion, I would request you to go over mmWave SDK User guide (section -6) where it has miscellaneous information about CCS Debugging of real-time application. There it explains how to enable DebugP logs.

    Hi Jitendra,

    I am able to enable DebugP logs. I have put the number of entries to 100(As per document this was causing memory issues,so I have reduced it). But the issue is I can see the values in ROV, but when I refresh it more than once, I get following errors in CCS Console:

    Same is the case when I enable "Repeat Refresh". I want to check the constantly changing variables.

    Can You help me with this?

    Are you using the real-time mode in CCS (there are real-time icons at the top)? Please see the notes in the section Jitendra mentioned in the UG with respect to a care-about when looking real-time on the DSP (if you don't follow that, there will be the kind of crash that you see). If you are using classic ROV, it will only work in non real-time i.e you have to stop the code to see it. If you use new ROV, you can see logs in real-time.
