Hi,

Did you make any change in the configuration or in the code?

Here what I see that processing of data is not done within given frame time and DSP goes into ASSERT.

Either revert those changes (in code/configuration) or increase the frame/chirp timing.

Regards,

Jitendra

Thanks. Yes, we modified the code for CAN transmission. Can you please tell how to increase the frame/chirp timing?

If you are using mmw demo (OOB) then frame periodicity is being set via CLI command (in *.cfg file), if using application from TI-Rex then search for 'frameCfg' to get the configuration parameters.

C:\ti\mmwave_sdk_03_05_00_04\packages\ti\demo\xwr18xx\mmw\profiles\

'frameCfg 0 2 32 0 100 1 0' (change marked 100msec to higher number).

description of all the configuration parameters are explained in the mmwave SDK user guide

Regards,

Jitendra

Thanks, I changed

#define SUBFRAME_MRR_PERIODICITY_VAL (6000000U) // 30ms

#define SUBFRAME_MRR_PERIODICITY_VAL (12000000U) // 60ms

Do you still face issue after increasing the frame periodicity??

Hi Jitendra, issue is fixed after increasing the frame periodicity. Thanks
