CCS/AWR1642BOOST: AWR1642

Hello!

Recently I was debugging the configuration radar module of AWR1642. According to the observation of the spectrum analyzer, the chrip emitted is normal, and the number of chrip is the same as the set number. Chirp Available Interrup can also enter normally,

but the interrupt count is abnormal, so the number of chrip interrupts is less?

What causes this?

Hi,
What is the point of observation for chirp interrupt count which you see less in number?

Hi, DSP does not collect data in adcbuf according to chrip interrupt count?I used mem_capture engineering test in SDK, and the chrip interrupt number is the chrip value set, and the frame is set to 1

Hi, I am currently debugging my AWR1642 project, configuring BSS and adcbuf, and encountered this problem

Hi,

Have you tried running mmw demo application on the same device? To isolate if this error is due to software only. In mmw demo if any chirp interrupt is missed then application will go in assert to notify that some mismatch/error.

When you say that DSP doesn't collect same no. of chirp data, so did you process that the captured data from L3 and find out the no. of chirp in the data?

check the edma transfer completion interrupt as well compare to chirp interrupt counter.

Jitendra
