TIDEP-01012: TIDEP 01012 MMWAVCAS-DSP-EVM frame dropping issue

Part Number: TIDEP-01012
Other Parts Discussed in Thread: AWR2243,

Hello,

I’m experiencing frame dropping while capturing data with the eval board TIDEP 01012 (cascade AWR2243).

I made different sessions, saving data on SSD. When downloaded the data (_data.bin and _idx.bin) and opened I could experience data missing.

The frames timestamps contained in the ancillary “*_idx.bin” binary files point out recurring dropping of consecutive frames (gaps up to 300ms have been observed) which tend to occur with a periodicity of about 6 seconds (more frequently the interval between consecutive data gaps is between 5.5s and 6.5s or a multiple of it, but sometimes two gaps occur at short time distance in the same 6s interval).

As far as I have noticed this phenomena affects equally two different TIDEP-01012 boards that I have, and the frequency of frame droppings appears to be constant while varying frame interval from 5ms to 20ms and total data rate from 36MBps to 4.5MBps.

Is there any internal calibration or "pause" of TIDEP-01012 board that I'm missing or out of my control? 

Thank you,

Federico

  • Hi,

    Frame dropping should not happen, especially at lower data rate.

    Our support team did not receive similar feedback from other customers. Most frame dropping has been noticed with high data rates

    Unfortunately we don't have a good explanation for this behavior

    thank you
