AWRL1432BOOST: AWRL1432boost+DCA1000: When i use another chirp.lua, DCA can't save adc data

Hi,

The reason for this is that there is not sufficient time to send the data through the Ethernet Interface.

You will need to reduce the number of chirps

thank you

Cesar

what is the Maximum value of chirps? If i want to capture adc data with 256numChirpsPerFrame*256numAdcSamples config, What should I do?
Thanks

For two lua script, chirp numbers is equal, 2num_chirp_per_burst*128num_burst_per_frame

What application are you interested in?

Could you try with lower number of chirps, for example 192 and 224?

Thank you

Cesar

I find the reason is hpf_sel parameter. When hpf_sel =3, it can't record adc data success, change hpf_sel to 1, it works. So what's the difference?

Hi,

This is the DFE high pass filter corner frequency. In most cases hpf_sel = 1

local hpf_sel = 1 -- HPF corner frequency 0: 175KHz; 1: 350KHz; 2:700KHz; 3: 1400KHz

Is there any reason that you selected hpf_sel = 3?

Thank you

Cesar

In mmwave demo profile.cfg, ChirpRxHpfSel is set to 3.
profile.cfg file located in C:\ti\MMWAVE_L_SDK_05_04_00_01\examples\mmw_demo\mmwave_demo\profiles\xwrL14xx-evm

Hi,

For this demo we should use hpf_sel=1.

Regarding capturing the raw data, let us reproduce the behavior

We will get back to you next week

thank you

Cesar

Looking forward to your reply.

Hi Peng, 

Can you check both of your profiles using the sensing estimator and run them with the OOB demo to make sure both are correct before using them for raw data capture?

Can you also provide me with the 2 lua scripts you are using?

Please refer to the screenshot above

Hello, Is there any new progress?

Hi Peng. I need access to both of the Lua scripts in order to replicate your issue. The 2 screenshots are not enough. Thankyou.
