AWR2243: Advanced frame configuration in cascade mode showing invalid data between frames in captures

Karthik Choutagunta

Part Number: AWR2243

Hello,

The following question is related to programming an advanced frame config in cascade mode on the AWR2243 radar devices.

My advanced frame has only 2 subframes (out of a maximum of 4). The first subframe has 12 chirps per loop, 64 loops per burst, 1 burst, and 1 burst loop. The second subframe has 1 chirp per loop, 64 loops per burst, 1 burst and 1 burst loop.

I am running LUA scripts using the shell in mmWave Studio, and calling ar1.AdvanceFrameConfig_mult() to setup the advanced frame. I believe this function programs appropriate values in AWR_ADVANCED_FRAME_CONF_SB (page 95 of Radar Inferface Control Document).

My question --
When I take captures and inspect the ADC data from master/slave .bin files, I get invalid (= +/- 7710) between consecutive frames, as shown below.

Any ideas what could be causing this? Please see the attached code I am using (.lua saved as a .txt because I am unable to upload lua files for some reason).

Sequence being followed

A. CONFIGURATION
1. Connecting to TDA
1. Configuring Master from SOP till Channel Config
2. Configuring Slave (i) sequentially from SOP till SPI Connect. i = 1, 2, 3
3. Configuring Slaves together from F/W download till Channel Config
4. Configuring all devices together from LDO Bypass till Frame Config

NOTE:
Update the following in the script accordingly before running
1. metaImage F/W path on line 32

The sensor configuration consists of 3 sections:
1) Profile Configuration (common to all 4 AWR devices)
2) Chirp Configuration (unique for each AWR device - mainly because TXs to use are
                        different for each chirp)
3) Frame Configuration (common to all 4 AWR devices, except for the trigger mode for the master)

Hi Karthik,

Could you confirm if default LUA script (in the Studio installation) works fine in terms of capture and plot?

Regards,

Jitendra

Hi Jitendra,

Yes, the default Cascade_Configuration_MIMO LUA script provided in the Studio installation works fine in terms of capture and plot. Please see the below ADC data -- we don't see any gaps between frames.

I've modified this default script to transmit advanced frames but I see gaps between frames, so I am not sure if I am missing any steps. For reference, this is the MIMO advanced frame scheme I am trying to achieve:

There are also a bunch of parameters in ar1.AdvanceFrameConfig_mult that I don't know what they mean. Typing "help ar1.AdvanceFrameConfig_mult" into the LUA shell does not provide much clarity. For example, what are "Clone SubFrames" and "Num Of Chirps in DataPacket" ?

Your help is greatly appreciated! Thank you.

Best,

Karthik

Hi Karthik,

Would it be possible to process your ADC data partially (whatever is valid) and see if one particular subframe is causing the issue? You can also check your data sizes per subframe and compare it with what is supposed to be. If a particular sequence of chirps is found to be problematic, you can try to debug the same by varying small parameters in that particular subframe and seeing what could've caused this. This will also validate your steps.

Regards,

Kaushik
