AWR2944: advance frame profile in DDMA mode

DRF

Part Number: AWR2944

hello ，i‘m using AWR2944 ，in DDMA mode i want to design a two waveform alternately transmit method to extend velocity，by reading TI design deocument i found advance frame profile can support this method，but when i finish profile the advance frame and debug in CCS，i find in MmwDemo_configPhaseShifterChirps()，if variable “gMmwMssMCB.cfg.ctrlCfg.dfeDataOutputMode == MMWave_DFEDataOutputMode_ADVANCED_FRAME”，the program is going to run“

CLI_write("Advanced Subframe Config is not currently supported with the DDMA chain\n");

errCode = -1;

goto exit;

”，so i really want to know AWR2944 in DDMA mode can support advance frame config or not？ if can ，how can i modify to achieve this pattern？thanks！

Hi,

May I know which version of the mmwave SDK you are using?

I would suggest you to move on the latest mmWave MCU Plus SDK 4.4 which supports advanced frame config. in mmw demo (DDMA).

Hi，Jiten，can i ask you one more question？By reading SDK4.4 program ，i find the program in DSS also modify a lot，so my question is if i only modify the program refer to SDK 4.4 in MSS and use the DSS program refer to SDK04_02_00_03,can i correctly use the advance frame comfig in DDMA mode？In short i want to know in SDK04_02_00_03 ，it cannot support advanced frame config in DDMA mode whether related to DSS（or DPC，DPU）？thanks a lot！

I would suggest to use all the components from the latest SDK 4.4 to avoid any hassle. Else you have hit multiple unexpected issue when you use combination of component from different version of SDK.

Device HW supports advanced frame config, it is matter of SW which should support this feature.
