IWR1843: EDMA semaphore is not being released during HWA-only demo

Part Number: IWR1843

Hi,

I'm currently in the process of porting the xwr68xx HWA-only demo project to the 1843 platform. I've modified the project configuration to point to the relevant 18xx libs, changed the target device platform to IWR1843, etc. 

I can build the demo and it will boot fine. But when I try to start the sensor (via the mmWaveDemo Visualizer), the code gets stuck waiting for the edmaDoneSemaHandle semaphore in DPU_RangeProcHWA_process() in rangeprochwa.c (line 2284).

This seems to be because the EDMA transaction never completes.

Any suggestions on where to look to narrow down the issue? I'm suspecting it is a difference in EDMA configuration between 68xx and 1843 but haven't been able to identify it.

Thanks
