Hello,

I am trying to use the IWR6843AOP with the DCA1000 evm. I am having trouble with the spi connect step. The output from mmwave studio, the connections, and the gui can be seen below. Could you please help me fix the issue with the connection.

Hello,

Your AOP and DCA1000 switches seem correct, and I am going to assume there is also a USB cable connected from the AOP to the computer in addition.

Unfortunately MSS Power Up async event was not received is an error that can be caused by several different issues, but the problem is due to connection issues between DCA1000 and computer with likely no relation to the mmWave sensor. I would attempt possible changes involving the Ethernet connection, such as checking your static IP settings and disabling your firewall. I personally ran into this exact error once due to a bad/incompatible Ethernet cable so try changing the cable as well.

Ensure you follow the steps in the guide below in the exact order they are shown in with no steps skipped.
