Hi Gai,

Have you already clicked on the load button before for BSS and MSS before SPI connect?

Hi Gai,

I can see a red light from your DCA board. Can you power cycle the DCA board and check again, if the connection is correct?

Hi Gai,

Are you able to see FTDI ports in device drivers?

yes，it is no problem in device drivers.

I wonder if rewriting the firmware will solve this problem? But I don't see AWR2944's automatic firmware writing in uniflash. How Do I want to write the default firmware?

Hi Gai,

Can you try with some another EVM and see if you are having same issue or not?

when reset the device and connect the RS232 and load the firmware your screen should be like this.
