DCA connection issues

Hi I am getting a timeout error similar to a previous posted issue:

When I try and ping the DCA:

Everything else seems to work fine, I am wondering if perhaps it has to do with the hardware setup of the DCA? Below are some images of my DCA setup, can you let me know if they are correct:

it is connected to the AWR1843, is this the correct setup for this radar:

Thank you in advance

Can you check if the DCA is powered on and working correctly? You should be able to ping the DCA if you've set things up correctly. No additional software or configuration should be required for you to ping. You might want to try following TI's documentation and testing out your hardware with mmWave studio first.

Hi @moodoki, thank you for your response. I have tested the device with mmWave studio and it works fine. Since the original post I have commented out I have located the code that is causing the error:

self.dca_socket.sendto(self.dca_cmd['READ_FPGA_VERSION_CMD_CODE'], self.dca_cmd_addr)
self.collect_response()

(from mmWave_class_noQt.py)

I have commented out these lines of code and the remaining script runs until I get timeout errors after LVDS Stream:/>sensorStart is posted. When this occurs I also get a red LED light occur on the LVDS_PATH_ERR. When looking at the documentation it says:

Any ideas what could be causing this?

Thank you

The lines you commented out are part of the commands sent to the DCA board to configure it for LVDS streaming. Please check these 2 things:

• Ping the DCA board, you should not get a timeout.
• have you flashed the 1843 board with the firmware in this repo? firmware/xwr14xx_lvds_stream.bin
