Not working with IWR6843ISK

[valentinbarral]

Hi,

I've been trying to run the DCA1000 with the IWR6843ISK and this iwr_raw_rosnode but I can't get it to work. The steps I have followed are:

• Flash the firmware firmware/xwr68xx_lvds_stream.bin on the IWR6843.
• Use as configuration the firmware/lvds_stream_68xx.cfg file.
• I have created a new .launch file to use that configuration file.
• The 6843 switches are set in the DCA1000 mode (off, on, on, off, off, -).
• The ip on the pc is 192.168.33.30.

When I connect everything and launch the node, I see that the communication with the DCA1000 using the socket is correct, and it responds to the commands. Then the commands are sent by the serial port to the 6843, and the sending is also done correctly although no response is received (I don't know if the firmware is programmed to do it). From there, after a few seconds a timeout message appears continuously on the console, and then the LVDS_PATH_ERR_LED turns red on the DCA1000.

I think I have tried almost everything, the only thing I have not modified is the firmware xwr68xx_lvds_stream.bin. Has this fw ever been successfully tested?

Unfortunately, I do not have the IWR6843ISK to test the firmware with. Have you verified that your setup works with TI's mmWave studio? This ROS node is meant to communicate with the DCA1000 and the radar in a similar way that mmWave studio does.
