DCA1000EVM: Fpga connection issue (AWR1843BOOST)

Hi everyone,

I have troubles bringing up the DCA1000EVM ethernet capture example using the lua script together with the AWR1843BOOST EVM.

As far as I can tell I have followed all guides. I installed the current mmwave studio 2.01.01.00 and also see the serial devices. I can get as far as the SPI connect but run into timeouts when the script wants to connect to the FPGA. It can not even query the version, when I use the DCA1000 Gui-Util on the side manually to connect to the FPGA.

I run mmwave as recommended as admin and I also disabled WiFi, any company VPN and the Windows (Defender) firewall just to be sure.

Here the failing part fom the lua script.

17:46:24]  [RadarAPI]: ar1.CaptureCardConfig_EthInit("192.168.33.30", "192.168.33.180", "c:22:38:4e:5a:c", 4096, 4098)

With Wireshark I can see that at least the DVM respons as I see some packets originating from 192.168.33.180 .Everything else seems to be working fine (AWR1843 is in SPI-Mode and SOP0 ON, SOP1, ON, SOP2 OFF) Also I tested powering it from a two supplies (switched DCA1000 to DC_JACK supply)  and one supply connected to the radar board only (RADAR 5V IN), but it does not make any difference. I also tried HW_CONFIG instead of SW_CONFIG, but does not make any difference.

Anything that I am missing? Have I interpreted some setting wrong?

Best regards,

Markus
