Original question:

DCA1000EVM: Change Ethernet Address

DCA1000EVM: Changing Source IP address for DCA100EVM

Part Number: DCA1000EVM
Other Parts Discussed in Thread: AWR1243

Hello,

I am trying to change the source IP address of a DCA1000EVM connected to a AWR1243, we are using the LUA Shell that is integrated in the mmWaveStudio software and we have a few questions.

1) We are using the following set of commands: 

  1. connect to DCA1000 with mmwave studio GUI.
    1. ar1.SelectCaptureDevice("DCA1000")
    2. ar1.CaptureCardConfig_EthInit("192.168.33.30", "192.168.33.180", "12:34:56:78:90:12", 4096, 4098)
  2. change address with EEPROM command
    1. ar1.ConfigureRFDCCard_EEPROM("desired IP string", "desired IP string", "12:34:56:78:90:12", 4096, 4098)
  3. close mmWave studio
  4. reset DCA1000
  5. change your system IP

However, we aren't able to successfully connect to the DCA1000 after changing the source ip address (A error message of 'Ethernet cable is disconnected')

2) Is there a script that we can use to configure the DCA1000EVM board without having to navigate through mmWaveStudio every time to configure a board?

    Hi,

    Can you toggle switch SW2.6 to the GND position and try again? This forces the DCA1000 to use the hardcoded IP address.

    You can then overwrite the address in the EEPROM again and toggle the switch back if needed.

    Please refer to Table 8 in the DCA1000 User Guide available here:

    Best Regards,
