AWR2243: mmw_example application does not work

Part Number: AWR2243
Other Parts Discussed in Thread: DCA1000EVM,

I tried to execute the mmw_example application from mmwave_dfp_02_01_05_03/ti/example/mmWaveLink_Cascade_Example but it fails.

I looked into mmw_example.c and it seems that the devices get powered on before the firmware download. Is this intentionally? Because if I try the same in mmWaveStudio it fails with error -8.

Best regards

    Hi,

    It is expected to have differences between the init in mmwave studio and mmwavelink examples.

    What is the error you see?

    thank you

    Hello Freddo,

    The application makes device power on or Reset and then only it downloads the firmware over SPI.

    If it doesn't work as expected then make sure of these points:

    1. Connect DevPack or DCA1000EVM with AWR2243BOOST EVM. As SPI and reset lines are available over these external boards. DevPack you need to stack with AWR2243BOOST and if have DCA1000EVM then you need to connect Blue MIPI connector to AWR2243BOOST.

    2. Do you see RESET (red) LED blink as soon as you start the application? it is indication of reset is being driven by the application successfully.

    3. If not then try to press NRST button first then start the application exe.

    4. On another side with the mmwaveStudio, looks like you are not following the correct steps to work with it. Please follow the mmWave Studio User guide to use this GUI with the board.

     

    Regards,

    JG

    Hello Jitendra,

    I do not have the DCA1000EVM and AWR2243BOOST but the MMWCAS and MMWDSP EVMs. Thats what the Cascade Examples are for or am I wrong?

    Hello Freddo,

    I didn't notice that you are using cascade setup.

    Could you try the same experiment with mmWave Studio and see if you are seeing same behaviour? Please follow the instruction in the mmwave_studio_cascade_user_guide.pdf document (in mmwave Studio installation docs folder) for the right steps to use mmWave Studio.

    And yes AWR device powered on first, to get firmware over SPI then it switch to updated firmware.

    mmWave Studio is working fine - no problems there.
