AWR1243： mmwavelink_example timeout

Part Number: AWR1243
Other Parts Discussed in Thread: DCA1000EVM,

Hi,

When I run the program, I get the following information.

And I found that HOSTINTR Line is high.

Refer to chapter 3.2.3 in <mmWave Radar Interface Control Document>, Can this phenomenon be understood as the mmWave Device Raise IRQ?

So what could be the cause of the program's failure?

Thanks!

    Hi Zane,

    I assume you have connected AWR1243BOOST with DevPack or DCA1000EVM and set only one SOP jumper (SOP-0) to make device functional mode.

    Could you share trace.txt here which is generated from this application, this file store all the SPI data in it. It will help us to look at the application flow and find the cause of this issue.

    Regards,

    Hi,

    I'm sorry I forgot to tell you about the running environment.

    Hardware Environment:  AWR1243BOOST ans DCA1000EVM

    Software Environment: Visual Studio 2013

    And I've set only one SOP jumper (SOP-0) to make device functional mode.

    There is only one sentence in trace.txt : 

    [18:48:44:040][VER]mmWaveLink Studio Version: 1.1.0.0.28.3.18.

    By the way, I can use the equipment normally by using mmWave Studio 02.01.00.00, when set SOP-0 and SOP-1 jumper.

    Thanks!

    Hi Zane,

    As per trace.txt it didn't get the HostIRQ interrupt. I'm not sure the reason why it doesn't here but work with Studio in SOP2 mode (development).

    Did you try mmWav Studio with only SOP-0 jumper (functional mode)?

    Few other experiment towards this -> after running the example (while it is waiting for poweron async event), try resetting the device manually by pressing SW2 switch.

    Regards,

    Thank you for providing me with ideas.

    I will monitor the level change of the IRQ to check why there is no interruption.

    Thank you very much.
