AWR1843BOOST: Out of the box demo issue. Can't seem to understand why

Vladimir Marchand

Part Number: AWR1843BOOST

Hello,

I just started using the EVM AWR1843BOOST and naturally went for the Out of box Demo.

I managed to do pretty much everything by following the steps, but for the last one I get an issue that I don't understand.

In the mmWave Demo Visualizer, when i do "send config to mmWave device", it seems to go well until the console shows :

Does anyone knows about this issue ? Is it comming from the sensor itslef or is it a software issue ?

Best regards.

Hi Vladimir,

Can you tell me which version of SDK you are using?

I'm using the 3.6.0 for the xWR18xx
Strangely after installing the demo Visualizer locally I managed to launch the sensor and get some data.

But after restarting the Visualizer locally I met the same issue once again...

By the way I went and tried using the CCS debbuging mode for the demon and got the following result :

Maybe it will help ! I'll wait for Animesh

Ok, I managed to make it work by following the advice from an old post I found.

I changed the LdoBypassCfg like so :

But i'm not really sure if this is done right...

I'll wait for you confirmation!

Hi Vladimir,

Go to mmwave folder/mmave_link.c > MMWave_startLink function > runTimeCalib.oneTimeCalibEnMask and comment the 3rd line i.e TX power calibration in the code and rebuild the library and demo and test the application.
