AWR1243: mmwavelink porting

Laszlo Techy

Part Number: AWR1243

Hello,

I am working with the AWR1243 chip, and I am having some difficulty with the porting of the mmwavelink driver.

I think I have a basic understanding of what needs to be done (steps 1 through 9 in the porting guide). I am done with steps one and two, and implemented the spi callback functions. I understand that SPI communication and the interrupt handling are intertwined (due to Host IRQ), but I find the porting guide too lean on documentation on what needs to be done here. An example code snippet would really help.

I browsed through forum posts trying to find anything related, and came across this thread:

https://e2e.ti.com/support/sensors/f/1023/t/799855

However, I am unable to access the example code rl_nonos.c, etc... that are provided in the comments by Jitendra. I am wondering if I could obtain this code? Or something similar that would help me understand the interrupt framework a little better.

Thank you for the help in advance.

Best,

Laszlo

Hi Laszlo,

We need some time to check about access to the code you refer to and will get back to you on Friday.

Hi Laszlo,

rl_nonos.c reference code is available in the same thread.

https://e2e.ti.com/support/sensors/f/1023/p/799855/2985875#2985875

And in the same thread all the application reference also available, you need to stitch all the points here with the mmwavelink_example and port it on your platform.

Please let us know if you have any other query.

Regards,

Jitendra

Hi Jitendra,

Thank you for getting back to me. I haven't been able to access the code that is referenced in the thread above, because I have difficulty with Code Composer Studio. That is a little bit aside from this thread, so I think I will start a new topic about that.

I will sketch up a few more specific questions, and get back to you.

Best,

Laszlo

Hi Laszlo,

In the recent mmWave DFP we have provided a reference application with no OS (mmwavelink_example_nonos).

http://software-dl.ti.com/ra-processors/esd/MMWAVE-DFP/latest/index_FDS.html

This application is based on Visual Studio not CCS

Please refer this application.

Regards,

Jitendra

Hi Jitendra,

Thank you for bringing this to my attention. I have looked at the code, and would like to build it. But I get some link errors.

mmwlstudio.lib(rls_studio.obj) : error LNK2019: unresolved external symbol __imp__sprintf referenced in function _rlsGetTimeStamp

I think this is related to the library being created with a different version of Visual Studio than what I am working with (VS 2017). I did upgrade to my VS Platform (Properties -> General -> Platform Toolset: v141, but to no avail. I spent a few hours searching, and I am almost at a point where it would seem easier to create a new project from scratch and add all the dependencies manually. But I wonder if you have any insight. Maybe it is a simple project setting fix that I haven't figured out yet.

Best,

Laszlo

Hi Laszlo,

I'm not sure of the exact solution but you need to search this on MSDN forum.

Meanwhile you can try including 'legacy_stdio_definitions.lib' to linker->input of project properties.
