IWRL6432: MMWAVE-SDK Debug build

Morgan Greenhill

Part Number: IWRL6432

Tool/software:

I am struggling to get any of the MMWave SDK examples or hand-written code to work properly on the IWRL6432-BOOST board.

When debugging the compiled assembly it appears the rl_mmWaveLinkInit function is branching off into the ROM where there are no valid instructions, ultimately triggering a hard-fault. Having an SDK built with -O3 compiler optimization means this is almost impossible to debug effectively.

There are some .bat files within the SDK that are for building with different configurations but none of them work, they are looking for a 'tools\cgtools' directory which does not exist.

I can build and debug other applications fine, so there is no issue with the board itself.

Could you please either provide me with a debug build of the SDK or a method to get these .bat files to work so I can build the SDK without any compiler optimization.

Hi Morgan,

https://dev.ti.com/tirex/explore/node?a=1AslXXD__2.10.00.04&node=A__AKZl2I1OiS5ssBNGpidsCQ__radar_toolbox__1AslXXD__2.10.00.04&r=1AslXXD__1.00.00.26&r=1AslXXD__1.00.01.07

Have you tried the steps above?

Best,

Nate

Hi Nate, yes I have tried that. I think the problem is deeper than the configuration of the board because I can debug and run applications without the SDK no problem. It is only when the SDK is introduced the problems start.

I am well versed in ARMv7-M assembly, so a non-optimised binary would be ideal to debug this properly.

Hi Morgan,

What SDK version are you using and what revision is your silicon?

I am using 'MMWAVE_L_SDK_05_05_00_02' and silicon revision ES2.0.

Hi Morgan,

Does the prebuilt binary run for you? Or just when you build it and flash the built image onto the device. We have prebuilt binaries ready in the SDK. Can you test those?

Best,

Nate

Yes, some of the pre-built examples run OK but they aren't really of much use because we can't debug them properly.

Ok so it sounds like the issue is with your local build. Can you confirm that the motion and presence pre-built image runs correctly, then see if your tooling matches the instructions in the user guide here for your build?
