IWRL6432BOOST: MMWave_init() function hangs

Tool/software:

Hello,

CCS: Version: 12.7.1.00001

SDK MMWAVE_L_SDK_05_04_00_01

IWRL6432BOOST PROC117 Rev.B

I'm just working on building an application from scratch using the various APIs available in the SDK. I'm following the mmWave API documentation and stuck on the first step, initialising the module!

Debugging the code shows that it hangs at rl_mmWaveLinkInit(). The debugger stops at the line above this in mmwave_link_xWRLx4xx.c, pressing Step In doesn't do anything, it won't progress any further. No errors are reported back, the application just endlessly hangs.

Hi Peter,

Are you following the steps in the debug guide? (Resetting the board every time)

Best,

Nate

Hi Nathan,

Yes I believe I am following the steps in the debug guide. I am also building the application as "Release" as suggested in the FAQ.

If I stop the application when it hangs, it ends in HwiP_hardFault_handler.

I am able to successfully build & run the mmwave_example provided in the SDK examples folder. I will try and spot the difference in the initialisation process..

Sounds good. Let us know if you have any more specific questions.

Best,
