IWR6843: rlGetRfDieId API have different output on SDK3.5 and SDK3.4

Wesley He

Part Number: IWR6843

Hello team,

rlGetRfDieId() API have different output on SDK3.5 and SDK3.4. Can you please provide an official reply on this issue? what's the reason and why it happen?

During my test, the RSS version will impact this output.

Please see my test result and code below.

Wesley,

My apologies for the delay here, I have had to bounce between a couple of different parties here. I still have not received a solid response, but I will try to expedite things to get this wrapped up.

Best Regards,
Alec

Wesley,

Can we check the device in SOP2 mode on mmWaveStudio and issue the ar1.GetDieId() command in lua to get the DIE ID for the two RADARSS versions? This can help us determine if it's a potential issue with the RADARSS or the SDK function.

Best Regards,
Alec

Hi Alec,

Yes, you can try it, but I had tried connect to mmWave studio direct without loading any RSS firmware, then got the ID same as the RADARSS 6.3.2.6 version.

Thanks.

Wesley,

Noted, thanks for that datapoint. Let me know what you find when checking with Radarss 6.2.1.5 in mmWaveStudio

Best Regards,
Alec

HI Alec,

if you can provide the LUA for this test. i can try it in my side. i have no idea how to put get_die_ID function in Lua scrupts.

Thanks.

Wesley,

You should be able to run a lua script with that single line that I posted. Just be sure that you load the RadarSS image in mmwaveStudio before you run the lua script. The RadarSS image can be found in the SDK at {SDK_LOC}\firmware\radarss

Best Regards,
Alec
