IWR6843ISK : Project initial settings

Hi,

This lab requires some minor porting and retesting to run on an IWR/AWR6843. And the chirp profiles need to reflect the change in frequency.  We have completed these updates and will be pushed to the Automotive Toolbox in the next few weeks.

Dear Dave,

I changed the AWR1642 part to IWR6843 by referring to Migrating to xWR68xx and xWR18xx Millimeter Wave(Rev.B).

When debugging, the following error occurs.

[C674X_0] Heap L1 : size 14336 (0x3800), free 12288 (0x3000)
Heap L2 : size 49152 (0xc000), free 38392 (0x95f8)

xdc.runtime.Error.raise: terminating execution

I want to know where the problem is.

Thank you.

>I want to know where the problem is.

So you would start by looking at line 1072 of mss_main.c - the code is pointing you to the assert.  Sometimes this is enough information you give you the hint you need.  You can also set a breakpoint on this line and see the call stack to find where it came from.

The main VOD demo (lab0003) already supports 1642, 1843 and 6843. You can browse this source looking for SOC_XWR68XX, to see where the code differs for 6843.  You should also compare this code to your port as there are SDK initialization differences as well (I imagine this is what is causing the assert).

WRT your config, these also need to change for 6843 (ISK):

channelCfg 15 5 0

chirpCfg 0 0 0 0 0 0 0 1
chirpCfg 1 1 0 0 0 0 0 4

I will close your other thread on this topic.

Dear Dave,

Thank you for answer.

No error code in debugging when you proceed as you said. The contents are as follows.

[C674X_0] Debug: MMWDemoDSS mmWave Control Initialization succeeded
[Cortex_R4_0] **********************************************
Debug: Launching the Vital-Signs Monitoring Demo
**********************************************
Debug: VitalSignsDemoMSS Launched the Initialization Task
Debug: VitalSignsDemoMSS mmWave Control Initialization was successful
Debug: CLI is operational
[C674X_0] Debug: MMWDemoDSS Data Path init succeeded
Debug: MMWDemoDSS initTask exit
[Cortex_R4_0] Sensor has been stopped
Debug: MMWDemoMSS Received CLI sensorStart Event

However, when I run the Matlab program, an error occurs.

In debugging, there are no confirmed errors, but which part do you think is wrong?

The error is as follows.

Thank you,

There's one more change your config needs.  For xWR6843, the lowPower command should be: lowPower 0 0.

We haven't pushed that change to the Resource Explorer yet. Beyond that, you might try stepping through the command send process in Matlab and see what the response is (if any) to sensorStart. It looks like everything to that point was confirmed.
