After starting DMIC recording using the shell command: record_dmic en
The DSP reports a component setup failure, preventing the recording pipeline from functioning correctly.

Expected Behavior
After executing:
record_dmic en
The DMIC recording pipeline should initialise successfully, allowing audio capture and VIT wake-word detection without any component setup errors.
Actual Behavior
The DSP reports:
[DSP Record] comp_setup failure: 4294967294
followed by an IPC response with:
error: 4294967295
As a result, the recording pipeline does not function as expected.
Request
Could you please help identify the following?
- What causes the comp_setup failure, 4294967294, in the default xaf_record example?
- Does this indicate a missing DSP component, codec configuration issue, or another initialisation problem?
- Is there any known issue or patch for the xaf_record example in SDK 26.06.00?
- Are any additional configuration steps required before using the record_dmic command?
Any guidance on debugging this issue would be appreciated.
Please find the above reply.
Hi @suhas1503 ,
Could you please provide some information about the IDE you're using? Is it MCUXpresso IDE or VS Code?
I tried to reproduce the issue in MCUXpresso IDE, but it ran fine.
I didn't find anything related to “[DSP VIT]” in your log information. I suspect this might be due to missing content in your local project rather than a software bug.
Best regards,
Gavin
I was able to reproduce the issue using the same package.
I’ll conduct an internal investigation to see if there are any discrepancies. This may take some time. In the meantime, I recommend that you continue development based on the MCUXpresso IDE project to save the time.
Once the issues with the SDK package based on the ARM GCC toolchain have been resolved, you can port your project over.
We have downloaded the sdk from the below link; also attaching the snap; we downloaded sdk version 26.06.00
