RW610: VIT v4.11.0 returns INVALID_DEVICE despite successful model initialization — hardware ID 0x00

Hello Team,
I am integrating Voice Intelligent Technology (VIT) into a custom board using an RW610 MCU. The model loads and all initialization APIs succeed, but VIT_Process() returns VIT_INVALID_DEVICE (11)

Could you confirm whether the VIT library below supports my RW610 silicon, or whether a different library release is required?

Item Configuration

MCU	NXP RW610 on a custom board
Audio codec	MAX98089
IDE	MCUXpresso IDE - 24.12.0
RTOS	FreeRTOS
Debug output	Semihosted printf
VIT package	release/24.12.00/CortexM33-RW61X
Library	libVIT_CM33_RW61X_v04_11_00.a
Library version reported at runtime	0x00040b00 — v4.11.0
VIT API version	0x00030400
Model version reported at runtime	0x00040b00 — v4.11.0
Configured device	VIT_RW610, numeric value 9
Operating mode	VIT_WAKEWORD_ENABLE

Model generation:
I generated a replacement English model using NXP’s online model-generation tool with these settings:

Device selected in the portal: RW612
Portal version: 24.12.00

I selected RW612 because I did not see an RW610 option in the portal.
The generated VIT_Model_en.h declares v4.11.0. Only wake-word recognition is currently enabled in the application.

The VIT initialization sequence is:
1. VIT_GetLibInfo()
2. VIT_SetModel()
3. VIT_GetModelInfo()
4. VIT_GetMemoryTable()
5. Assign aligned, statically allocated memory regions.
6. VIT_GetInstanceHandle()
7. VIT_ResetInstance()
8. VIT_SetControlParameters()
9. VIT_GetStatusParameters()
10. Start microphone capture and call VIT_Process().
All listed initialization calls succeed. Processing then returns error 11.

Device-check observation
Inspection of the linked library’s device-validation code indicates that, for device ID 9, it reads address 0x45001114, clears the lowest eight bits, and compares the result with 0x00007000.

Does libVIT_CM33_RW61X_v04_11_00.a support RW610 devices that return 0x00007102 at address 0x45001114?

Is the comparison against 0x00007000 a known compatibility limitation or issue in this release?
Which VIT library release and matching API headers should I use for this RW610?

Is a model generated with the portal’s RW612 selection supported on RW610, or is a separate RW610 model-generation option required?

Please advise on the supported library/model combination and any further diagnostics needed.
Thank you.
