Hi NXP,
We have an issue with the IW610 DRIVER working with Ambarella processor-based SBC [Ambarella CV75 EVK]. The IW610 HW is the Murata 2KL Module which is connected to the host over USB interface.
[DEVICE SETUP]:
The setup is that the customer (VVDN) is using a 5G/LTE module + 2KL Module on the same host through a USB HUB -USB4216 from Microchip.
[ISSUE]: At boot up the 2KL MODULE (IW610) is detected and enumerated correctly, but the 5G/LTE module detection is failing. If the device is rebooted with the 5G/LTE modules only connected to the system it enumerates correctly.
The issue is seen whenever the other USB devices are getting enumerated post the enumeration of the 2KL module. All devices enumerated before the 2KL enumeration work correctly.
Attached is the customer console logs and WiFi/BT driver Debug logs.
Looking forward to your support.
Thanks,
Pankaj Sant
Hello @pankaj
Sure let me check your logs.

Hi @shaun_wu ,
The issue is not related to external radio co existence but with the device enumeration over USB.
Can you support to investigate the enumeration issue with the provided logs. incase if you need additional logs kindly let us know.
Hello @pankaj
For multiple radio chip, we provide external coexistence interface to control radio traffic. You may follow the guide to connect and configure coexistence:
