KW45B41Z-EVK BLE examples fail with NBU/rpmsg assertion while other examples work normally

[JMT37]

Hi,

I am using the KW45B41Z-EVK with MCUXpresso IDE.

The following examples run successfully:

- lpuart_polling

- freertos_hello

- flexcan_loopback_transfer

- connectivity_test_bm

However, BLE examples such as:

- wireless_uart_bm

- beacon_bm

fail during startup and stop at an NBU/rpmsg-related assertion before BLE advertising starts.

I also tried using SDK 26.09, but I am having difficulties importing some example projects into MCUXpresso IDE.

My questions are:

1. Are there any required NBU firmware images that must be programmed before running BLE examples?

2. Is there any additional setup required for BLE examples on the KW45B41Z-EVK?

3. Are there any known issues with SDK 26.09 example import in MCUXpresso IDE?

Any guidance would be greatly appreciated.

Thank you.
