Hello Everyone,

On our imx7d board, we are using murata 1mw wifi+bluetooth module. I observed that Bluetooth crashes after downloading patch files.   

log is here:

The highlighted part shows the reason for the crash in the Bluetooth stack, it is getting packet type unknown, which causes it to fail.

If there is no patch file, it works fine. But I need the patch file to work so that I get updated bluetooth firmware.

Can somebody please help, how to resolve this.

Thanks,

Asma
