[vinothkumars]

Hi All,

I unable to create the serial port (/dev/ttyLP1) for bluetooth.

Please find my configuration,

&lpuart1 { /* BT */
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_lpuart1>;
resets = <&modem_reset>;
status = "okay";

/* Enable bt driver for marvel uart8987 */
bluetooth {
compatible = "mrvl,88w8897";
status = "okay";
};
};

I unable to find the tty ,

/sys/devices/platform/bus@5a000000/5a070000.serial

Thank you @igorpadykov ,

I am working IMX8QM Custom platform with Yocto BSP (L5.10) version with Marvell chip for Bluetooth which is using UART interface.

Hi

The issue is resolved long time back. To connect with devices we should add the services like audio and file transfer (ex: pactl, obexftp)

Hi @vinothkumars ,

I hope you were able to add 8997 module with iMX8QM MEK board. Can you help me how you made Bluetooth working using 8997 pcie module?

Best regards,
