Dear @somashekars16k ,

See below, please!

(1) For LAN8840 integration to i.MX8MM & I.MX8MN

Please create a ticket for the question! TIC MPU team will support you.

OR

Follow my suggestions below.

LAN8840 is Gigabit Ethernet Transceiver (PHY) , whose porting will be very similar to default phy(AR8031), so you only need to tune corresponding node in device tree (should be sub-node of fec)

(2) For aw-cm276nf

If you use i.MX8MN,  select aw-cm276nf's SDIO for WiFi & UART for Bluetooth. Because i.MX8MN doesn't support PCIe interface.

If you use i.MX8MN, recommend you select aw-cm276nf's PCIe for WiFi & UART for Bluetooth.

The aw-cm276nf module supports interface options .

In i.MX8MN/IMX8MM default bsp, aw-cm276nf driver has been supported. you don't need to do any operations for it in Yocto.

Thanks!
