Hi,

Thank you for quick response, I changed the status disabled to okay in dts, pcie is detecting now, but uart lines are not working on M.2 card and Bluetooth reset(GPIO3_5-> gpio101) its always high. Please share the inputs on M.2 uart issue.

Thanks

The uart and reset gpio should be controlled by driver, like NXP M.2 BT driver.
