Care to try setting the wlcore interrupt in the dts to IRQ_TYPE_LEVEL_HIGH and see if that helps? Also please check the interrupt line related pinctrl pull settings, if there's an external pull resistor the internal pull should be disabled for the interrupt line. > I also tried other changes in the device tree, kernel command line arguments > and kernel configuration, but I can't see any pattern in the result. > Whatever I try the initialization very often still fails with errors as > before.

Not sure about that though, I guess we have to wait and see. Regards, Tony
