Unsupported Pin GPIO error with SDK 2.6.0

[kaushalyasat]

Hi,

We have developed our code against SDK 2.3.0 and I wanted to try to upgrade the SDK to 2.6.0. I had to remove CONFIG_OPENTHREAD_CHILD_SUPERVISION from my prj.conf, but after that the project was build. But when I flashed the new hex, it seems just hanged. There are no other code changes.

I tried debugging from the start to see where this happens. It occurs from the call to dk_leds_init (). 

I can trace the execution path down to 

static inline int z_impl_gpio_pin_configure(const struct device *port,

                        gpio_pin_t pin,

                        gpio_flags_t flags)

in gpio.h.

The error occurs in the line 1001.

__ASSERT((cfg->port_pin_mask & (gpio_port_pins_t)BIT(pin)) != 0U, "Unsupported pin");

There are no changes to the device tree. 

This is what I have in leds section of my device tree overlay.

	};

What could be going wrong here?
