@erwango will you be looking at this? If not, please reassign.

In counter_tear_down_instance, counter_set_top_value(dev, &top_cfg) is called with following top_cfg value:

	struct counter_top_cfg top_cfg = {
		.callback = NULL,
		.user_data = NULL,
		.flags = 0
	};

Then, it fails on error.

I don't think this call is matching description of counter_set_top_value contract in counter.h.
@nordic-krch as counter API owner, can you verify?
