How to create two task with different task priority?

[Cooper]

SDK version: 14.2.0

I use "ble_app_hrs_freertos" as code base and modify it to create a "ble_app_template_freertos" project.

"softdevice_task" is already in this project (uxPriority = 2).

I can use "xTaskCreate" to create a new task "task1" and the uxPriority is 1, and work normally.

And I modify "softdevice_task" uxPriority to 5, and "task1" uxPriority is 1 it works normally too.

But when I add a new task "task2" and the uxPriority set to 2, the system not work.

And I found when this project only have "softdevice_task"(uxPriority = 5) and "task1"(uxPriority = 2), it doesn't work too.

How to solve this issue?

The code config below doesn't work.
