This incomplete paragraph makes it impossible to understand how to implement the OTAP Bootloader.

I also referenced this article

Reprogramming a KW36 device using the OTAP Client Software 

My interpretation of the above:
This bootloader can update the application of B board from A board via OTA

Question1:
   Suppose, I want to update B board from A board via OTA
   How to implement the steps of this "OTAP bootloader" function?
   For example,
          What software need install on A board ?
          What software need install on B board ?

 Maybe he only supports OTA update from Phone to FRDM-KW36 board ?

Question2:

   Which one is right?bootloader_otap_frdmkw36.bin = "bootloader_otap"  or  bootloader_otap_frdmkw36.bin = "otas"

Hello,

I would strongly recommend you to check the Bluetooth Low Energy Demo Applications User Guide where there is a brief explanation on how to deploy the examples in the way you desire. You can find the pdf file in the documentation of the SDK.

You will need a client and a server to deploy the example you want.That is the reason why you have different OTA examples.  In the example otax.. the "s" at the end stands for server and the "c" stands for client.

The board that will be updated needs an special boot loader in order to be upgraded via OTA, that is why you need the other project. You need to flash board B with the OTAP Bootloader and the OTAP Client and the board A with the OTAP Server.
