It was assumed from your screen shot that the Bootloadable (Application) starts from 0x1E00.
The Program Counter (pc) register indicates that CPU is running at 0x113A somewhere in the Bootloader.
Please show the Bootloader disassembly list at 0x113A to specify what is happen to the Bootloader.
Thank you for your advice for my Problem.
Actually, I do not have any experience about disassembly.
Could you give any material, how to get disassembly list?
Please ensure your Project's Build Settings is set to create the MAP file and LST file.
You can see MAP and LST files in the Results tab of the Workspace Explorer
For example, you can see where is the main() function on the Flash in the MAP file as follows.
In this case, main() function starts at 0x00000088. At first, please find what is located at the address 0x0000113A using the MAP file.
After that, refer the LST file to find the location of 0x0000113A. Please note that the addresses in the LST file are relative addresses from the starting address described in the MAP file.
In my case, the UART_PutString() function is called from 0x00000088+0x001e=0x000000a6
