EK-TM4C129EXL: Load blinky.bin via (UART) Bootloader

Part Number: EK-TM4C129EXL

Hello,
I have Code Composer 6.1.2 installed. I'm just trying to load the sample project blinky via the (Uart) bootloader. Unfortunately, the blinky program does not start.

I removed the jumpers BoosterPack, OTG, CAN1, CAN2, UART1 and UART2. Only the jumper at ICMP is set. At the pins PA0 and PA1 I have a UART converter connected, which is connected to my PC.

Then I load the project boot_serial via JTAG interface in the Microcontoller. Then I open LM Flash Programmer.

I load the blinky.bin via the Uart botloader into the TM4C129. My Uart-USB Converter lights up and below is Programming. There is no error, but after the program has been loaded, it does not start. What can this be? Please help me

    The example "blinky" (C:\ti\TivaWare_C_Series-2.1.4.178\examples\boards\ek-tm4c129exl\blinky) is designed to load at address 0, the same address as the bootloader. The bootloader loads blinky.bin at address 0x4000. Look at the example project boot_demo1. In the link command file, boot_demo1_ccs.cmd, you see that the flash memory starts at 0x4000 instead of 0. Also the .intvecs section is bound to address 0x4000 instead of zero.
