TMS570LC4357: Hercules_Ethernet_Bootloader starts the app, but the app does not run properly.

Part Number: TMS570LC4357

Tool/software:

HI  : 

    I am using the TMS570LC4357 development board. Currently, I can successfully run the TMS570LC43x_rtiBlinky_BL_APP20020.bin using the Hercules_Ethernet_Bootloader. However, when I load my own created app, it does not run properly. 

    

I have verified my app program, and it can output correctly via UART with the following link.cmd: 

VECTORS (X) : origin=0x00000000 length=0x00000020
FLASH0 (RX) : origin=0x00000020 length=0x001FFFE0

FLASH1 (RX) : origin=0x00200000 length=0x00200000
STACKS (RW) : origin=0x08000000 length=0x00001500
RAM (RW) : origin=0x08001500 length=0x0007EB00

When using the Hercules_Ethernet_Bootloader to load and run the app, I modified the link.cmd as follows:

VECTORS (X) : origin=0x00020020 length=0x00000020
FLASH0 (RX) : origin=0x00020040 length=(0x001FFFE0-0x20040)

FLASH1 (RX) : origin=0x00200000 length=0x00200000
STACKS (RW) : origin=0x08000000 length=0x00001500
RAM (RW) : origin=0x08001500 length=0x0007EB00

tms570lc43x_bootloader_app.zip is the project I created.

My Questions:

1   Where can I find the project for TMS570LC43x_rtiBlinky_BL_APP20020.bin

2   What issues might there be with the project I created?

thanks.
