Hello All,
We are working on the EP8260M1.3 Embedded planet board.
We have erased the planet core bootloader image from the board 
and downloaded our U-boot image for ep8260.
We now want to restore the planet core bootloader image back.
We have tried the following steps:
1.We tried burning the image with Code Warrior.We were unsuccessful in
getting the Planet Core boot loader Command prompt.
2. We decided to try burning the Planet core bootloader using the Flash
burner Application bundled along with the board. Embedded Planet provides
both these images in srec format (PCL82xx106.ep, PCB82xx105.ep). We
converted both these Srec images to Bin using MOT2BIN utility. We placed the
Planet core bootloader Bin image at 0x00100000 and the Flash burner Bin
image at 0x00200000.We then gave the command "go 0x00200000" to launch the
Flash burner. But we get the message:

## Starting application at 0x00200000 ...
