For this board you can download the image for the gdb stubs via a JTAG cable using a programmer running on a PC. I was using Linux for developemt and a laptop for downloading the image file for gdb stubs onto the board. The laptop was not networked so i had to move the image file on a floppy. What proved to be the problem was the floppy disk itself. If you download a corrupted image file nothing will work. Also try to use some ready made binary from the eCos site to test if this is working properly on the board. I am not familiar with the board your are working with but can you download an image using the serial port ? So make sure the image is right an it is downloaded right. good luck, vlassis
