[Developer] Boot On Gumstix Hardware

[Carl van Schaik]

Hi Quanlong,

Do you have a gumstix board with a JTAG interface?
The image.boot file contains the image.elf file with only physical 
addresses in it for some loaders that tread the virtual address as 
physical. You should be able to use somthing like T32 or a bootloader 
like u-boot. Can you confirm that when using T32, the file is loaded 
correctly and the start address is correct. You can step through the 
code to see if the L4 init sequence is being executed.
If this is working, you may have another problem like wrong serial 
setup, different memory layout etc.
Let me know how you go on the first part before I talk more about boot 
issues.

regards,
Carl
