How to porting u-boot to my own board?

Hi LiangYi,

Great!

> I download the u-boot to my flash at 0x0 using Flash-Programmer

How did you create the flash file? Typically, you should do the following:

$ elf2flash --base=0x0 --end=0x7fffffff --input=u-boot --outfile=u-boot.flash --flash=<Uxx>

$ nios2-flash-programmer --base=0x0 --input=u-boot.flash --sof=<xxx.sof>

> Shell, run nios2-terminal. Nothing happen.

When you run out of sdram, do you use the jtag uart ... and did you see the command prompt?

If everything works with download/go to sdram, you most likely have a problem with the u-boot

image stored in flash (either the flash file is incorrect ... or flash memory is not correct).
