nothing out to uart,help me

Hi,Hippo

Thank you very much for your replay.

Today I use FS2 associated with the nios2 IDE to debug my image ,First I use the command "nios2-elf-objcopy -O srec vmlinux vmlinux.srec" in nios SDK shell to convert the elf to srec format,and doanload the srec image to my Cyclone board in FS2 console using the commands "load srec vmlinux.srec" and "go" then there are some message showing in the console as follow:

49> reset

User reset.

00800000 0x0001703a wrctl status, r0

50> set pc 0x0

0

51> load srec vmlinux.srec

52> go

Emulation started.

Software breakpoint.

00A00094 0x003da03a break

53> ls

./:

cfi_flash_0.flash generated_app.sh hello_world_0.elf hello_world_0.srec

makefile obj/ subdir.mk vmlinux.elf

vmlinux.srec

54> pc

0x00A00094

55>

The base address of my sdram is 0x0, I test my hello world application as above, and it work well. I support that the uclinux is also a application,but much bigger than our normal application.

I do not familiar with the nios instruction sets,so I do not know what to do now, should I study the nios instruction set ?

My e-mail is : scut_ak@163.com How can i touch you by e-mail and send my detailed info about my situation.

Thank you for your work done for us.
