uclinux on de3

hi,

i am new for fpga, and now, i need to run uclinux on de3

i follow the wiki step by step, but unfortunately when i use my own my_nios2_fpga.h it doesn't work.

i think i do the wrong sopc configure, so anyone can help me and write something to show how to build the sopc.

thx a lot!

Hi

I just search for this solution as well just now.
Before this i have ported linux on the stratix II developement board.

I took the DE3_150_DDR2_1G_1RANK reference design from the de3 system design cd and try port uclinux on that system. First problem i encounter is that the nios2-terminal hang after this display on the terminal:

nios2-terminal: connected to hardware target using JTAG UART on cable
nios2-terminal: "USB-Blaster [USB 4-1.2]", device 1, instance 0
nios2-terminal: (Use the IDE stop button or Ctrl-C to terminate)

Then i checked the system design again and found that the cpu reset vector and Exception vector are on onchip_mem

Then I disable the onchip_mem and connect the cpu instruction master and data master to the altmemddr which is the high performance DDR2 SDRAM. Then i reconfigure the cpu reset vector and exception vector to altmemddr, regenerate and recompile the design.

After all the configuration, the uClinux amazingly boots up. :D

but i do not know how to do,
so, can you give me some advice?
