hi:

i use the quartus 5.0 + sp1, nios2 5.0 now.

do i must update the tool to quartus 5.1 + sp2, nios2 5.1 + sp1 if i want to use

the nios2 linux tool chains?

because if update the quartus tool maybe affect the fpga design previously,it will

spend much time to redressal the use logic.

please give me some advice ?thanks a lot!

I would recommand you move to the latest tools. start with mininal logic, with only sdram cfi flash, uart and timer. only after you have successful boot, then add more user logic step by step.

after you have all the logic, you can use quartusII&#39;s "design space explore" to improve speed/area .
