DE2 NIOS HELLO (Use on-chip Memory)

rich

此範例顯示如何利用DE2 有限的on-chip memory, 來建立NIOS Project.

========================================
NIOS Project (System Library Properties) 開啟:
NIOSII-IDE-->File-->Switch Workspace...
輸入路徑...\DE2_NIOS_HELLO\software

在哪？看不到啊？

可能檔案太大了, 上傳失敗. 明天我再看看解決方式.

應該可以下載了, 請試看看. 這個project 是用quartus 9.0 建的.

are you running on "hello world" or other application, i am trying to run "hello microC-OS II" with a 18kb on chip memory, i have changed "System Library Properties", ticked all the boxes to redudce the memory needed such as "small C libary" etc. also disable the OS codes in "RTOS" library settings, dispite that there are error of disabled too much of the OS codes, i am still short for memory to run the "hello microC-OS II" ,  mentioning that on the Micrium website saying that the microC-OS II can run on a 2kb memory, just asking if anyone or the master knows any way to configure this on NIOS 2 or using Quartus 8.0.
i am using a cyclone 2 ep2c20 by the way.
if anyone can give any advice, thank you very much

18K好像不够吧....

“最少2K”，是指的最小核心代码吧，默认的情况好像不只2K吧

thanks for huguang's reply to me.
ya on default, that is if you don't configure any of its system library, it takes about 80kb of ram. i can change some of its system library, the best i could get by configuring the system library is taking totally about 30 kb.
the problem can be solve by using a sram but which i don't have on my microcontroller.

and still trying to figure out how to get some kind of  "最小核心代码" by quartus or nios, the good thing is i am only running a small application therefore not a lot of the RTOS codes that i will be using.
very frustrating
