(原創) 如何自己用SOPC Builder建立一個能在DE2上跑μC/OS-II的Nios II系統? (IC Design) (DE2) (Quartus II) (Nios II) (SOPC Builder) (μC/OS-II)
Abstract
很多人跑DE2本身的範例，都可以上μC/OS-II這個作業系統，但只要自己用SOPC Builder建立的Nios II系統，就無法上μC/OS-II，本文示範如何用SOPC Builder手動打造一個在DE2上能跑uC/OS-II的Nios II系統。
使用環境：Quartus II 7.2 SP1 + Nios II 7.2 SP1 + DE2(Cyclone II EP2C35F627C6) + μC/OS-II
Introduction
本文為我較早期的文章，雖然仍有參考價值，不過並非最佳的設計，建議您一併參考(原創) 如何自己用SOPC Builder建立一個能在DE2上跑μC/OS-II的Nios II系統 (SRAM精簡版)? (SOC) (Quartus II) (Nios II) (SOPC Builder) (μC/OS-II) (DE2)
根據Altera原廠的資料，要讓Nios II上μC/OS-II，只要依照Using MicroC/OS-II RTOS with the Nios II Processor Tutorial這份資料照著做即可，不過這份資料有幾個問題：
1.這份資料是Altera為自己的開發版所寫的，儘管你照著步驟做，仍無法在DE2上執行。
2.他使用了已經編譯好的sof檔，若你主要是用於Nios II軟體的開發，可以採用這種方式。若你可能加入自己設計的硬體元件，則勢必重新編譯sof檔，很多人就是因為這樣而無法上μC/OS-II。
在(原創) 如何成功執行『Using μC/OS-II RTOS with the Nios II Processor Tutorial』? (中級) (IC Design) (Quartus II) (Nios II) (μC/OS-II) 中雖然克服了萬難讓Nios II上μC/OS-II了，不用總有個遺憾，為什麼只能用DE2原廠範例的DE2_SD_Card_Audio.sof呢?為什麼不能自己用SOPC Builder建立一個Nios II系統跑uC/OS-II呢?後來在Terasic原廠網站
http://www.terasic.com/downloads/cd-rom/de2/DE2_System_v1.4b.zip
中發現在這個目錄下
\DE2_demonstrations\SOPC_Builder\Reference_Design\DE2_NIOS\
有Terasic原廠所建議的Nios II硬體設計，經過一番研究後，整理出這份文件。
Solution
要讓Nios II軟體跑在on-chip memory並不是不可能，但DE2最多只能有49K的on-chip memory，所以若要讓軟體能跑，必須動一些最佳化的方式讓軟體盡量的小，在(原創) 如何在DE2執行Checksum Master範例 (中級) (IC Design) (DE2) (Quartus II) (Nios II) (SOPC Builder)用過幾個方式從軟體解決，有興趣的人可以參考，本篇主要是從硬體解決，直接將μC/OS-II跑在SRAM上。
Quartus II
使用Quartus II建立一個全新的project
Step 1：
建立一個新project
Step 2：
按Next下一步。
Step 3：
輸入project路徑名稱、project名稱與top-level module名稱，按Next下一步
Step 4：
c:/DE2/hello_ucosii目錄尚未建立，是否建立此目錄，按Yes繼續
Step 5：
加入既有檔案，由於我們目前沒有任何檔案，所以按Next下一步
Step 6：
選擇FPGA型號，DE2用的是EP2C35F627C6，按Next下一步
Step 7：
EDA工具設定，不需額外設定，按Next下一步
Step 8：
最後的Summary，按Finish
SOPC Builder
使用SOPC Builder建立一個全新的Nios II系統
Step 1：
啟動SOPC Builder
Step 2：
輸入System名稱：nios_ii，選擇Verilog
Step 3：
加入Nios II Processor
選擇左側Altera SOPC Builder->Nios II Processor，滑鼠按兩下加入
使用預設的Nios II/f即可，按Finish
Step 4：
加入SRAM
由於我們要將μC/OS-II放在SRAM跑，所以要加入SRAM controller，不過這裡有個值得注意的地方，你不能使用SOPC Builder所附的SRAM controller，必須改用Terasic本身所附的SRAM controller，將SRAM_16Bit_512K.7z下載，或者
http://www.terasic.com/downloads/cd-rom/de2/DE2_System_v1.4b.zip內的\DE2_demonstrations\SOPC_Builder\Component\SRAM_16Bit_512K
目錄複製到
C:\DE2\hello_ucosii\
複製完成後，請重新開啟SOPC Builder，就可以在左側的Altera SOPC Builder->Terasic Technologies Inc\發現SRAM_16Bit_512K這個contoller，滑鼠按兩下加入
Step 5：
加入Tristate Bridge
由於SRAM需要連接到Tristate Bridge的slave，所以需要加入Tristate Bridge controller，在左側Altera SOPC Builder->Bridges and Adapters->Memoery Mapped下找到Avalon-MM Tristate Bridge，滑鼠按兩下加入
按Finish即可，完成後如下圖出現了一個錯誤訊息：
錯誤訊息表示Tristate Bridge的master必須接到一個slave裝置，所以加上一個Flash Memory controller連上Tristate Bridge。
Step 6：
加入Flash Memory controller
在左側Altera SOPC Builder->Memories and Memory Controllers->Flash下找到Flash Memory(CFI)，按兩下加入，將Address Width(bits)改成22
加入後，會如下圖，發現tristate_bridge的tristate_master仍然沒和cfi_flash相接：
所以我們必須手動的接上去
Step 7：
加入JTAG UART
由於我們需在console顯示文字，所以需要加上JTAG UART
在左側Altera SOPC Builder->Interface Protocols->Serial下找到JTAG UART，滑鼠點兩下加入，接受預設值即可，按Finish
最後如下圖所示
Step 8：
加入Interval Timer
由於μC/OS-II需要用到Internal Timer，所以需要加上。
在左側Altera SOPC Builder->Peripherals->Microcontroller Peripherals下找到Interval Timer，滑鼠點兩下加入，接受預設值即可，按Finish
最後如下圖所示
Step 9：
加入System ID Peripheral
System ID Peripheral可以用來辨識硬體，雖然沒有加入也能執行，不過Altera原廠手冊仍建議加入此controller。
在左側Altera SOPC Builder->Peripherals->Debug and Performance下找到System ID Peripheral，滑鼠點兩下加入，接受預設值即可，按Finish
最後如下圖所示
Step 10：
解決錯誤訊息
上圖最下面有幾個錯誤訊息
Error : cpu.instruction_master:"cpu.jtag_debug_module"(0x800..0xfff) overlaps "cfi_flash.s1"(0x0..0x3fffff)Error : cpu.data_master:"cpu.jtag_debug_module"(0x800..0xfff) overlaps "cfi_flash.s1"(0x0..0x3fffff)Error : cpu.d_irq:Interrupt number conflict(jtag_uart, timer.irg) on 0
在
Error : cpu.instruction_master:"cpu.jtag_debug_module"(0x800..0xfff) overlaps "cfi_flash.s1"(0x0..0x3fffff)
點兩下，將Reset Vector選擇cfi_flash，Exception Vector選擇sram_16bit_512k_0，按Finish完成
Step 11：
重新分配Base Address
Menu的System->Auto-Assign Base Address
Step 12：
重新分配IRQ
Menu的System->Auto-Assign IRQs
Step 13：
新增Clock Settings
將原本clk改成100.0 Mhz
另外加上clk_50為50.0 Mhz
至此，一個能跑μC/OS-II最小的Nios II系統已經完成，而且是我們DIY用SOPC Builder完成的，最後完成圖如下。
最後按下Generate開始產生硬體，詢問是否儲存，按Save
需要一些時間，完全看你CPU速度而定。
Quartus II Top Module
至此我們還缺Quartus II的Top Module，建立一個新的Verilog檔，名為hello_ucosii.v

你一定會問，為什麼還要自己加上Reset_Delay.v和SDRAM_PLL.v，明明我只用到SRAM，卻還要用到SDRAM的pll?
這是參考友晶科技reference design的作法，所以加上Reset_Delay.v和SDRAM_PLL.v。
先談SDRAM_PLL.v，這是由MegaWizard透過MegaCore產生出來的code，主要有三個功能，c0產生SDRAM所需要的50MHz相位延遲60度的clock，c1產生100MHz給Nios II CPU使用，c2產生除頻的25MHz，由於要讓Nios II CPU跑100MHz，所以才動用SDRAM_PLL.v。
Reset_Delay.v則是延緩reset的時間，詳細理由我還不清楚。
根據實驗，若你願意只讓Nios II CPU只跑50MHz，的確可以不加SDRAM_PLL.v和Reset_Delay.v，依然可以正常運作。

在View->Utility Windows->Tcl Console出現Tcl Console
輸入
source pins.tcl
Step 2：
將沒用到的pin設為tri-state
Menu的Assignment->Device..
按下Device and Pin Options..
選擇Unused Pins tab，將Reserve all unused pins設為 As input tri-stated
至此，Quartus II部分已經完成，可以開始編譯產生.sof檔，這需要很久的時間，完全看你CPU速度而定，編譯完成後燒將hello_ucosii.sof燒進DE2。
Nios II IDE
Step 1：
建立Hello MicroC/OS-II project
Menu:File->New->Nios II C/C++ Application
Step 2：
選擇Hello MicroC/OS-II template，講指定nios_ii.ptf路徑，完成按Finish
Step 3：
執行hello_ucosii_0
選著hello_ucosii_0 project，右鍵Run As->Nios II Hardware
最後執行結果，表示μC/OS-II順利執行
完整程式碼下載
hello_ucosii_sram_big.7z (含SDRAM_PLL.v和Reset_Delay.v)
hello_ucosii_sram_small.7z (不含SDRAM_PLL.v和Reset_Delay.v)
Conclusion
DE2和Altera原廠的版子還是有些差異，很多Altera官方的文件並不適用，在本文又再次證明了這個事實。
