以下資料是給我自己做個以後查詢使用。
==================================================
手動清除EPCS內的資料步驟：
1. 先開啟 Nios II 1X.X Command Shell
2. 下指令
nios2-flash-programmer -e --base=0x1800 --erase-all --override=c:/nios2-flash-override.txt
參數說明:
-e : 這個動作只對 EPCS flash使用
--base : EPCS的基底位置 (base address)
--erase-all : 清除全部資料
--override: 指定EPCS的型式及磁區大小
