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
