經過一陣子的努力，目前已經重新更新 ARM9 W90P950( NUC950 ) CPU 的 BSP，包含變更Linux 核心硬體驅動、加入 ftp server、加寫數支 EBI 驅動 IO 的驅動程式( 包含 LED*8、 LCD ... 等 )。
開機畫面如下：( 我貼上 整個 NUC950 執行 Linux 的畫面過程 )

接著，進入 /tmp 目錄，然後透過 ftp 將 LCD.ko 與 LEDAP.exe 傳到 W90P950( NUC950 ) 的 /tmp 目錄上，再來如下圖所示過程執行。 如下圖所示：
執行後，你會看到在 LCD 上，第一行顯示 "Hello CYH"，第二行顯示 "Hi Chiang,YiHua"；在七節顯示器上( Seg7 ) 會顯示 111、222~999；在 8 顆 LED 上會同時 亮( On )或 不亮( Off )。如下圖所示：
七節顯示器上( Seg7 ) 顯示 999、8 顆 LED 上同時 亮( On )
七節顯示器上( Seg7 ) 顯示 111、8 顆 LED 上同時 不亮( Off )
