* 10/30修改
*測試: 0~64k的范圍內的flash一次寫入,分批讀出 . 成功.0~256k沒做測試
*一次性寫入64k數據用時大約30秒,在寫入完畢前,其它任務等待(搶占式),如果一次寫入數據小于1k
*任務間感覺不到延時.
*說明: 無論是讀寫flash還是擦除flash都是互斥的,由Sector_Status表示,為了以后擴充flash狀態定義為字節型
*10/31修改測試,解決了不能換頁的問題
////////////測試說明/////////////
在扇區0從低地址0x00000000~~~~0x000003FF寫入1k字節數據,
然后分別在以下地址讀取數據:
0x0000--0x000F 顯示0xE1,0xE2,0xE3,0xE4,0xE5,0xE6,0xE7,0xE8,0xE1,0xE2,0xE3,0xE4,0xE5,0xE6,0xE7,0xE8
0x03F0--0x03FF 顯示0xE1,0xE2,0xE3,0xE4,0xE5,0xE6,0xE7,0xE8,0xE1,0xE2,0xE3,0xE4,0xE5,0xE6,0xE7,0xE8
0x0400--0x040F 讀出全1,說明數據正確寫入扇區0即0頁頭1k的位置.
0x7FF0--0x7FFF 讀出全1
0x8000--0x800F 讀出全1
0x83F0--0x83FF 讀出全1
0xFFF0--0xFFFF 讀出全1
0x10000--0x1000F 讀出全1
0x103F0--0x103FF 讀出全1
注意:keil下不能仿真頁面切換,以上數據是在upsd3254bv上的實際運行情況.
