wince eboot之flash管理问题 [复制链接]

我使用S3C2410芯片和K9F1208的FLASH。现在我的EBOOT可以实现直接下载NK.BIN并在RAM中启动，但是无法在FLASH中启动。
超级终端显示如下：
TFTP: Desktop losing ACK, block number = 18570, Ack again
TFTP: Desktop losing ACK, block number = 32099, Ack again

另外eboot格式化FLASH功能也不好使
大家帮帮忙，看看该如何解决

看样子，所有的Block都会被提示bad了。
先检查你的eboot里的flash部分的程序。重点是EraseBlock的，如果找不到问题就贴代码。

BP_LowLevelFormat: no good blocks

全部都被标记为了坏块。。。还怎么下载呢

全部被标记为坏块，估计驱动有问题

OpenPartition: Invalid MBR.  Formatting flash.
主引导程序MBR（Master Boot Record）错误。
检测MBR的有效性。通过函数IsValidMBR（）实现。

检测MBR的有效性，首先要知道MBR保存在哪里，前面说过NANDFLASH的第0 BLOCK，第1 Sector为主引导扇区，也就是MBR，但是NAND如果被当作启动芯片，○地址一般被BOOTLOADER代码占据，MBR只有放在后面的BLOCK中。所以我把第0 个BLOCK放NBOOT，第1个BLOCK放TOC，第2个BLOCK放EBOOT，第3个BLOCK保留，第4个BLOCK就放MBR。

1. 
   
2. static BOOL IsValidMBR()
   
3. 
   
4. {
   
5. 
   
6.     // Check to see if the MBR is valid
   
7. 
   
8.     // MBR block is always located at logical sector 0
   
9. 
   
10.     g_dwMBRSectorNum = GetMBRSectorNum();        
    
11. 
    
12. 
    
13. 
    
14.     RETAILMSG (1, (TEXT("IsValidMBR: MBR sector = 0x%x\r\n"), g_dwMBRSectorNum));
    
15. 
    
16.    
    
17. 
    
18.     if ((g_dwMBRSectorNum == INVALID_ADDR) || !FMD_ReadSector (g_dwMBRSectorNum, g_pbMBRSector, NULL, 1)) {
    
19. 
    
20.        RETAILMSG (1, (TEXT("IsValidMBR-----return FALSE-------------------\r\n")));
    
21. 
    
22.         return FALSE;  
    
23. 
    
24.     }   
    
25. 
    
26.     return ((g_pbMBRSector[0] == 0xE9) &&
    
27. 
    
28.          (g_pbMBRSector[1] == 0xfd) &&
    
29. 
    
30.          (g_pbMBRSector[2] == 0xff) &&
    
31. 
    
32.          (g_pbMBRSector[SECTOR_SIZE_FS-2] == 0x55) &&
    
33. 
    
34.          (g_pbMBRSector[SECTOR_SIZE_FS-1] == 0xAA));
    
35. 
    
36. }

很同意这种观点，肯定是你的flash 驱动有问题。

我解决了，谢谢大家是
loader.h里面有个参数错了
