gnand使用求助

发表于 2010-8-12 21:12

在950开发板上，Nand Flash的使用上有点问题，请指点一下：

sh-3.2# insmod gnand.ko
sh-3.2#
scsi1 : Nuvoton W90XX900 GNAND DRIVER!
sh-3.2# call init
  Vendor: NUVOTON Model: GNAND DRIVER    Rev: 2.00
  Type: Direct-Access                   ANSI SCSI revision: 00
SCSI device sdb: 63936 512-byte hdwr sectors (33 MB)
sdb: Write Protect is off
sdb: got wrong page
sdb: assuming drive cache: write through
SCSI device sdb: 63936 512-byte hdwr sectors (33 MB)
sdb: Write Protect is off
sdb: got wrong page
sdb: assuming drive cache: write through
sdb:disk_0:sdb
unknown partition table
sd 1:0:0:0: Attached scsi removable disk sdb

Nand Flash中是空的，我想把Flash mount到/mnt/nand目录下，然后往里面写点LOG文件一类的东西，文件系统采用JFFS2 或其他文件系统，该怎么做？

另外，在我自己设计的电路板上贴的是4GB的Nand Flash（Samsung 822 K9LBG08U0M），运行insmod gnand.ko，输出如下：
sh-3.2# insmod gnand.ko
sh-3.2#

这次初始化就失败了，有可能是什么原因？

芯唐的gnand只能使用vfat文件系统。
jffs2的话使用nor。

还有一个问题，三星的4GB Nand Flash初始化失败。
在我自己设计的电路板上贴的是4GB的Nand Flash（Samsung 822 K9LBG08U0M），运行insmod gnand.ko，输出如下：
sh-3.2# insmod gnand.ko

这次初始化就失败了，有可能是什么原因？不提供source code，调试一下都没有机会，不知道哪里出问题了

GNAND的example运行也有问题
RawDataTest.c:
int main()
{
      int volatile i, data, totalSec, sectorNo;
      unsigned char *pSrc, *pDst;
      int volatile btime, status, errFlag=0;  ?
      WB_PLL_T sysClock;
      NDISK_T *ptNDisk;

      sysClock.pll0 = PLL_200MHZ;
      sysClock.pll1 = PLL_133MHZ;
      sysClock.cpu_src = CPU_FROM_PLL0;
      sysClock.ahb_clk = AHB_CPUCLK_1_2;
      sysClock.apb_clk = APB_AHB_1_2;
      sysSetPLLConfig(&sysClock);

#if 1
      sysDisableCache();
      sysInvalidCache(); â

      sysSetMMUMappingMethod(MMU_DIRECT_MAPPING); ÿÿ
      sysEnableCache(CACHE_WRITE_BACK);
#endif

      pSrc = (UINT8 *)(0x81000000);
pDst = (UINT8 *)(0x81600000);

AXD调试器中,一执行sysSetPLLConfig(&sysClock),JTAG就跑飞了.没办法来检查NAND Flash的问题。

不要选择sd和mmc在看看。

。。。。，这是谁在问问题呢

问题有点多了，而且好像说的也不太清楚
