改写了 一个 BootLoader<br /><br />-----与ViVi相似.<br />不过是基于ADS<br /><br /><br /><br />现象:<br />1,用ViVi可以启动Kernel <br /> Kernel command line: ....<br /><br /> 其中<br /> S3C24XX NAND Driver, (c) 2004 Simtec Electronics<br /> <br /> s3c2440-nand: mapped registers at c4880000<br /><br /> s3c2440-nand: timing: Tacls 9ns, Twrph0 39ns, Twrph1 9ns<br /><br /> NAND device: Manufacturer ID: 0xec, Chip ID: 0x76 (<br /> Samsung NAND 64MiB 3,3V 8-bit)<br /><br /><br />2,用自己改写的,启动Kernel <br /> Kernel command line: ....与ViVi启动 相同<br /><br />但是<br /><br /> s3c2440-nand: mapped registers at c4880000<br /><br /> s3c2440-nand: timing: Tacls 9ns, Twrph0 39ns, Twrph1 9ns<br /><br /> No NAND device found!!!<br /><br /><br />以上,Kernel 完全没改变-------仅仅把NAND 起始的BootLoader替换成ViVi或者把ViVi替换成BootLoader..........两者切换,为什么这样?<br />仅仅认不出NAND----导致无法mount FS<br /><br /><br /><br /><br /> |
