移植文件系统出错（已解决）

在2440上移植文件系统错误，首先编译内核没问题，和手册一样，但是安装busybox之后，按照步骤制作yaffs文件系统，烧到开发板之后始终显示控制台不能打开，如下：
EmbedSky-buttons initialized
S3C24XX RTC, (c) 2004,2006 Simtec Electronics
s3c2410-rtc s3c2410-rtc: rtc VFS: Mounted root (yaffs filesystem).
Freeing init memory: 116K
Warning: unable to open an initial console.
Failed to execute /linuxrc.  Attempting defaults...
Kernel panic - not syncing: No init found.  Try passing init= option to kernel.
*** Warning - bad CRC or NAND, using default environment

控制台不能打开，查了很多资料，主要都是说dev下面两个文件的问题，然后各种改文件权限，重新用命令（虽然两个文件都是空），然而没什么用。
然后怀疑是内核传递参数问题，因为打印出许多坏块，或者是nand驱动问题，或者DNW烧写地址问题（上次因为小文件问题吃过亏），又去研究了内核传递参数和ecc设置，然而还是没用；
接着做了个重要的对比，将TQ自带的一个256M适用的QT文件系统烧写到开发板，可以运行，立马就排除了内核等等一系列问题，肯定的就在自己生成的文件系统了；
接下来又按照手册，一步步将文件系统制作一遍，依然那个问题，很多坏块，打不开控制台。然后将busybox设置又顺了一遍，完全按照手册的点，反复不下5次，依然。换了TQ自带的文件系统源码，用busybox生成，问题更坏，坏块打印到一半就死机了。
今天继续弄，先核对busybox是否跟内核有关，然后在官网下个原生的busybox，弄了还是不行。在路上查CSDN有说跟yaffs工具有关的，又去busybox找yaffs工具准备重新来，结果busybox工具里面没有make，但是分明记得是当时在工具下make出的yaffs工具，心里觉得焦急的瞬间也觉得有哪点有个闪光，然后找TQ的工具包里，重新将那个yaffs工具复制过去，制作，下载，成了！！！
当时就激动了，就前面驱动搞了那么久，就为linux，又韦东山的前几章都遍了就差移植系统，结果翻越重重大山走到拉萨门口你不让进，那一刻真的。。。
冷静下来复盘当时的情景，yaffs工具是从yaffs2工具文件夹make出来的，对比和TQ提供的，大小也不一样，y印证了工具不对的说法。后面继续研究下工具生成到底哪里不对，但是这个坎先过了。
贴上正确和错误的两种打印，有相似情况的可以有个思路
