TQ6410烧写文件系统重启系统不能看到触摸屏界面

    我是嵌入式ARM新手，TQ6410开发板是我接触的第一块开发板，最近我想把所有光盘自带的镜像文件烧写一遍，下面是U-BOOT下载模式终端的菜单
#####    Boot for SKY6410/TQ6410 Main Menu      #####
#####     EmbedSky USB download mode     #####
[1] Download u-boot or STEPLDR.nb1 or other bootloader to Nand Flash
[2] Download Eboot (eboot.nb0) to Nand Flash
[3] Download Linux Kernel (zImage.bin) to Nand Flash
[4] Download LOGO Picture (logo.bin) to Nand  Flash
[5] Download UBIFS image (root.ubi) to Nand Flash
[6] Download YAFFS image (root.bin) to Nand Flash
[7] Download Program to SDRAM and Run it
[8] Boot the system
[9] Format the Nand Flash
[0] Set the boot parameters
[a] Download User Program
[n] Enter TFTP download mode menu
[r] Reboot u-boot
[t] Test Linux Image (zImage)
Enter your selection:

我具体的步骤如下：
1.选择9格式化NAND FLASH
2.用SD卡烧写U-BOOT，重新启动板子后在终端可以看到上面的U-BOOT下载菜单；
3.U-BOOT模式下重新烧写了U-BOOT（跟上面的第二步的可能重复），烧写完终端显示正常；
4.烧写自带的3.0版LINUX内核镜像；终端显示正常；
5.烧写文件系统（镜像名称为root_TQ6410_PDA_SLC_V1.1.ubi）终端显示如下：
    Now, Downloading [ADDRESS:0xc0000000,TOTAL:0x446a000]

   Creating dynamic volume rootfs of size 253919232
   Volume "rootfs" found at volume id 0
   Write UBIFS to rootfs, please wait ...OK.
   UBIFS write compilete!
6.最后烧写logo，终端显示正常；
7.重启系统，最后终端显示的最后几行如下：（不好意思，下边的可能显示的有点多，我选择性的删了一点，最后一行是启动系统后显示的最后一行）

完成了上述步骤后，终端就停在上面的最后一行TQ6410 Camera Interface Init success !，板子上面也没有看到触摸屏界面，只有一个embedsky的logo.我不知道接下来怎么做，所有的镜像都是光盘里自带的，我根据板子的内存256M（K9F2G08），显示屏是7英寸的选择了正确的镜像文件，不知道为什么结果是这样，试了很多回了，望路过的朋友能指点小弟，感激，感激

亲，我想问一下，你的开发板的内存是128MB的还是256MB的？根据你的情况，你应该是烧写镜像时选错了对应内存的镜像引起的（Linux的烧写，只有u-boot区分内存）。

内存芯片是三星的K9F2G08U0.这个是256M的没错。下面是我烧写的镜像名称和说明：
logo_A70.bin                                适合7寸屏的logo镜像
u-boot_nand_256MB_A70_V1.1.bin               适用于256MB内存，7寸屏NandFlash启动
zImage_3.0_A70_V1.1.bin                版本为3.0内核源、适合7寸屏的内核镜像
root_TQ6410_PDA_SLC_V1.1.ubi                适合TQ6410开发板SLC类型的PDA图形界面文件系统镜像
我想明天上午再重新格式化一遍，再重新走一遍上述过程，看看问题能不能解决，谢谢您的回答，有问题也请您指正

感谢亚瑟王的提醒，问题给我解决了，我把内存与NAND FLASH的概念混淆了，开发板上内存是128M，NAND FLASH是256M,之前的错误是因为，我把内存理解为NAND FLASH.再次感谢您。附件是我写的一个总结，希望可以帮助遇到类似问题的基友。

谢谢你的总结，那我结贴了哦。
