呵呵，是这样的，你可能对uboot不是很熟悉，
Verifying Checksum ... OK
Loading Kernel Image ... OK
OK
Starting kernel ...
到这里，串口终端就没有再输出任何信息了.
以上的串口输出信息是uboot的引导过程，至于这个starting kernel其实是uboot阶段输出最后的一句信息，这时候正准备进入内核引导。
在这个阶段过后，uboot的工作才算做完，这个时候拔SD才与uboot无关。
然后我看了下你的报错，当检测不到sd的时候将会从nand下载内核，我在你的内核打印里面并没有看到关于nand初始化的信息，你的nand似乎跟我一样都没起来。
你从nfs起来试试吧，然后cat /proc/mtd ，看有没有分区信息输出
再看看/dev下面关于nand和mmc的设备驱动节点，应该都没有吧。
从他给出的信息来看，在mmc下的command line是[ 0.000000] Kernel command line: console=ttyO0,115200n8 androidboot.console=ttyO0 mem=256M root=/dev/mmcblk0p2 rw rootfstype=ext3 rootwait init=/init ip=off
在nand下，command line是Kernel command line: console=ttyO0,115200n8 root=/dev/mtdblock7 rw noinitrd rootfstype=jffs2 ip=none
不过他设备都没检测到，这些怎么改都没用的。
kernel boot argument：
bootargs=console=ttyO0,115200n8 androidboot.console=ttyO0 mem=256M root=/dev/mmcblk0p2 rw rootfstype=ext3 rootwait init=/init ip=off
bootcmd=mmc rescan ; fatload mmc 0 82000000 uImage ; bootm 82000000
uenvcmd=boot，请问您说的是在这里改么，改成bootargs=console=ttyO0,115200n8 androidboot.console=ttyO0 mem=256M rootfs=/dev/nfs rw rootfstype=ext3 rootwait init=/init ip=off
bootcmd=mmc rescan ; fatload mmc 0 82000000 uImage ; bootm 82000000
uenvcmd=bootrootfs=/dev/nfs
文件系统的分区吧，我刚才看了下board.3359.c，nand一共分区8个，0-7，这个mtd7就是filesystem，不过他检测到不到nand设备，哪个区文件系统都没用。
SD卡里有个uEnv.txt，里面内容：
bootargs=console=ttyO0,115200n8 androidboot.console=ttyO0 mem=256M root=/dev/mmcblk0p2 rw rootfstype=ext3 rootwait init=/init ip=off
bootcmd=mmc rescan ; fatload mmc 0 82000000 uImage ; bootm 82000000
uenvcmd=boot
请问您说的是在这个文件里改么，改成
bootargs=console=ttyO0,115200n8 androidboot.console=ttyO0 mem=256M rootfs=/dev/nfs rw rootfstype=ext3 rootwait init=/init ip=off
bootcmd=mmc rescan ; fatload mmc 0 82000000 uImage ; bootm 82000000
uenvcmd=boot
还是在编译kernel时改呢，要是编译kernel时在哪里改呢。
要是只改这个文档，结果是

bootcmd=mmc rescan ; fatload mmc 0 82000000 uImage ; bootm 82000000
uenvcmd=boot
您好，我是新手，有很多东西都不知道，有的您的提议我也不知道去哪里改，请原谅。我又看了些资料，是不是没有网口的话不能用nfs那种，还有有的资料中提及分区，我的卡是三块
查了许多资料照着改了还解决不了才来提问希望得到大家帮助的呢，uEnv.tet是开发板里的卡里带着的资料，看了许多说是改这个，可是照的哪个改还是出那个错，肿么办
这几天我又查了点资料，在code.google.com/.../LinuxBootDiskFormat 上看到一句话：Bootloader settings
If you use bootloader U-Boot, use following settings to mount root file system at second partition from kernel:
console=ttyS2,115200n8 root=/dev/mmcblk0p2 rw rootdelay=1
我觉得我一直停留在这里，是不是从内核的第二部分没有挂载上根文件系统，然后我processors.wiki.ti.com/.../How_to_Make_3_Partition_SD_Card 在这个网站了给SD卡分了俩区，一个fat32，一个ext3，把filesystem解压到ext3，把MLO、u-boot.img、uImage、uEnv.txt放到fat32，结果插上SD卡就只输出cccc了，请问这是怎么回事啊，这几天都不知道去哪里找问题了。
我又仔细看了processors.wiki.ti.com/.../TI-Android-GingerBread-2.3.4-DevKit-2.1.1_DeveloperGuide，原来有一块To generate SD/MMC card to boot Android，按着做就可以给SD卡分区并且把需要的复制进去，我也做了，分了3个区，并且每个里面都有文件，可是执行还是卡在那里，请问/mmcblk0p2...是什么意思啊，。。。
因为你的子板去掉了，读不到ID
ret = mem_acc->read(mem_acc, (char *)&config, 0, sizeof(config));
if (ret != sizeof(config)) {
pr_err("AM335X EVM config read fail, read %d bytes\n", ret);
pr_err("This likely means that there either is no/or a failed EEPROM\n");
goto out;
}
if (config.header != AM335X_EEPROM_HEADER) {
pr_err("AM335X: wrong header 0x%x, expected 0x%x\n",
config.header, AM335X_EEPROM_HEADER);
goto out;
}
if (strncmp("A335", config.name, 4)) {
pr_err("Board %s\ndoesn't look like an AM335x board\n",
config.name);
goto out;
}
经过高人的指点和这几天的摸索，对内核进行了修改，卡着的那步终于过去了，不过还是有错，请大家指导一下

后面这几句重复出现，一直在出，请问这是怎么回事
我开始使用的tisdk-rootfs-am335x-evm.tar.gz做的文件系统，遇到跟楼主一样的问题，后来用base-rootfs-am335x-evm.tar.gz做了一个就可以正常的启动了。
TI E2E 上有个回答 可能有帮助
It looks like your SD Card is not created properly. How did you create the card? The TI Wiki has some instructions here:
processors.wiki.ti.com/.../AM335x_U-Boot_User%27s_Guide
You might want to try a 1GB or 4GB card. The 2GB size can cause problems if your card reader is one of the older models. That size needs a MBR.
我的是修改了内核里面的配置才可以的，现在又卡到了另一处，估计还得改配置
