Am335x报错Waiting for root device /dev/mmcblk0p2...

根据AM335x的EVM进行裁剪做了块板子，移植android系统时出现以上错误，请问大家是怎么回事呢。

你确定你的文件系统烧写正确了么？

我给你个建议。当你内核下载完毕，就是到这里

## Booting kernel from Legacy Image at 82000000 ...

拔出你的SD卡，你等下看看报错，是不是还是在这里停下

[    1.250644] Waiting for root device /dev/mmcblk0p2...

alvin lu您好，按照您的指点，我试了试，

2631224 bytes read

## Booting kernel from Legacy Image at 82000000 ...

  Image Name:   Linux-3.1.0-g62911f8-dirty

  Verifying Checksum ...

这一块几乎是同时出来的，所以我卡不到您说的那个点上，拔出SD卡时已经运行到到Verifying Checksum ... ，到最后还是停在这里

[    1.250925] Waiting for root device /dev/mmcblk0p2...

请问这是哪里的问题，需要怎么解决啊？

似的，在am335x EVM上使用能够正确启动。

呵呵，我的意思只要内核下载完毕就行，无需卡在那个点上。

我要看到的结果是这个[    1.250925] Waiting for root device /dev/mmcblk0p2...

你在uboot下mmc可以检测到并且可以下载内核，理论上来说，硬件特性问题不大。

这样吧，你设置rootfs=/dev/nfs ，尝试从nfs启动linux，系统启动完之后，ls /dev 看看，有没有mmcblk0的设备驱动节点。我觉得结果应该是没有的。

要是拔SD卡拔的早了，就是再reading uImage之后拔，就找不到SD卡了，

你的uboot给kernel的command line是啥啊

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。

按照上面的信息，很明显，他用的是默认的env，并且启动方式设置为mmc0为第一优先级，其次是nand。

默认的env大家的板子似乎都一样。

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。

要是不确定的话，我建议在设备Init阶段加一些打印信息，如果什么都没有打印出来，那么就证明设备根本没有init。

请问nfs是网络文件系统么，可是板子上没有网口啊

/dev/mtdblock7 这个是怎么来的

呵呵，没网口？这调试起来就纠结了。从硬件上跟EVM对比下吧，我没有板子，不能确定的事情太多，意见也只能给到这里了。

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

你的server上大好了nfs server么？你用你的pc去mount这个nfs server看看

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

您说的这个挂载nfs server是不是得联网才可以，没有网口的话应该是不行吧

是的，你先google下吧

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

你看看processors.wiki.ti.com/.../AM335x_U-Boot_User%27s_Guide， processors.wiki.ti.com/.../Sitara_Linux_Software_Developer%E2%80%99s_Guide

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，。。。

你这个情况我后来也遇到了，我能告诉你的是，你编译内核的时候有文件没改对。硬件是没有问题的。

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

请问下 你做了什么修改？我现在也遇到和你一样的问题

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

你好 我也遇到这个问题了 请问下你是怎么修改配置解决这个问题的  内核里面哪些选项做了修改 谢谢

我只是修改了board_am335xevm.c，只是这里过去了，别的还有错，你可以参考下我的改的，这个路径是kernel/arch/arm/mach-omap2

问题解决没 求赐教
