我用的是radxa-stable-3.0的内核源码，rk3188_sdk_defconfig的配置文件，arm-eabi-4.6的交叉编译工具，现有的initrd和rootfs，编译出来的内核zImage和initrd打包成boot.img，在和rootfs.img打包成update.img，启动，串口有一堆I2C设备地址的报错，应该是地址不匹配的问题，我在menuconfig里取消相应设备的勾选，暂时不管这个，现在我进入了initramfs，下面是目前的串口信息：

insmod: can't insert '/rk30xxnand-3.0.36+.ko': No such device or address
ls: /sys/class/mtd/mtd*[0-9]: No such file or directory
Gave up waiting for root device. Common problems:
- Boot args (cat /proc/cmdline)
- Check rootdelay= (did the system wait long enough?)
- Check root= (did the system wait for the right device?)
- Missing modules (cat /proc/modules; ls /dev)
ALERT! /dev/block/mtd/by-name/linuxroot does not exist. Dropping to a shell!
/bin/sh: can't access tty; job control turned off
(initramfs)
目前这个rk30xxnand-3.0.36+.ko模块挂载不了，/dev目录下也没有mtd和mtdblock，我想问，为什么配置里选了rk29xxnand还要挂载这个rk30xxnand，还有就是，会不会是parameter里有一行mtdparts=rk29xxnand:0x00008000@0x00004000(boot),-@0x000C0000(linuxroot)这个mtd_partition分区，要在源码里进行修改？还是说我的nand硬件地址和板级初始化的nand地址不匹配造成的？我在源码里找了半天也没找到相关的代码，只有一个mach-rk30目录下的devices.c文件里有一个
static struct resource resources_nand[] = {
{
.start = RK30_NANDC_PHYS,
.end = RK30_NANDC_PHYS + RK30_NANDC_SIZE - 1,
.flags = IORESOURCE_MEM,
}
哪位大神能帮帮我？？帮我看看这是什么问题？？拜托了！

我将root的路径改为root=/dev/mmcblk0p3就可以了，不知道为啥
