<哥哥姐姐们，求。。。助！>RTL819x_SDK_V2.5内核编译出错啦~~~~~~
小弟在编译rtl8196c内核的时候出错了，我根据帮助文档来的，文档里给的步骤是：

1. Build Environment

  Fedora 9

  Ubuntu 8.10/9.10



2. Quick start

  - tar xjvf rtl819x.tbz2

  - cd rtl819x/

  - make menuconfig:

--for 8196c

Select Target(rtl8196c)

Select Kernel (linux-2.6.30)

Select Busybox (busybox-1.13)

Select toolchain (rsdk-1.3.6-4181-EB-2.6.30-0.9.30)

Selected Target of SDK (11nRouter_GW) --->

Select Board Configuration(SPI flash + Squashfs)

Select Load default settings

--for 8196c-pocketAP

Select Target(rtl8196c)

Select Kernel (linux-2.6.30)

Select Busybox (busybox-1.13)

Select toolchain (rsdk-1.3.6-4181-EB-2.6.30-0.9.30)

Selected Target of SDK (11nPocket_Router) --->

Select Board Configuration(SPI flash + Squashfs)

Select Load default settings

-- for 8196c MP

Select Target(rtl8196c)

Select Kernel (linux-2.6.30)

Select Busybox (busybox-1.13)

Select toolchain (rsdk-1.3.6-4181-EB-2.6.30-0.9.30)

Selected Target of SDK (11nRouter_GW) --->

Selected Board Configuration (MP)

Select Load default settings

--for 8198

Select Target(rtl8198)

Select Kernel (linux-2.6.30)

Select Busybox (busybox-1.13)

Select toolchain (rsdk-1.3.6-5281-EB-2.6.30-0.9.30)

Select Board Configuration(SPI flash + Squashfs)

Select Load default settings

--for 8198 MP

Select Target(rtl8198)

Select Kernel (linux-2.6.30)

Select Busybox (busybox-1.13)

Select toolchain (rsdk-1.3.6-5281-EB-2.6.30-0.9.30)

Select Board Configuration(MP)

Select Load default settings

--other combinations please refer to 'user guide' for more details

  - make





3. make image

  there are four steps for making image:

  - make users

  build the users applications

  - make linux

  build the kernel files

  - make romfs

  copy all the application binary files into romfs

  - make image

  compress the root.bin and linux.bin

因为我要给板子烧一个支持nfs文件系统的系统。所有在make linux之前make linux_menuconfig设置Network File System，添加了nfs文件系统。但是最后make image会报错：
/home/weizhengh/RTL8196_SDK/rtl819x-sdk-v2.5/rtl819x/users/goahead-2.1.1/LINUX/cvimg linux-ro nfjrom linux.bin 0x80500000 0x30000

Error!!!! : Kernel image too big will overwirte rootfs image, cur size(891922), available size(851968).

我就截一点点日志了。前辈们你们知道这是为什么吗？我该怎么做？谢谢了~~~

------解决方案--------------------
flash重新分区吧。
------解决方案--------------------
看起来是内核过大
------解决方案--------------------
cur size(891922), available size(851968)
内核大小为891922大于可用空间851968.
------解决方案--------------------
重新设计并划分FLASH的分区，前提是FLASH的物理容量支持那么大的容量。
