請問espd_4510b skyeye.conf 的設定

morewatertw

使用
  uClinux-dist-20041215
   參考  http://opensrc.sec.samsung.com/document/Getting_Familiar_with_uClinuxARM2_6.html

   使用linux-2.6.9 & linux-2.6.9-hsc0.patch
   arm-uclinux-tools-base-gcc3.4.0-20040713.sh
    red hat 8
   skyeye-1.2-RC8.tar.gz

    可成功產生 romfs.img & linux

    使用skyeye 執行後
   我的command string 設定 root=/dev/ram0
   跑到VFS:unable to mount root fs on unkown block(1,0)停止
    查看網路資料後  應該是找不到file sysytem

    想請問espd_4510b的 defualt kernel command string 要如何設定
   或有相關的資料可提供?
     謝謝

ksh

place your romfs.img to a specific memory address in skyeye.conf. Such as:
mem_bank: map=M, type=RW, addr=0x01400000, size=0x00400000, file=./romfs.img

Then tell uClinux kernel where it should find kernel.

先谢谢 版主提供方法
照版主所说的试也无法启动
在kernel command string 设定好地址 initrd=0x00600000
Initializing Cryptographic API 这是后来出现的
还有问题就是我在skyeye-v1 看的s3c4510b.h
有这SDRAM_BASE0_R ((0x0000000>>16)<<10)  
跟SDRAM_NEST0_B ((0x0020000>>16)<<10)
R跟B到底是什么意义
那skyeye.conf 只要设定好地址 就会把kernel 跟 romfs.img load到RAM去执行跟在 menuconfig 设定 sdram flash 大小的地址有关系吗?
希望各位能够帮我看看 为何执行到如此 在此先谢谢各位

目前已解決問題 可以跑到命令列~~~
參考的文章 http://www.linuxfans.org/nuke/modules.php?name=Forums&file=viewtopic&t=107989

使用linux-2.6.9 & linux-2.6.9-hsc0.patch
改用 arm-elf-tool-20040427.sh
改用 red hat 9
      skyeye-1.2-RC8.tar.gz

我設定的default kernel command string
root=/dev/ram0  initrd=0x00A00000,700k keepinitrd

skyeye.conf 設定
#skyeye config file sample
cpu: arm7tdmi
mach: s3c4510b
mem_bank: map=M, type=RW, addr=0x00000000, size=0x00A00000
mem_bank: map=M, type=RW, addr=0x00A00000, size=0x00200000, file=romfs.img
mem_bank: map=M, type=RW, addr=0x00D00000, size=0x00300000
mem_bank: map=M, type=R,    addr=0x01800000, size=0x00200000
mem_bank: map=I, type=RW, addr=0x03ff0000, size=0x00100000
應該是記憶體位址 的設定關係

kernel command string 在哪啊？我怎么在menuconfig中找不到？

更新patch完後
在主選單內 會有兩個General Setup
選擇第二個

General Setup 選單內的後面幾個選項

       [ ]Preemtiple Kernel (EXPERIMEMTAL)
       (root=/dev/ram0 initrd=0x00A00000,700k keepinitrd)default kernel command string
       [ ]Kernel-mode alignment trap handler

哦，多谢，我试试看
