有人下載OpenWRT原始碼自己Compile過嗎?

因工作上的需要想請教一下
有台d-link dir-600 b1機器
Ralink 3050
Flash 4MB
Ram 32MB

那原始碼要在哪下載?如何Compile?
U-Boot也要更新嗎?

老闆又出難題給我了

:cry:

我是用VirtualBOX灌Ubuntu 10.10 X64
之前做出來的檔案燒進機子進不了內核 不知道哪錯了 !

[URL="http://wiki.openwrt.org/toh/d-link/dir-300revb"]D-Link DIR-300 B1 and D-Link DIR-600 (B1 & B2) - OpenWrt Wiki[/URL]

想問一下原始碼
trunk
backfire
的版本有啥不一樣阿
另外還有SDK可以下載的壓縮檔案又是?

我核心好像沒抓到mtd分割區 這是?
是用8MB NOR Flash ~

我的問題是:
Kernel command line是否要修改?
在kernel mount rootFS之前的MTD分割配置是依據Kernel command line的數據配置 還是依據mach-dir-600-a1.c (OpenWRT原始碼裡面) ?

感謝~

理論上應該不需設定 "root=/dev/mtdblock4" 和 "init=/etc/preinit", 也不必修改mtdparts (參見ralink-flash.c), 其實以上目的應該就是採用OpenWrt 預設值, 甚至清除bootargs 應該也無妨

[QUOTE=BizonGod]Now first problem is current linux kernel has no EN25Q80A JEDEC ID, so it hungs on no rootfs. Here is the clue:

In file linux-2.6.32.27/drivers/mtd/devices/m25p80.c add line:
{ "en25p64", 0x1c2017, 0, 64 * 1024, 128, },

大哥你好
想請教一下關於ＭＡＣ　ＡＤＤＲＥＳＳ
是否可以在Ｕ－ＢＯＯＴ下設置環境變數放ＭＡＣ　ＡＤＤＲＥＳＳ
然後在丟給ＫＥＲＮＥＬ去設置ＬＩＮＵＸ下網卡的各個位址？

你好像已經忘記曾經提過類似問題, 建議到數位天堂提問, 請站長Aven 和網友hippo 幫忙, 如果你的英文程度還過得去的話, 那麼更好的去處則是OpenWrt 論壇, 請恕小弟失陪了
