如何在没有嵌入式操作系统环境下启动lwip?

tiredcasper · 发表于 2006-3-18 11:10:25

网上看到的大多是uclinux等嵌入式操作系统之下移植lwip之后，再放到skyeye下仿真，我想直接把lwip放到skyeye下仿真，不知道该怎么做？

另外还有些问题：
1。lwip源代码包里面没有安装说明，我该怎么安装呢，有没有写好的应用程序的例子？
2。据说skyeye已经移植了lwip,不知道在哪儿可以看到，我down了最新的skyeye,并没有发现啊。而testsuits里面都是编译好的文件，是不是在这个里面？

不知道问题问的清除不清楚，请大家多多指教，万分感谢。

Please refer to http://skyeye.sourceforge.net/wiki/um1. The lwip is in ucosii4skyeye package.Downloadable from gro.clinux.org

when I try to access http://skyeye.sourceforge.net/wiki/um1 ,"This page doesn't exist yet. Maybe you want to create it?" appears.

ok,that page has been found.and now,
I wonder whether I can find the lwip example from the testsuites2.0 now.

ksh · 发表于 2006-3-20 14:15:12

There is no samples in testsuite 2.0. The lwip sample of ucosii only lies in http://gro.clinux.org/frs/download.php/1004/ucosii4skyeye-1.9.3.tar.gz . Please read the README in the package carefully.

ok,let me try .

I met a issue when I read the readme file in the ucosii4skyeye package.
in this file ,line 78 to 81 said:

"
Before you do step 2 to compile this project:
1. make sure you have arm-linux/elf-* cross-compiler installed on your computer
2. make sure you have these two file: 'libc.a' 'libgcc.a' under LIBPATH
( maybe you need to copy the file libc.a to LIBPATH by hand, I did it

"

then my question is where I can find these two file: "libc.a" and "libgcc.a".
sorry for this beginner's question,but still expect the answer here.

thanks a lot.

you can run "find" command in your arm-linux or arm-elf directory to get them. In my machine, I can find them in:
ksh@linux:/usr/local/arm-linux> find ./ -name "libgcc.a"
./lib/gcc-lib/arm-linux/3.2.1/libgcc.a

ksh@linux:/usr/local/arm-linux> find ./ -name "libc.a"
./lib/libc.a
./arm-linux/lib/libc.a

still found a error when making the lwip, info list blow:

"
skyeye_printf.o: In function `getnum':
/usr/src/skyeye-v1/ucosii4skyeye/samples/lwip_on_ucos_test/../../lib/skyeye_printf.c:110: undefined reference to `isdigit'

make: *** [lwip_on_ucos_test.elf] Error 1

"

and the arm-elf-tools-20030314.sh is installed. libc.a and libgcc.a has been put into the
LIBPATH.

have found solution from http://linux.tcpip.com.cn/~foolox/?id=9.

maybe ucosII4skyeye should be upgrade.

tiredcasper · 发表于 2006-3-22 20:16:41

It seems that tap can not be found. I have executed the command "insmod",
but when startup lwip and use command "lsmod", I find the tun module is not used.

help me please!!!

and I also tested uclinux with net under testsuite2/at91/uclinux_cs8900a,
when run this test, tap0 can be find.
but why the lwip can not find???
It's so strange.

tiredcasper · 发表于 2006-3-22 22:16:33

after add a type=cs8900a in net line,there is not error so far.
but MAC address is not initiated as " mac addr=0:0:0:0:0:0".

so It seems I should found a correct type....

help me....

ooops~~~,skyeye-0.9.4 is ok.

It seems Skyeye v1.2 needs more teest.
