Re: eCos + goAhead probelm



Recently, I modify balloc() in balloc.c of goAhead.
I try to increase 64bytes at the line of malloc() . And the problem of out of memory disappeared.
So , I think it's not the probelm caused by eCos.
I think it's caused by goAhead somewhere that call balloc() and use wrong size.


Now, in my target, goAhead still unstable just like you say. Then I use very simple web page instead of default web page(home.asp).
It still unstable, but not crashed.
But it can work very fine when I use 'lynx' instead of other browser(IE, mozilla..).
I don't know what's the difference of behavior between lynx and other browser (IE,mozilla).


Hope this information can help you something.

Hello Hao!

I've got the same problem!
The target has eCos 2.0, and I use GoAhead 2.1.8 as well.

I'm using an improved kernel, with:
CYGPKG_NET_MEM_USAGE set to 512K (instead of 256K)
where NET_MEMPOOL_SIZE is 5/8 of CYGPKG_NET_MEM_USAGE (instead of 1/4)
CYGPKG_NET_MAX_SOCKETS set to 192 (instead of 16)

I increased 'bufsize' for bopen() to 192K, 256K, and more (instead of 60K).
I also tried to create a separate thread with a stack size of 80K (and
later 120K) and put the original main code inside ...

... But in all cases the web server was unstable, and crashed after some
play...

Any suggestion?

b.t.w. When I load the default GoAhead web site (home.asp),
it doesn't handle with the left side menu applet (classes/treeapp.jar) -
it just leaves it black (no error message!)
The same applet works fine on Linux.

Why does it behave like that?
Have you got this problem as well?

Thanks in advance,
-- Amir

I build a target system that use eCos + goAhead web server.
When I run goAhead , and try to open a page from browser.
My target is failed at malloc() reutrn NULL.
But the ping function still work.
I set CYGNUM_MEMALLOC_FALLBACK_MALLOC_POOL_SIZE from 16384 to 1638400.
But, it doesn't help.
Then I try to use 'Simple variable block implementation' instead of
'Doug Lea's malloc implementatioin'.
It still don't work.

My target system already pass all eCos tests include memalloc. And the
on board memory is
16MB. I think it's enough for eCos + goAhead.

It seems goAhead eat all of memory. why ?
Does anybody has same problem as I ?
I use goAhead 2.18 + eCos (2004/06/24 got from CVS).
(I already try goAhead 2.14 ~ 2.18. All that have same problem)

Regards
Hao
