Re: [ECOS] Trouble using lwIP (driver crash...)

[Uwe Kindler]

Hello,

which file does include cyg/fileio/limits.h? I searched the whole lwIP 
stack sources but did not found any file that includes limits.h.

The nc_test_slave is currently not applicable because SO_REUSEADDR and 
SO_REUSEPORT are not supported at the moment and the nc_test_slave 
requires both.

Regards, Uwe

[Michael Grimard]

Hi,

When I compile without the File IO package I got:

In file included from
/my_path_to_ecos/ecos/packages/infra/current/src/diag.cxx:65:
/my_path_to_ecos/ecos_lwip_install/include/limits.h:175:37:
cyg/fileio/limits.h: No such file or directory

For nc_test_slave, I got the "Not Applicable" message when I ran it, but I
didn't try it before running nc_test_master, since nc_test_slave is part of
the tests that come with lwIP. Maybe, it needs to be remove?


Michael

This does not look like a direct lwip problem. 

Could you find out why limits.h is trying to include
cyg/fileio/limits.h. To me it seems like a configuration problem, but
i'm jumping to a conclusion with very limmited information. Could you
export your configuration and post it.

The reason the test has been kept is that we hope the upstream
maintains of lwip will put back the setsockopt() calls the test needs.

RE: [ECOS] Trouble using lwIP (driver crash...)

[Michael Grimard]

I found what cause limits.h to include cyg/fileio/limits.h.

In eCos Configuration Tool, under ISO C and POSIX infrastructure, there is a
Limits section. In this section, there are OPEN_MAX and NAME_MAX
implementation header that points to <cyg/fileio/limits.h>. Both were
checked.
I don't know why there were checked, since by default they are not. I
unchecked them and now the build works.


For the nc_test_slave, I will only test with the UDP part, so SO_REUSE will
not be a problem. I put this in comments, compile and run. When I ping it, I
got:

Stack base corrupt - i: 0
...
...
ASSERT FAIL: <A>thread.inl[119]void Cyg_HardwareThread::check_stack() Stack
base corrupt

Any idea what causes this?


Thanks,
Michael

Did you ran any other lwip test successfully? Does the tcpecho, udpecho 
and sockets tests work properly. Did you ran any other eCos tests 
successfully?

I ran udpecho with the same problem. I boost the "Size of per thread stack
in lwIP" to 32Kb and still got the same problem.

I enabled CYGFUN_KERNEL_ALL_THREADS_STACK_CHECKING and now I got:

Before using lwIP, I was using FreeBSD and every eCos tests passed. Now I am
not able to build all the tests. In eCos Configuration Tool, Build Tests

[Birahim Larou Fall]

compare your file  eCos\packages\net\lwip_tcpip\current\ChangeLog with my 
changeLog. I advise you to update the ecos sources (LWIP packages) if your 
changelog is different to mine.  I use the lwip an it's ok.. Before 
re-building library, I suggest you to delete the build tree yourself 
(three reportories: mlt, build and include) and generate again build tree. 
This can avoid some build errors.

[ECOS] Trouble using lwIP (driver crash...)

[Michael Grimard]

Hi,
  I have downloaded the latest source for eCos with the ported version of
lwIP (1.1.1) and I have some trouble with it.

With the eCos Configuration Tool, I choose i386 PC target with i82559
ethernet template with the lwip_eth package and this configuration doesn’t
compile. I got “cyg/fileio/limits.h: No such file or directory” error. In
fact, the directory cyg/fileio has not been created by the config tool. I
added the POSIX File IO compatibility layer package and now eCos builds
without errors. I guess that this package should be included by default…

I never used lwIP so I wanted to start with the nc_test_xxx examples to test
it, but nc_test_master.c is not given, so I started porting it to use lwIP.
The biggest problem I had with the code was that gethostbyname() and struct
hostent that are undefined.

struct hostent is defined in netdb.h or dns.h. I don’t have dns.h (the
directory “ns” has not been created by the config tool), so I must use
netdb.h, but by doing this, gethostbyname() gets defined to a function
returning NULL… That’s not really what I was expecting…

Does lwIP supports a call to gethostbyname()? If yes, how can I do it?

For now, I’m using the IP4_ADDR macro and nc_test_master compiles.

Now… my real problem. Is anybody have used lwIP with the i82559 driver?

When I run nc_test_master, the first packet sent triggers the ARP Protocol.
An ARP Request is sent, the reply from the slave is sent and the master
sends the first packet (NC_REQUEST_TCP_ECHO), but when the master receives
the ACK from the slave, I got:

ASSERT FAIL: <5>if_i82559.c [2008]PacketRxReady() No prev EL

Can anyone help me with this?

If someone has already the nc_test_master.c file modified for lwIP and can
send it to me, I will try it to see if it is the modification I made to the
nc_test_master.c file that causes this or something else (maybe eth_drv.c?).


Thanks,
Michael
