[ECOS] eCos problem: if_lancepci.c does not compile for i386 (vmWare)

[ECOS] eCos problem: if_lancepci.c does not compile for i386 (vmWare)

[Waskita Adijarto]

I've just found problem compiling if_lancepci.c under eCos. After 
googling , I found similar problem in the archive here:  
http://www.mail-archive.com/ecos-discuss@ecos.sourceware.org/msg09854.html. 
I used similar new gnutools 
(ecoscentric-gnutools-i386-elf-20081107-sw.cygwin.tar.bz2)
I experienced this problem while compiling eCos 3.0 and 1.0.8 (from 
gaisler) in cygwin

Tool chain version:

    $ i386-elf-gcc -v
    Using built-in specs.
    Target: i386-elf
    Configured with: /gnutools/src/toolchains/gcc/gcc-4.3.2/configure -v --target=i386-elf --prefix=/gnutools/builds/toolchains/i386-elf/tools --with-newlib --with-gnu-as --with-gnu-ld --enable-languages=c,c++ --disable-__cxa_atexit --enable-threads --with-bugurl=http://bugs.ecos.sourceware.org/ --with-pkgversion='eCosCentric GNU tools 4.3.2-sw'
    Thread model: single
    gcc version 4.3.2 (eCosCentric GNU tools 4.3.2-sw)
      

My solution: use old gnutools 
(ecoscentric-gnutools-i386-elf-1.4-2.cygwin.tar.bz2) . The problem goes 
away.

tool chain version:

    $ i386-elf-gcc -v

    Reading specs from /opt/gnutools/i386-elf/bin/../lib/gcc-lib/i386-elf/3.2.1/specs

    Configured with: /local/demonweb/tools/ecos-gnutools-v1.4/r2/i386-elf/cygwin/tar_bz2/source/gcc-3.2.1/configure --target=i386-elf --prefix=/local/demonweb/tools/ecos-gnutools-v1.4/r2/i386-elf/cygwin/tar_bz2/opt/ecos/gnutools/i386-elf --enable-languages=c,c++ --with-gnu-as --with-gnu-ld --with-newlib --with-gxx-include-dir=/local/demonweb/tools/ecos-gnutools-v1.4/r2/i386-elf/cygwin/tar_bz2/opt/ecos/gnutools/i386-elf/i386-elf/include
    Thread model: single

    gcc version 3.2.1
      

I wonder why gcc 4.3.2 behave so different than 3.2.1

[ECOS] Ethernet controllers..

[Jim Bradleigh]

Hi,

Thought I would throw this out to the list to see if anyone can help...

As everyone know's eCos supports a limited device driver list for each platform, I`m currently running on i386 which limits me to a real-tek and two Intel chipsets...

Where do most of you purchase network controllers from? I can`t find any network cards which say they contain the Intel i82544 chipset.. It would be nice to start my project with a defined hardware spec that I know I can purchase..

One other question, does anyone know if a network card with the Marvell 88E1111 chipset exists?

Thanks,

Jim

The easiest route is probably a D-Link DFE-530TX+ PCI card which uses
the RTL8139 part and can be found via Amazon in the UK.

The i82544 featured on the Intel Pro/1000 ethernet card which appears to
have been replaced by the Pro/1000 GT card:

http://www.intel.com/products/desktop/adapters/pro1000gt/pro1000gt-overview.htm

The newer card uses the i82541 part which may or may not be compatible.

The 88E1111 is an ethernet PHY (transceiver), not a controller.

I hope this helps.

Hi John,

Thanks for the update, I`m currently using RTL8139 based cards but my project requires alot of performance from the network elements and eventually Gigabit Ethernet..

In this reguard I`ll have to look into Intel cards sooner or later, can anyone tell me why the Intel 82544 driver uses the function "udelay" alot - I`m concerned that the udelay is a hardware delay which will prevent threads (or other 82544 cards in the system) from running.

None of the uses of udelay are in the main processing path - only
during initialization.

Re: [ECOS] Re: Ethernet controllers..

[Jim Bradleigh]

Hi Gary,

If bring up the network cards using my own processes (as I currently do with a "custom" RTK 8139 driver) how would I go about replacing the udelay's with a more thread friendly process? Just a matter of "cyg_thread_delay" instead?

As previous described I only use eth0 with the FreeBSD stack, the other two ethernet ports are spoke to directly by my application and I just want to avoid any pitfall early on when I have to brief the powers that be in my work...

Thanks,

Jim

Re: [ECOS] Ethernet controllers..

[David Brennan]

I think you will run into this
(http://sourceware.org/ml/ecos-discuss/2004-11/msg00191.html) if you
attempt to instantiate two different Ethernet drivers based on the
eCos code. I never did need to actually do anything with this, so I
don't have any code to share. Of course since you plan on modifying
one of the drivers, you can modify the relevant parts of that as well.

Good luck.
David

[ECOS] Ethernet controllers..

[Jim Bradleigh]

Hi,

I`ve a question regarding Ethernet controllers.

My platform is a i386 with 3 ethernet PCI controllers (but before you turn off, its more eCos related than platform). eCos only knows about the first controller, the other 2 use 'custom' drivers (copies of the original eCos ethernet driver but with a different interface for raw read/writes)

Is there any problem with using a different controllers? Say the main controller (eCos owned and operated) being a realtek card, whilst the other 2 being Intel based?

My concern is that there might be some PCI problems as I`ve read that u can`t mix drivers due to some PCI issues (but I think this might not affect me as eCos think's there's only one ethernet controller, the realtek card)

Regards,

Jim
