[ECOS] Problems initializing eth0 interface

[ECOS] Problems initializing eth0 interface

[Bruno Ricci]

Hi all,

I'm trying to build eCos to be run on VirtualBox, which has an AMD PCNET 
network card. I made an i386 target with i82559 and the "net" package, 
and I removed:

-CYGPKG_DEVS_ETH_INTEL_I82559
-CYGPKG_DEVS_ETH_I386_PC_I82559

and added the package CYGPKG_DEVS_ETH_AMD_PCNET to adapt this 
configuration with VirtualBox environment. I tried to run several tests 
(i.e. ping, ...) but I found out that the variable 
CYGHWR_NET_DRIVER_ETH0 is never initialized.

Any suggestion (even for another ethernet card like Broadcom BCM5906M, 
Intel PRO/1000 MT Desktop, Intel PRO/1000 T SERVER or INTEL PRO/1000 MT 
SERVER)?

Thanks in advance,

Bruno

Ethernet drivers generally come in two parts. There is a generic
chipset part, which can be used for all platforms and there is a
platform specific part, which ties the generic part to the specific
hardware target. That is why you had to remove two I82559
packages. You would similarly need to add two PCNET packages to make
that work. Unfortunately, it looks like nobody has made the PCNET
driver work in a PC target:

See the above list.

Hi again,

I tried the same configuration with RTL8139 chip and without removing
any package (I managed to have a pc with that chip) with no luck. Here
some screenshots:

http://files.getdropbox.com/u/1493094/ecos1.jpg
http://files.getdropbox.com/u/1493094/ecos2.jpg

Notice that my program only initializes the network card, and that
there's a 20 sec sleep between the two screenshots. I tried to set a
static IP, but I keep on having that SIOCIFADDR error.

Thanks again for support

Bruno

The second screenshot shows your hardware address to be 
FF:FF:FF:FF:FF:FF. This is the Ethernet broadcast address and it's not a 
good idea to use it as your MAC.

Try setting a valid MAC address. The first byte should be 0x00 and the 
others you are free to choose. Eg 00:ab:cd:ef:01:23 would be reasonaby 
safe. Make sure the address doesn't conflict with anything else in your 
network.

If you have RedBoot, change the MAC address using fconfig. If not, then 
the MAC address can be hardcoded via eCos configuration tool (look under 
"I/O sub-system", "Common ethernet support", "Your ethernet driver").

http://en.wikipedia.org/wiki/MAC_address

If you are making up your own address, you should set bit 1 of the top
byte, to indicate this is a locally administered address.

I assume you have switched to the eCos "pc_rltk8139" target.

The reported hardware address (ff:ff:ff:ff:ff:ff) is bogus which
suggests that eCos is failing to interrogate your ethernet hardware
correctly. Try disabling the ethernet hardware in your PC's BIOS and see
if the behaviour is the same. If it is, perhaps your ethernet hardware
is reporting a PCI vendorID/deviceID pair which is not known to the eCos
driver? Check the known_8139_aliases[] array in the driver and extend it
if necessary.

I hope this helps...

Good to hear this resolved the problem you were seeing.

What was the PCI VendorID/DeviceID for your RTL8139 ethernet hardware?
