Your original e-mail said you were using 2.6.38 ("I have bringup WR linux 2.6.38 on a custom mpc8247 board"). > Can you let me why the probe error of the driver happens. No. There were a lot of fixes and improvements that went into this code since then, including removing hardcoded assumptions about the hardware that are described in the device tree with the current binding. If you don't want the fixes that come with a newer version, you're on your own repeating that work. -Scott ^ permalink raw reply [flat|nested] 30+ messages in thread

The failure is in the user code - in particular, udev is giving up with these errors: /sbin/udevstart: '/lib/libc.so.6' library contains unsupported TLS After that, all is lost as there will be no console, etc, for the rest of the system to use... You need to examine how you built the root file system and why you are getting these errors.

There was an issue with the file system. Now my board is up with the linux boot prompt . But ping is not working. The local loopback ping works. My phy chip BCM5221 is connected on port A I am using FCC1 as the MAC. I see that the intrrupt handler is being registered properly. And even the fs_enet_start_xmit() gets called and it returns with return NETDEV_TX_OK. When I do a ifconfig -a I see the TX packets count increases for the loop back device but not for eth0. I am using the wireshark tool to see any packets on the witr. But don't see any ARP packets coming out on the wire. Can you please suggest . Below are the logs. Attache dis the .dts file. I have commented the bcsr register part in the .dts is this required.

How to go about this problem? Depends on your setup: normally the real MAC is stored on some onboard configuration space (eeprom or flash). Afterwards there are multiple ways you could work aroun the problem: most elegant: make your bootloader replace the fake MAC with the real one within the dtb. Most simple one: have a startup script that reads the real MAC and does the ifconfig magic. Regards, Lorenz ^ permalink raw reply [flat|nested] 30+ messages in thread

I tried $ethaddr but I get extra : characters. Why would you do that at all? U-Boot will run fdt_fixup_ethernet() for all (at least AFAICT) supported architectures, which will replace "mac-address" and "local-mac-address" for all "ethernet?" interfaces in the device tree for which a corresponding "ethadd" / "eth?addr" environment variable is set.
