Hi
I have bringup WR linux 2.6.38 on a custom mpc8247 board. Not able to
configure the ipaddress. When I boot my linux kernel I get the below
message.
Also I am using the fec 1. The fec is not getting initialized.
fs_enet.c:v1.0 (Aug 8, 2005)

Can you attach your device tree? What sort of mdio do you have on your
board?

Hi Scott,
Below is the .dts file. My board is based on mpc8247. Currently using
FCC1.
This device tree is based on something very short-lived when 82xx
support was first being worked on for 82xx, around 2.6.24 or so. Please
redo it from scratch based on what is in the current kernel.

Thank Scott. I am working on a legacy project Which is using 2.6.21
linux kernel so the device tree is based on that.
Can you let me why the probe error of the driver happens. So that I can
keep a patch in the code.Or What exacly in the device tree it is
missing. That would be of great help.
Thanks & Regards,
Smitha

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.

Hi Scott,
I am currently trying to bring up 2.6.39 kernel on a target based on
MPC8247
Processor, using the attched .dts file . I get the below logs while the
kernel is booting.
I see that the unflattening of the device tree and the initial loading
of the kernel and ramdisk file system is happening correctly. Can you
point me where exactly I can look for this issue. I am attaching the
.config and .dts file I am using.

There doesn't seem to be anything wrong with the kernel in this log.
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. This problem seems to be unique to uclibc

Which error are you referring to?
of-flash ff800000.flash: do_map_probe() failed
What kind of flash chip do you have? Does the node in the device tree
accurately describe it (four interleaved 8-bit chips that only do JEDEC
and not CFI)?
Thanks scott.
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.

You still haven't set your MAC address. U-Boot should be fixing this up

The local loopback ping works. My phy chip

Your device tree describes a connection on port C. You need to update
the mdio node's reg to point to port A's registers (0x10d00), and
fsl,mdio-pin and fsl,mdc-pin need to be set to the particular pins your

Hi Scott,
In my DTS file for mpc8247 I have defined the ether MAC in the node as below=
.
ethernet@24000 {
#address-cells =3D <1>;
#size-cells =3D <0>;
device_type =3D "network";
device-id =3D <1>;
compatible =3D "fs_enet";
model =3D "FCC";
reg =3D <11300 20 8400 100 11380 30>;
mac-address =3D [ 00 e0 ee 00 05 2e ];
interrupts =3D <20 2>;
interrupt-parent =3D <10c00>;
phy-handle =3D <2452000>;
rx-clock =3D <13>;
tx-clock =3D <12>;
};
The driver is working and everything is fine. But as I defined the mac-addre=
ss as 00:e0:ee:00:05:2e
Its constant. Am not able to change this mac -address in linux once the targ=
et is up with LINUX.
How do I change the MAC address. If different targets boards are connected o=
n the network then every board will have the same MAC address as the .dtb f=
ile is the same. How to go about this problem?
It would be a great help if you answer soon.

If different targets boards are connected on the network then every board will have the same MAC address as the .dtb file is the same. 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.

Others have answered your question (the mac address should not be in the
.dts file -- it should be patched in by boot software), but I'd like to
point out that this is a deprecated device tree binding that was very
short-lived in a very old kernel, from an early attempt at 82xx support
in arch/powerpc. Why are you still using it? It will not work with
current kernels (which suggests you're also using a very old kernel).

Hi Wolfgang,

ment variable with the sequence of commands.
And using run command run the environment variable.
But one of the command uses " in the command. So how do I save the command w=
ith quotes.
Below is the command which I want to set in the environment variable.
setenv set_mac ""cp 0xffec0000 0x100000 1024;fdt addr 0x100000 8192;fdt set=

Of course you do, ethaddr has a different syntax and contains :
Anyway you should not have to set mac address manually like you do, u-boot will do it for you if you
have configured u-boot correctly and have a proper dtb tree. Check the u-boot code and the many dts files in linux
under arch/powerpc/boot/dts
For the above command I want to replace the mac address with the ethaddr> How
do I do that. 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.
No additional actions are needed.

Wolfgang Denk

Update, or restrict yourself to using 4 years old Linux kernel

Hi,
I am using 2.6.21 linux kernel with this bootloader.
The ethernet driver in the kernel reads the mac address from the .dtb file.

Hi ,
On my target the date time in linux is not getting updated as per
The NTP server date. The update of date and sync between NTP server and NTP=
client on the target happens
Correctly when the NTP server is made up and then the ntp client is made up.
If I make the NTP server down and then make the NTP client up , then again m=
ake the NTP server up the sync between NTP server
And NTP client on my target fails. The date does not get updated. Could you=
please look the below logs and suggest.
I see that in the not working condition the time reset gets negative value.
