12 packets transmitted, 0 received, +9 errors, 100% packet loss, time

, pipe 3

Why is it happening so?

question 3: After we have set 'ethact' to TSEC1, the kernel is loaded,
and we have logged -in, when we try to ping the Host from target it says
'100% packet lost'. also we are unable to ping target from the host. Why
is it happening so?

Awaiting a prompt reply

The environment variable ethact =
does not, &#8220;stick&#8221;
for me either, although it&#8217;s not an issue for me. Look in eth.c to =
learn
when/how it is initialized. Note the CONFIG_NET_MULTI constant (I have =
it
defined, but I&#8217;m not sure why).<o:p></o:p>

I bet you have that defined in =
your board
header file. Take a look and see if you can get your custom ethact to =
stick by defining
or undefining that or something.<o:p></o:p>

We are using the board MPC8313ERDB and we are facing problems =
regarding
u-boot environment variables(the environment variables displayed after =
giving
'printenv' command at u-boot prompt). 
 
We are following the steps stated as below: 
 
1. =3D&gt;printenv 
 
output is: 
.... 
.... 
bootargs=3Droot=3D/dev/mtdblock2 rootfstype=3Djffs2 rw =
console=3DttyS0,115200 
bootcmd=3Dbootm fe100000 - fe700000 
filesize=3D1a4a05 
fileaddr=3D200000 
ipaddr=3D<a href=3D"http://192.168.1.101/" =
target=3D"_blank">192.168.1.101</a> 
serverip=3D<a href=3D"http://192.168.1.57/" =
target=3D"_blank">192.168.1.57</a> 
stdin=3Dserial 
stdout=3Dserial 
stderr=3Dserial 
ethact=3DTSEC0 
 
 
Here ethact is TSEC0 by default. 
 
2. =3D&gt;setenv ethact TSEC1 
3. =3D&gt;saveenv 
output: 
Saving Environment to Flash... 
Un-Protected 1 sectors 
Erasing Flash... 
. done 
Erased 1 sectors 
Writing to Flash... done 
Protected 1 sectors 
 
Here we have set the ethact variable to TSEC1 and saved it. Now it is =
showing
that this value of ethact is burnt in flash. But after the board is =
reset, 
 
4. =3D&gt;printenv 
 
ileaddr=3D200000 
ipaddr=3D<a href=3D"http://192.168.1.101/" =
target=3D"_blank">192.168.1.101</a> 
serverip=3D<a href=3D"http://192.168.1.57/" =
target=3D"_blank">192.168.1.57</a> 
stdin=3Dserial 
stdout=3Dserial 
stderr=3Dserial 
ethact=3DTSEC0 
 
Here again the value of ethact is changed to TSEC0. 
 
we have following questions: 
 
question =
1:
We want to know the reason why it(ethact variable) changes to TSEC0 =
everytime
with a reset. 
 
question2=
: After we have set ethact to =
TSEC1
and saved it(=3D&gt;saveenv) and tried to ping the Host from u-boot =
prompt it is
working (displaying: 'host alive'). 
But when we are trying to ping Target board from the host it is =
showing:
