--- ping statistics ---
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?

are using the board MPC8313ERDB and we are facing problems regarding
u-boot environment variables(the environment variables displayed after
giving &#39;printenv&#39; command at u-boot prompt).<br><br>We are following the steps stated as below:<br><br>1. =&gt;printenv<br><br>output is:<br>....<br>....<br>bootargs=root=/dev/mtdblock2 rootfstype=jffs2 rw console=ttyS0,115200<br>

output:<br>Saving Environment to Flash...<br>Un-Protected 1 sectors<br>Erasing
 Flash...<br>. done<br>Erased 1 sectors<br>Writing to Flash... done<br>Protected 1 sectors<br><br>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, <br><br>4. =&gt;printenv<br><br>ileaddr=200000<br>
ipaddr=<a href="" target="_blank"></a><br>

ethact=TSEC0</span><br style="background-color: rgb(255, 255, 0);">
<br>Here again the value of ethact is changed to TSEC0.<br><br>we have following questions:<br><br><span style="font-weight: bold; text-decoration: underline; font-style: italic;">question 1</span>: We want to know the reason why it(ethact variable) changes to TSEC0 everytime with a reset.<br>

<br><span style="font-weight: bold; text-decoration: underline; font-style: italic;">question2</span><span style="text-decoration: underline; font-style: italic;">:</span>
After we have set ethact to TSEC1 and saved it(=&gt;saveenv) and tried
to ping the Host from u-boot prompt it is working (displaying: &#39;host
alive&#39;).<br>But when we are trying to ping Target board from the host it is showing:<br><br>PING <a href="" target="_blank"></a> (<a href="" target="_blank"></a>) 56(84) bytes of data.<br>
