Guys regarding the second i.e. network issue i digged that <br>
<br>
/* if MAC address was not discovered yet, save the packet and do an ARP request */<br>
if (memcmp(ether, NetEtherNullAddr, 6) == 0) {<br>
is returning true and actually its sending ARP packets for address discovery. I suppose i have some misconfiguration.<br>
<br>
I shall investigate this and update tomorrow.<br>
<br>
Sorry if this is off-topic for either of the lists.<br>
<br>
cheers,<br>

<div style="direction: ltr;">Hi,<br>
<br>
Skyeye wiki shows howto load u-boot on the pc emulator. I have been
trying to do the same for the at91rm9200 board on my pc but am getting
no success. I am therefore sending this mail to both the
skyeye-developers and u-boot-users list. I would appreciate if you
could suggest some inputs as this is my very first hands on with both
the (should i say?) applications.<br>
<br>
Input/output is ignored at the boot prompt for the at91rm9200 board<br>
(1) I have had success loading u-boot for ep7312 board via skyeeye
emulator while the u-boot for at91rm9200 simply doesn't takes any key
strokes whatsoever at the boot prompt. <br>
<br>
The only difference between the two u-boot config files is that the
following three lines are not present in ep7312 board config. As am on
emulation mode i have set USART0 instead of DBGU for the at91rm9200
board<br>
<br>
#undef CONFIG_DBGU<br>
#define CONFIG_USART0<br>
#undef CONFIG_USART1<br>
<br>
When i run the skyeye with this config i get the following <br>
In: serial<br>
Out: serial<br>
Err: serial<br>
U-Boot> <br>
(I get the same message for ep7312 board but the input is actually /dev/stdin and output/err is /dev/stdout)<br>
<br>
The keystrokes are simply ignored at the boot prompt. I tried the followoing skyeye configuration<br>
uart: fd_in=/dev/stdin, fd_out=/dev/stdout so atleast i could redirect
the serial input output via stdin/stdout. But this didn't help me
either.<br>
<br>
This is really annoying as i can see the skyeye emulator working but am unable to how to redirect the input/output. Any guesses?<br>
<br>
<br>
Networking issue with ep7312 u-boot.bin and skyeye<br>
(2) the u-boot for ep7312 board which loads fine has the following configuration<br>
#define CONFIG_ETHADDR 0:4:3:2:1:f<br>
#define CONFIG_NETMASK <a href="http://255.0.0.0" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">255.0.0.0</a><br>
#define CONFIG_IPADDR <a href="http://10.0.0.2" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">10.0.0.2</a><br>
#define CONFIG_GATEWAYIP <a href="http://10.0.0.1" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">10.0.0.1</a><br>
#define CONFIG_SERVERIP <a href="http://10.203.234.11" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">10.203.234.11</a><br>
<br>
and skyeye.conf defines<br>
net: state=on, type=vnet,base=0xfffa0000, size=0x20,int=16, mac=0:4:3:2:2:f, ethmod=tuntap, hostip=<a href="http://10.0.0.1" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">10.0.0.1</a><br>
<br>
When i run the skyeye emulator, u-boot boots fine and shows me the
prompt. I could see a new virtual network interface present and can
ping the new virtual host as well. But, when i do a tftpboot the boot
prompt simply hangs. The tftp logs doesn't shows any file request either<br>
