[Raghu]

Dear All,

I am observig this on u-boot 0.3.0 I have a the
following setup

MPC8245 based board with Intel 82559ER ethernet
controller.

I am using the "tftpload" command to load a file from
the tftpserver. But if I type a wrong filename its
reports a TFTP_ERROR as "File not Found". 

And for the very next "tftpload" command with a
correct file name it make ARP broadcast and loads the
file only after the 5 th retry. 

I am attaching the sequence of comands I am running. 
Is this a feature or a bug :-) ??

Are you on a switch or a hub?

If you are on a switch it is possible for the switch to take some
time to "learn" your MAC address if you have spanning tree activated.

If you have access to the switch disable the spanning tree algorithm.

Do you have CONFIG_NET_MULTI defined in your board config file?
If yes, disable it, and try again.

HI, 

Yes, I had the  CONFIG_NET_MULTI define. 

Now I have modified to, 

#undef CONFIG_NET_MULTI
#define CONFIG_EEPRO100         1
#define CONFIG_COMMANDS   (   CONFIG_CMD_DFL  | \
                              CFG_CMD_FLASH   | \
                              CFG_CMD_SDRAM   | \
                              CFG_CMD_ENV     | \
                              CFG_CMD_PCI     | \
                              CFG_CMD_NET )

But undefining this breaking the build. 

I get the following unresolved errors. 

/home/raghu/u-boot-0.3.0/net/net.c:149: undefined
reference to `eth_halt'
/home/raghu/u-boot-0.3.0/net/net.c:150: undefined
reference to `eth_init'
/home/raghu/u-boot-0.3.0/net/net.c:252: undefined
reference to `eth_rx'
/home/raghu/u-boot-0.3.0/net/net.c:294: undefined
reference to `eth_halt'
/home/raghu/u-boot-0.3.0/net/net.c:258: undefined
reference to `eth_halt'
net/libnet.a(net.o): In function `NetSendPacket':
/home/raghu/u-boot-0.3.0/net/net.c:376: undefined
reference to `eth_send'

These functions in net/etc.c file are defined under
the macro, 
#if (CONFIG_COMMANDS & CFG_CMD_NET)  &&
defined(CONFIG_NET_MULTI)

Warm regards,
Raghu.
