   Hi,
   It appears the ping in UBOOT is broken. The ping works fine 
   if you have a
   network connection. But if the network connection is 
   disconnected the ping
   hangs the system. There is no response to Control-C either. I 
   have to power
   cycle the proto to get back to a UBOOT prompt. Is this a 
   known issue or did
   I possibly break something?
   
   I have a board based on the Atmel AT91SAM9RL-EK. My theory is 
   that it may
   be a generic problem with the uboot ping. I can't confirm 
   that since the
   only hardware I have is our protos.
   
   It was noticed on the OMAP3EVM last FRI and we were suspecting
   it to be problem with the omap3 board configuration itself.
   (Though did not spend much time in debug).
   
   Now, I too get a feeling that it could be a generic problem.
   
   Best regards,
   Sanjeev
   
   Does anyone else have a board with another MAC/PHY that you 
   can try this on?
 
 Ideally, if there is no link, the ping command should just exit
 gracefully without attempting network operations.  Eg on my 8561-based
 board with no cables plugged in:
 = ping 192.168.1.1
 Auto-neg error, defaulting to 10BT/HD
 eTSEC1: No link.
 Auto-neg error, defaulting to 10BT/HD
 eTSEC2: No link.
 ping failed; host 192.168.1.1 is not alive
 
 there is no delay in the printing of the above info.
 
 The tsec driver's init function returns -1 when link isn't detected.
 Perhaps your ethernet driver should do the same?
 
 What happens if you ping a non-existent IP address?  Does 
 that also hang
 the board?  Do other network operations hang the board if no ethernet
 cable is plugged in?

Here is a session from OMAP3EVM:

OMAP3_EVM # setenv autoload no
OMAP3_EVM # dhcp
smc911x: initializing
smc911x: detected LAN9115 controller
smc911x: phy initialized
smc911x: MAC 00:50:c2:7e:88:72
BOOTP broadcast 1
BOOTP broadcast 2
DHCP client bound to address 192.168.1.10
OMAP3_EVM # ping 192.168.1.1
smc911x: initializing
smc911x: detected LAN9115 controller
smc911x: phy initialized
smc911x: MAC 00:50:c2:7e:88:72
ping failed; host 192.168.1.1 is not alive
OMAP3_EVM #

 Peter

[U-Boot] potential Uboot Ping problem

2009-06-01 Thread Steven Zedeck 

Hi,

network connection. But if the network connection is disconnected the ping
hangs the system. There is no response to Control-C either. I have to power
cycle the proto to get back to a UBOOT prompt. Is this a known issue or did

I have a board based on the Atmel AT91SAM9RL-EK. My theory is that it may
be a generic problem with the uboot ping. I can't confirm that since the
only hardware I have is our protos.

Does anyone else have a board with another MAC/PHY that you can try this on?

As for UBOOT code, our environment is based on 2008.10 code. Our MAC/PHY is
the Microchip ENC28J60.

Thanks,
Steve

Re: [U-Boot] potential Uboot Ping problem

2009-06-01 Thread Steven Zedeck 

I guess thats good news. I looked inside the cmd_ping code a bit. I bet
there's a while loop somewhere that is waiting for something and may not
have a timeout loop. Any ideas?

Thanks,
Steve

The ethernet driver is also from the uboot distribution. Its enc28j60.c.
I'll need to go through it to see where its hanging assuming its in that
driver or the ping code that calls it.

thanks,
Steve
