[U-Boot-Users] ethernet on FCC

[jie han]

Hi,
My mpc8270 board use three ehternet ports at FCC1,FCC2,FCC3.it is 
work well at FCC1.When I use port FCC2, I found out the 
  u-boot is not receiving packets (It's sending correct packet when i
  use ethereal for sniffing). When trying "ping", it generated an ARP
  packet first, the other host replied with , but the board never seems
  to receive it(set printf at function fec_recv()  /cpu/mpc8260/ether_fcc.c ).all three ethernet fcc ports initiailze is same.Do I miss something?thank you for your suggestion,my config file config FCC port parameter as follow:

Hi Jie,

I don't have any good insights, but some things to try:
* Are you sure, positive, double checked and had a co-worker check that 
your clock input for FCC2-Rx is configured properly?
   1) Which CLK input is used?
   2) The port/pin configuration initialization in u-boot?
   3) Your hardware (traces) actually connect the right pins?

* Does FCC3 work?

* If you turn off CONFIG_NET_MULTI and only use FCC2, does it work?

* If you turn off CONFIG_NET_MULTI and only use FCC3, does it work?

Good luck,
gvb

Thank you for your help.The fcc2 working now,It is my mistake to config fcc2 RX_DV port pin.

Sincerely,

Jie

[U-Boot-Users] ethernet on FCC

[Lei Sun]

Hi;
  Please ignore my first question regarding proff_enet, I wasn't too
careful, it was inialized when defining the array.
  But still, can't explain why its not receiving any packets though.

Does it have a valid, unique MAC address?

[U-Boot-Users] ethernet on FCC

[Lei Sun]

Yeah, i suppose so. I connect my host to the board with a hub, give
them static IP, and set the MAC address to be the same as my host's
MAC, except one byte. Then I sniff the packet on my host using
ethereal.
Is the MAC address being compared in CPM's micro code ?

Thanks

Which byte do you change?  Don't touch the left-most one, as its bits
have special meaning.  When you say you 'set the MAC address', how do
you do it?  Does the 'Source Address' field in the ARP packet sent by
your board match the MAC address that you set?

> Is the MAC address being compared in CPM's micro code ?
Unicast addresses are compared to registers in the CPM, which may be
implemented in microcode but that's neither here nor there.

Ben

I changed the last byte (count start from left). I set the MAC via
environment "ethaddr", I've also defined "CONFIG_ETHADDR" so to force
it to fixed value.  My ethereal did show the correct source MAC
address for the broadcast ARP request. The host replied with unicast
ARP reply, that's when my board failed to get it. Haven't tried if my
board could get broadcasted packet yet.

Thanks

Hi:
  While tring to bring up my mpc8270 based board, I found out the
u-boot is not receiving packets (It's sending correct packet when i
use ethereal for sniffing). When trying "ping", it generated an ARP
packet first, the other host replied with , but the board never seems
to receive it.
  When digging into the code, in cpu/mpc8260/ether_fcc.c file, it
tries to initialize the parameter ram by :

pram_ptr = (fcc_enet_t *)&(immr->im_dprambase[info->proff_enet]);

However, I can't seems to find where the info->proff_enet got
initialized. I am using u-boot-1.1.4, but the 1.1.6 code does the same
thing.
  The ether_scc.c file seems doing the right thing, because it defined
PROFF_ENET as a macro.

A bug ?

Another thing, I loaded the uImage into memory using JTAG, but the
"bootm" command failed when it tries to uncompressing the kernel,
error message is "inflate() returned -3". I am running u-boot in ram
directly , not from the flash, I have found some posts which saids if
u-boot is running from RAM, it can't uncompressing the kernel, but
without any explaination on why.

Thanks

Check your memopry map. You might have loaded the kernel (and/or
U-Boot) to a too low address.

No, this is wrong. If you manage to get U-Boot starting from RAM, and
it is working correctly, then  it  can  boot  and  uncompress  kernel
images, too.

[U-Boot-Users] Ethernet On FCC

[Vikrant_Basotra]

Hi all,

We are designing an MPC8260 Board which had an LXT971 Ethernet chip on it.

The ethernet chip is connected to FCC2 port.

1.According to me the Ethernet initialization for FCC is done in the
function "fec_init" in Ether_fcc.c.

  The function "fec_init" is being called in Eth.c/eth_init()

  The function "eth_init" is being called in Net.c/NetLoop().

  The function "NetLoop" is being called in cmd_net.c/netboot_common.

 

  The function "fec_initialize" is being called in eth.c 

  The function "eth_initialize" is being called in board.c

 

I am not able to make out from where fec_init is being called initially?

 

2.Also there is another function "reset_phy" in board.c. Is this the
starting point for Ethernet intialization?

 

Thanks and Regards,

Vikrant.
