[U-Boot-Users] 4xx ethernet bringup

[shami Allam]

Hi All,

I am working on the 405GP custome board. I am able to bringup the SDRAM,Flash,I2c and serail on the board. But while trying to bringup the ethernet i am getting the following error.
"No Ethernet found". On my board there is "DP83848I" PHY chip. 

what exactely this is doing in lib_ppc/boarc.c 
s = getenv ("ethaddr");
#if defined (CONFIG_MBX) || \
defined (CONFIG_RPXCLASSIC) || \
defined(CONFIG_IAD210) || \
defined(CONFIG_V38B)
if (s == NULL)
board_get_enetaddr (bd->bi_enetaddr);
else
#endif
for (i = 0; i < 6; ++i) {
bd->bi_enetaddr[i] = s ? simple_strtoul (s, &e, 16) : 0;
if (s)
s = (*e) ? e + 1 : e;
}
#ifdef CONFIG_HERMES
if ((gd->board_type >> 16) == 2)
bd->bi_ethspeed = gd->board_type & 0xFFFF;
else
bd->bi_ethspeed = 0xFFFF;
#endif

and in the same file there is one more call...
#if (CONFIG_COMMANDS & CFG_CMD_NET)
#if defined(CONFIG_NET_MULTI)
WATCHDOG_RESET ();
puts ("Net: ");
#endif
eth_initialize (bd);
#endif

In the eth_initialize() function i see the print "No ethernet found". i reqeust you to please throw some out to come out of this problem......**********EXIT ME PLZ*************

Thanks
Shami.

This message gets printed when you don't define the "ethaddr" environement 
address. So set this variable to a valid value and save the environment and 
reset the board. Then you should see one eth-interface.

Hi Stefan,
   
  I assigned the ethaddr as 192.168.13.246 and after that i run the command "saveenv " and reset the board. I got the following
Net: ppc_4xx_eth0. once i get the shell prompt i assign the ipaddr as 192.168.13.241 and after that i run the command "saveenv" and reset the board. Now i tried to ping my Host PC which has the IP address as 192.168.13.240, i am getting the following error.....I am not able to ping the host IP. Can you please show some way to come of this issue.....

That looks like an IP address to me.

A MAC address is something different. Please see
http://en.wikipedia.org/wiki/MAC_address

Also make sure to read the FAQ.

[U-Boot-Users] Boot 440EPx from NAND

[Leonid]

Hi:

I am trying to boot 440EPx board similar to Seqouia from NAND. NAND
flash is different from Sequoia's though, it has page size 2K, sector
size 128K and it's 1Gb (128MB).

I set following parameters in my <board>.h file:

#define CFG_NAND_U_BOOT_SIZE	(600 << 10)	/* Size of RAM U-Boot
image	*/

/*
 * Now the NAND chip has to be defined (no autodetection used!)
 */
#define CFG_NAND_PAGE_SIZE	(2048)		/* NAND chip page size
*/
#define CFG_NAND_BLOCK_SIZE	(128 << 10)	/* NAND chip block size
*/
#define CFG_NAND_PAGE_COUNT	(64)		/* NAND chip page count
*/
#define CFG_NAND_BAD_BLOCK_POS	(5)		/* Location of bad block
marker	*/
#define CFG_NAND_4_ADDR_CYCLE			/* Fourth addr used
(>32MB)	*/

but it doesn't boot.

Any suggestion? What is CFG_NAND_PAGE_COUNT anyway?

Thanks,

Leonid.

As Wolfgang already mentioned, this is *not* an ethernet address but an IP 
address.

Did you configure the PHY address correctly? What does "mii info" show? how 
did you configure the PHY address in your board config file?

The current code is tested only for 512byte page size NAND devices. Very 
likely it needs some changes for 2k devices. Especially the ECC stuff will 
need some changes.

> What is CFG_NAND_PAGE_COUNT anyway? 

CFG_NAND_PAGE_SIZE defines the number of pages per block. For example a 
64MByte NAND chips has a page size of 512 bytes and a block size of 16kbytes. 
This makes 16k/512 == 32.

Stefan

[Leonid] You mean 512 bytes block may be hardcoded somewhere instead of
using page size definition from <board>.h file? Any suggestions what
places in the code look into? ECC stuff - where is it?

[Leonid] OK, that what I thought it is. In my flash with 128K blocks and
2K pages I got page count 128/2=64.

Thanks a lot,
Leonid.

Thanks for the information. But I read some where that for the Lab testing purpose that I can give the IP address!!!!!
  I am able to read the PHY inforamtion by command mii info 0x01<PHY Addr>. Following is the info....
=> mii info 0x01
PHY_PHYIDR2 @ 0x1 = 0x5c90
PHY_PHYIDR[1,2] @ 0x1 = 0x20005c90
PHY_BMCR value is 0x2100
PHY 0x01: OUI = 0x80017, Model = 0x09, Rev = 0x00, 100baseT, FDX
=>
  But my Link LED is not glowing at all. Always my Link status shows "Not Active" can anyone throw some light for me.....

Please don't mix up ethernet address (== MAC address) and IP address. Of 
course you can set ip addresses (and should if you don't use dhcp/bootp). But 
you have to configure valid ethernet addresses too. If you don't have an 
ethernet address pool, you can use the "tools/gen_eth_addr" tool to create a 
random valid eth address for testing.

And what does "mii info" show (without parameter)?

What is the value of CONFIG_PHY_ADDR in your board config file?

Please don't mix up ethernet address (== MAC address) and IP address. Of 
course you can set ip addresses (and should if you don't use dhcp/bootp). But 
you have to configure valid ethernet addresses too. If you don't have an

And what does "mii info" show (without parameter)?


 => mii info
 PHY ID register 2 read failed
 PHY_PHYIDR2 @ 0x1 = 0x5c90
 PHY_PHYIDR[1,2] @ 0x1 = 0x20005c90
 PHY_BMCR value is 0x2100
 PHY 0x01: OUI = 0x80017, Model = 0x09, Rev = 0x00, 100baseT,
 PHY ID register 2 read failed
 PHY ID register 2 read failed
 PHY ID register 2 read failed
 PHY ID register 2 read failed
 PHY ID register 2 read failed
like this many....


What is the value of CONFIG_PHY_ADDR in your board config file?

follwing i defined in the board config file.....

#define CONFIG_PHY_ADDR  1

[U-Boot-Users] 4xx ethernet bringup

[shami Allam]

Hi Stefan,

After booting my target i get the following message..
 
 I2C:ready
 DRAM:16MB
 FLASH:2MB
 In: serial
 Out:serial
 Err:serial
 Net: ppc_4xx_eth0
 =>
 and after that if i say
 => mii info
 PHY 0x01: OUI = 0x80017, Model = 0x09, Rev = 0x00, 10baseT, HDX
 => setenv ipaddr 192.168.13.248
 => ping 192.168.13.248
 After this if i ping it's not pinging self and also the host ip(192.168.13.240). Can you help me out what could be the problem.....
 => mii read 0x01<PHY Addr> 0x01<register val>
 when i read the PHY 0x01 register following is the value 0x7849. This value show that "No Link". why so. PHY chip i am using DP83848I

 Regards,
 Shami.

This message gets printed when you don't define the "ethaddr" environement 
address. So set this variable to a valid value and save the environment and 
reset the board. Then you should see one eth-interface.

And is this correct? Do you have a 10MBit connection?

So you try to ping to yourself here. This does not work. You have to ping to a 
different target (PC).

Possibly a PHY configuartion problem. Did you check if you soldered the 
correct resistors and condensators? Is the power-supply ok?

Stefan

  it support both 100baseT and 10baseT.

  Yes i tried to ping the Host PC (i.e) 192.168.13.240. But still i am not getting reply.....

correct resistors and condensators? Is the power-supply ok?
   
  if I do the PHY loopback by enabling the bit 14bit in the BMCR. i am getting the reply. Still you suspect PHY configuration problem.....or do i need to do anything at MAC side......

  Shami.

Yes, I still suspect PHY hardware problems. Check (again) all R's and C's, 
clocks and power supplies.
