This is the readme for the Das U-Boot standalone program smc91111
The main purpose of this is to manage MAC addresses on platforms
which include the SMC91111 integrated 10/100 MAC Phy, with attached
EEPROMs.
Contents:
------------------------
1. Ensuring U-boot's MAC address can be set in hardware
2. Running the smc91111_eeprom program
3. Setting MAC addresses
4. Other things you can do with this
5. Things to be done.
1. Ensuring U-boot's MAC address can be set in hardware
--------------------------------------------------------------------------
On the Internet - MAC addresses are very important. Short for Media
Access Control address, a hardware address that uniquely identifies
each node of a network. When things are not unique - bad things
can happen. This is why U-Boot makes it difficult to change MAC
addresses.
To find out who has a MAC address, or to purchase MAC addresses, goto
the IEEE, at:
http://standards.ieee.org/regauth/oui/index.shtml
To change your MAC address, there can not be a MAC address predefined in
U-Boot. To ensure that this does not occur, check your
include/configs/<board_name>.h file, and check to see that the following
settings are _not_ or commented out there.
#define HARDCODE_MAC 1
#define CONFIG_ETHADDR 02:80:ad:20:31:b8
The purpose of HARDCODE_MAC is to hardcode the MAC address in software,
(not what we want), or to preset it to 02:80:ad:20:31:b8 (not what we
want either).
You can check this in a running U-Boot, by doing a power cycle, then
before U-Boot tries to do any networking, running the 'printenv' command
BOOT> printenv
ethaddr=02:80:ad:20:31:b8
If you see the 'ethaddr' variable show up, like the above, you need to
recompile U-Boot, with the above settings commented out of the
include/configs/<board_name>.h file.
2. Running the smc91111_eeprom program
---------------------------------------------------------------------
After Uboot is compiled, there should be three files of interest:
-rwxr-xr-x 1 8806 2004-10-11 14:00 smc91111_eeprom <- ELF
-rwxr-xr-x 1 3440 2004-10-11 14:00 smc91111_eeprom.bin <- BIN
-rwxr-xr-x 1 9524 2004-10-11 14:00 smc91111_eeprom.srec <- SREC
if there is not, check the examples/Makefile, and ensure there is something
like for your architecture:
ifeq ($(ARCH),blackfin)
SREC += smc91111_eeprom.srec
BIN += smc91111_eeprom.bin smc91111_eeprom
endif
To load the files: there are two methods: a) serial or b) network. Since
it is not a good idea to start doing things on the network before the
MAC address is set, this example will do things over serial.
a) Loading the elf file via the serial port
--------------------------------------------
Loading the elf is very easy - just ensure that the location
you specify things to load as is not the load address specified
in the Makefile.
BOOT> loadb 0x1000000
## Ready for binary (kermit) download to 0x01000000 at 57600 bps...
(type CNTL-\ then C)
(Back at local machine)
----------------------------------------------------
Kermit>send ~/u-boot_1.1.1/examples/smc91111_eeprom
Kermit>connect
Connecting to /dev/ttyS0, speed 57600
Escape character: Ctrl-\ (ASCII 28, FS): enabled
Type the escape character followed by C to get back,
or followed by ? to see other options.
----------------------------------------------------
## Total Size = 0x00002266 = 8806 Bytes
## Start Addr = 0x01000000
BOOT> bootelf 0x1000000
Loading .text @ 0x00001000 (3440 bytes)
## Starting application at 0x000010d8 ...
SMC91111>
b) Loading the binary file via the serial port
-----------------------------------------------
For many toolchains, the entry point is not the load point.
The Load point is a hard coded address from the
examples/Makefile. The entry point can be found by doing something
like:
u-boot_1.1.1/examples> bfin-elf-objdump -d smc91111_eeprom |less
smc91111_eeprom: file format elf32-bfin
Disassembly of section .text:
00001000 <smc91111_eeprom-0xd8>:
1000:
000010d8 <smc91111_eeprom>:
You can see that the entry point (or the address that should be
jumped to is 0x10d8). This is also the same as the entry point
of the elf file.
Now we load it to the actual load location:
BOOT> loadb 0x1000
## Ready for binary (kermit) download to 0x00001000 at 57600 bps...
(Back at pinky.dsl-only.net)
----------------------------------------------------
Kermit>send /tftpboot/eeprom.bin
Kermit>connect
Connecting to /dev/ttyS0, speed 57600
Escape character: Ctrl-\ (ASCII 28, FS): enabled
Type the escape character followed by C to get back,
or followed by ? to see other options.
----------------------------------------------------
## Total Size = 0x00000d70 = 3440 Bytes
## Start Addr = 0x00001000
BOOT> go 0x10D8
## Starting application at 0x000010D8 ...
SMC91111>
3. Setting MAC addresses
--------------------------------------------------------------------------
The MAC address can be stored in four locations:
-Boot environmental variable in Flash <- can not change, without
re-flashing U-boot.
U-Boot environental variable <- can not change, without
resetting board/U-Boot
LAN91C111 Registers <- volitle
LAN91C111 EEPROM <- Non Volitle
If you have not activated the network, and do not have a hardcoded
or pre-assigned MAC address in U-boot, the environmental variables
should be blank, and allow you to set things one time.
To set the EEPROM MAC address to 12:34:56:78:9A:BC
SMC91111> W E 20 3412
Writing EEPROM register 20 with 3412
SMC91111> W E 21 7856
Writing EEPROM register 21 with 7856
SMC91111> W E 22 BC9A

4. Other things that you can do
--------------------------------------------------------------------------
After the stand alone application is running, there are a few options:
- P : Print the MAC
- D : Dump the LAN91C111 EEPROM contents
- M : Dump the LAN91C111 MAC contents
- C : Copies the MAC address from the EEPROM to the LAN91C111
- W : Write a register in the EEPROM or in the MAC
