How To Set OMAPL138 Ethernet Mac Address?

Other Parts Discussed in Thread: OMAPL138, OMAP-L138, DA8XX, PMP

Hi,

Hoe can set OMAPL138 ethernet mac address to be fixed for all next boot ? [...because now the mac address change every boot? ]

During boot process i recieve this messages:

    The MAC address must be written to the SPI slash at 07f0000 (the last 64k), in binary.


    You can do this from u-boot, or from the shell prompt if you have the MTD devices enabled in the kernel, e.g.

    flash_eraseall /dev/mtd3

    echo -n '\xXX\xXX\xXX\xXX\xXX\xXX' > /dev/mtd3


    (the 'XX' being your MAC address from the sticker)

    Hi,

    Refer this link http://processors.wiki.ti.com/index.php/GSG:_OMAP-L138_DVEVM_Additional_Procedures#Restoring_MAC_address_on_SPI_Flash

    for setting the MAC address at U-boot prompt.

    Hi,

    I was try to do what  you wrote and i was not success.

    First, this is results of  "ls /dev" command:

    ptyp5 tty41 vcsa2
    ptyp6 tty42 watchdog

    ptyp7 tty43 zero
    ram0 tty44
    random tty45

    Second, this is result of  "cat /proc/mtd" command:

    root@arago:~# cat /proc/mtd

    dev: size erasesize name

    mtd3: 00010000 00010000 "MAC Address"

    Now, when i try to operate  "flash_eraseall /dev/mtd3" command, i recieve that message:

    root@arago:~# flash_eraseall /dev/mtd3
    flash_eraseall: /dev/mtd3: Permission denied

    When i try to operate  "echo -n '\xXX\xXX\xXX\xXX\xXX\xXX' > /dev/mtd3" command, i recieve that message:

    root@arago:~# echo -n '\xXX\xXX\xXX\xXX\xXX\xXX' > /dev/mtd3
    -sh: can't create /dev/mtd3: Permission denied

    When i operate  "flash_eraseall /dev/mtd3" command from u-boot , i recieve that message:

    But this Mac Address is not save in  memory and when i boot OMAP i still recieve invalid Mac Address.

    So what is the problem?

    What i can do to solve this problem and make my Mac Address to be fix?

    Thanks, Oded.

    Hi,

    Please perform following steps,

    1:Modify the DDR content at address c0000000. MAC address is printed on a sticker pasted on SoC module of EVM.

    U-Boot> mm.b c0000000
c0000000: fb ? 00
c0000001: ef ? 08
c0000002: fd ? ee
c0000003: df ? 03
c0000004: ff ? 6a
c0000005: ff ? c4
c0000006: bf ? q

    2:Make sure that modification is correct:

    U-Boot> md.b c0000000
c0000000: 00 08 ee 03 6a c4 bf ff f3 fd fb ff fe fd bf ef    ....j...........
c0000010: ff ff fb fd 3f fd ff ff bb df 7f fd f7 ff 77 ff    ....?.........w.
c0000020: 7f ee f7 fd 3f fd fb fd ed ef bf ce 77 bf fb ff    ....?.......w...
c0000030: 6f bc b7 fe ff de fd ff 7b fd ff ff b7 fd ff ff    o.......{.......

    3: Initialize SPI flash from u-boot.

    U-Boot> sf probe 0

    4: Write the MAC address from DDR to SPI flash:

    U-Boot> sf write c0000000 7f0000 6

    5: Reset the EVM. U-Boot/Kernel should read the MAC address which was written to the flash.

    Thx,

    In order from the "user mode" change to work, your kernel needs to allow "write" access to the MTD device. This requires patching the partition table in the kernel. The "flash_eraseall" command is part of busybox (i'm using 1.18.5) and you'll need to menuconfig that applet into it.

    I guess it's easier to use the u-boot method in your case, since you'll only need to do this once.

    Looks like, you are trying this in other boot mode ie. not SPI boot mode rite ?

    You need to use uboot which is build enabling CONFIG_USE_SPI and flash it in

    SPI. The above commands which you tried are SPI commands, flashing a SPI enabled image 

    should solve your issue.

    Hi,

    I am struggling with the same problem on the TI OMAPL138 LCDK.

    This board uses NAND instead of SPI FLASH in uboot. I am wondering how I can change the 'ethaddr' environment variable. EVERY LCDK board we have boots with:

    ethact=DaVinci-EMAC
    ethaddr=00:00:a0:00:fb:c7

    I tried setting it:

    U-Boot > setenv ethaddr 08:00:28:32:51:27
Can't overwrite "ethaddr"
U-Boot > env set ethaddr 08:00:28:32:51:27
Can't overwrite "ethaddr"
U-Boot > env set -f ethaddr 08:00:28:32:51:27
U-Boot > env print ethaddr
ethaddr=00:00:a0:00:fb:c7

    Of course I do not have the sf probe commands as I am using NAND, I have nand read and nand write however I do not know at what address the drivers are reading the mac

    '08:00:28:32:51:27'

    From. 

    Thanks

    I also found this which concerned me:

    static int get_mac_addr(u8 *addr)
    {
    /* Need to find a way to get MAC ADDRESS */
    return 0;
    }

    Hi Evan,

    You can change the MAC address.
    Have you changed the u-boot board config file (*.h) ?

    common/cmd_nvedit.c
    Try to use/append the following config in u-boot board file.

    include/configs/omapl138_lcdk.h

    #define CONFIG_ENV_OVERWRITE
