Dawood,

The Ethernet Forum has a focus on stand alone Ethernet Phy and MacPhy devices.  I moved your post to the DM3x DaVinci Video Processor Forum so that it can get the visibility it needs.

Hi,

Are you using EVM board or custom board?

If it is custom board , plz check your h/w connections (reset pins ),

If it is EVM board, what is the u-boot config file used to build?

Is this your own build-ed u-boot binary or pre-built binary?

refer the below link

http://e2e.ti.com/support/embedded/linux/f/354/p/314038/1092981.aspx#1092981

Dear Titus

Thanks for your response. I am using LNCQ112IMX136 Leopard Camera which is using TI DM368 platform.

https://www.leopardimaging.com/LNCQ112IMX136.html#0

I have prepared a compiled image of RidgeRun Linux and moved the image file into the SD Card. Then, I configured the board (by setting DIPSWITCH) to boot from SD card. The image can be loaded successfully and I can login into the RidgeRun Linux through Serial Console, but I can't have an Ethernet connection! Although the ethernet interface has been detected by RidgeRun Linux (after boot process) and I can see and even set IP address for it (eth0), it is not able to send or receive packets!!!

I didn't build any u-boot config. Indeed, I just followed all instructions that is provided in below link that it should be a per-build binary file:

https://developer.ridgerun.com/wiki/index.php/Getting_Started_Guide_for_DM368_DM365_LeopardBoard

Also, I didn't find anything special in device manual to enable ETH port through hardware pin.

Please let me know if you have any experience on this subject.

Thanks.

Regards,

Dawood

Hi Dawood,

Can you please provide your complete bootup logs from u-boot to kernel login shell?

Although the ethernet interface has been detected by RidgeRun Linux (after boot process) and I can see and even set IP address for it (eth0), it is not able to send or receive packets!!!

You meant that you cant ping your host Ip addr from ur board!

Plz share  your board file from linux source, we can start to dig into linux source first

What about your make of Ethernet PHY & h/w ?

linux-source/arch/arm/mach-davinci/board-dm368-leobard-camera.c

board-dm368-leobard-camera.c ---> this name may change & check for which appropriate .o file has been created

Dear Titus

Thanks for your response. You may find boot log information of the board within the below lines:

As you can see, eth0 interface is detected and I can assign IP address to it, but it is not able to ping the gateway or any other IP address in the same subnet! I checked the ethernet cable and port with other devices (PC) and it is fine, but I can't figure out why the Camera board (DM368) is not able to communicate with other ethernet devices!

Regarding the existence of board-dm368-leopard.c file, I have a file with this name under the path that you mentioned. May I know what element should be checked inside this file? The full path of the file is:

#/opt/RidgeRun-SDK-DM36x-Turrialba-Eval/kernel/linux-2.6.32.17-psp03.01.01.39/arch/arm/mach-davinci/board-dm368-leopard.c

Also, I checked the existence of Object file (board-dm368-leopard.o) and it has been created already in the following path:

#/opt/RidgeRun-SDK-DM36x-Turrialba-Eval/kernel/linux-2.6.32.17-psp03.01.01.39/arch/arm/mach-davinci/board-dm368-leopard.o

I hope this information can help you to guide me for finding a solution for my problem?

At the end of the day, I need to capture video and images through this camera/SDK and transfer the captured information through Ethernet to other devices.

Regards,

Dawood

Hi Dawood,

Please enable appropriate "EMAC" , "MDIO" and MII or RMII driver in your board file,

I think that you missed ethernet initialization in your board file.

Just do code walk through board-da850-evm.c board file for enabling EMAC, MDIO & MII | RMII  for ethernet

Understand and enable in your leobard board file as per your h/w.

Hi Dawood,

What about your make of MAKE of Ethernet PHY & Hardware Chip ?

Please apply below patch in your board file to enable MDIO for ethernet.

DM36x MDIO configuration

The first problem encountered was the kernel board file wasn't properly telling Linux about the PHY being used.

The following was added to the arch/arm/mach-davinci/board-*.c

/* PHY_MASK indicates to the davinci_emac driver which MDIO addresses
 * to scan for PHY's.  Whatever bits are 1 in this mask are the addresses that
 * that davinci_emac driver will look for a PHY. */
#define DM36x_PHY_MASK    (0x1)
#define DM36x_MDIO_FREQUENCY  (2200000) /* PHY bus frequency */

....

static void dm368_emac_configure(void)
{
        struct davinci_soc_info *soc_info = &davinci_soc_info;

        /* Specify the set of possibly populated  phy addresses */
        soc_info->emac_pdata->phy_mask = DM36x_PHY_MASK;
        soc_info->emac_pdata->mdio_max_freq = DM36x__MDIO_FREQUENCY;

refer this link & let me know the status,

https://developer.ridgerun.com/wiki/index.php/DM368_DM365_Ethernet_cable_plug_unplug

By seeing the below message from MII driver that you have enabled driver but not board init, so apply the above patch,

emac-mii: probed


After that ,Check the clock signals of EMAC from h/w,

Clocks: disable unused emac

Dear Titus

Regarding your instructions, I have appended the following lines (blue lines) within the board-dm368-leopard.c file which is located in the below path:

/opt/RidgeRun-SDK-DM36x-Turrialba-Eval/kernel/linux-2.6.32.17-psp03.01.01.39/arch/arm/mach-davinci/board-dm368-leopard.c

#define DM365_EVM_PHY_MASK              (0x1)
#define DM365_EVM_MDIO_FREQUENCY        (2200000) /* PHY bus frequency */

static void dm368leopard_emac_configure(void)
{
        /*
         * EMAC pins are multiplexed with GPIO and UART
         * Further details are available at the DM368 ARM
         * Subsystem Users Guide(sprufg5.pdf) pages 125 - 127
         */
        //-------------Added by Dawood at 4 Feb 2014-----------------
        struct davinci_soc_info *soc_info = &davinci_soc_info;
        /* Specify the set of possibly populated  phy addresses */
        soc_info->emac_pdata->phy_mask = DM365_EVM_PHY_MASK;
        soc_info->emac_pdata->mdio_max_freq = DM365_EVM_MDIO_FREQUENCY;
        //----------------------------------------------------------------------------

After adding the above lines into the board-dm368-leopard.c file, I executed make & make install commands and then I copied the new generated sd-image file into the SD Card. After booting the board from new generated image (from SD Card), still I can't communicate with other network devices through Ethernet port. Also, I checked Ethernet cable status through /sys/class/net/eth0/carrier file, but there is no change in this file when I unplug the Ethernet cable!!!

Is there anything else that I can do? I am not sure about the file. I chose board-dm368-leopard.c based on my board model (DM368). Please let me know if you get any clue.

Regards,

Dawood

Hi Dawood,

Can you please share your board file from this location "/opt/RidgeRun-SDK-DM36x-Turrialba-Eval/kernel/linux-2.6.32.17-psp03.01.01.39/arch/arm/mach-davinci/board-dm368-leopard.c" ?

I ll do this for you.

It is easy to me to find where is the problem exactly, then you can find difference between your file & modified one,

share your previous bootup log (which is modified for MDIO)

Try to probe the hardware ethernet clock pin. (I think its not required because it is EVM board right!)

Dear Titus

Thanks for your help. You may find the board-dm368-leopard.c file in the following lines. It is the file that I modified based on your comments (I have specified my comments within the file).

Hi Dawood,

Please check your schematics and tell me

What is your make of MAKE/vendor of Ethernet PHY & Hardware Chip ? (like SMSC PHY or anyother PHY h/w !)

to check whether you enabled PHY linux driver (ex: SMSC PHY) or not. plz refer screen shot.

linux-sourec# make menuconfig ARCH=arm

  │ │                                   Device Drivers  --->                                                                             │ │

  │ │                               -*-   PHY Device support and infrastructure  --->                                                    │ │  
and then select appropriate PHY driver

I checked your board file, it everything looks good.

1) Probe the ethernet clock pin to check the frequency.

2) Change  #define DM365_EVM_PHY_MASK        (0x1) to #define DM365_EVM_PHY_MASK        (0x2)

3)Use the attached board file & tell me what is the value of PINMUX3 reg.

4) EVM board (bought simply) or your modified custom board? still im not getting

5)If still this issue is not cleared , then surely it is a hardware problem (because the ethernet problem exists in u-boot   Net:   No ETH PHY detected!!!  ) , 

check connection between MDCLK and PHY chip then MDIO and PHY chip.

Dear Titus

Thanks for your response and sorry for my late reply.

1) Where and how can I probe the ethernet clock pin to check the frequency?

2) I changed 0x1 to 0x2 based on your comment (it is the default value that after using the generated image by using this value still I can't use my ethernet port of the board!)

3) I replaced the attached file (6740.board_2D00_dm368_2D00_leopard.c) with board-dm368-leopard.c file and then rerun the whole compiling procedure. After placing the new sdcard.img file into the SD memory and booting the board with it, still the problem exists! BTW, could you please let me know how can I check PINMUX3 reg? There is no such a value in board-dm365-evm.c file.

4) As I mentioned you already, I am using Leopard camera LNCQ112IMX136 board that you may find its data sheet in the following link.

https://www.leopardimaging.com/uploads/IPCAM_Userguide.pdf

Also, I took some photos from the camera board that is based on DM368 and you can find them in the below link:

https://www.dropbox.com/sh/cvf5i3h8jfwzkm5/6kciro1fwc

5) How can I check the connection between MDCLK & PHY chip or MDIO & PHY chip?

Thanks for your attention.

Regards,

Dawood

Hi,

1) If you use my previous attached reply's file, then you could see

    printk("Updated PINMUX3 reg value for EMAC = %x\n",temp);

2) 3)Use the previously attached board file & attach/share your bootup logs

How can I check the connection between MDCLK & PHY chip or MDIO & PHY chip?

Where and how can I probe the ethernet clock pin to check the frequency?

Check with your hardware engineer for this

or

Find in Internet & Share your board schematics to check.

Dear Titus

I have tried to compile and run the file that you had attached in your prior posts but I got a lot of error messages! It seems something is wrong with the file (6740.board_2D00_dm368_2D00_leopard.c). Hence, I can't get PINMUX3 reg value. You may see the error messages in the following lines:

Regarding the "connection between MDCLK & PHY chip or MDIO & PHY chip & probing the clock pin", with all respect, but your answer doesn't ring a bell for me! What a hardware engineer is supposed to do while I have passed all necessary information about the board model, datasheet and even taken photos to you already? I should not be the first guy on the Earth that has encountered Ethernet problem in a RidgeRun Linux on Leaprd boards that are using TI chips (DM368)...

As a TI employee, if still you are interested to help me for addressing the existing issue, please give me detailed and more practical hints. Thanks for your time and attention.

Hi,

root@RidgeRunSDK:/opt/RidgeRun-SDK-DM36x-Turrialba-Eval/kernel/linux-2.6.32.17-psp03.01.01.39/include# gcc 6740.board_2D00_dm368_2D00_leopard.c

Why are you building linux kernel by gcc and not cross compiler?

Linux kernel Building:

host-linux $ make uImage ARCH=arm CROSS_COMPILE=<tool chain>

Ex:

make clean ARCH=arm CROSS_COMPILE=arm-arago-linux-gnueabi-   (cleaning old compiled obj files)

make distclean ARCH=arm CROSS_COMPILE=arm-arago-linux-gnueabi-  (cleaning old config files)

make davinci_dm365_leobard_defconfig ARCH=arm CROSS_COMPILE=arm-arago-linux-gnueabi-  (located under arch/arm/configs/ < ur board def config)

make uImage ARCH=arm CROSS_COMPILE=arm-arago-linux-gnueabi- (building linux kerne uImage)

Please replace the attached file in arch/arm/mach-davicni/ from previous reply (6740.board-dm368-leopard.c)

#/opt/RidgeRun-SDK-DM36x-Turrialba-Eval/kernel/linux-2.6.32.17-psp03.01.01.39/arch/arm/mach-davinci/board-dm368-leopard.c

#/opt/RidgeRun-SDK-DM36x-Turrialba-Eval/kernel/linux-2.6.32.17-psp03.01.01.39/ # make uImage ARCH=arm CROSS_COMPILE=arm-arago-linux-gnueabi-

and tell me what is the PINMUX3 value printed at bootup log?

"    printk("Updated PINMUX3 reg value for EMAC = %x\n",temp);  "

Dear Titus

Thanks for your kind response. I followed your instructions and the PINMUX3 value in new bootlog is:

--------------------------------

DaVinci: 8 gpio irqs
NET: Registered protocol family 16
davinci_serial_init:97: failed to get UART2 clock
Updated PINMUX3 reg value for EMAC = 815affff
bio: create slab <bio-0> at 0
DM365 IPIPE initialized in Single Shot mode
SCSI subsystem initialized
-------------------------------

Also, after booting the system, when I run the ifconfig command no Ethernet port is detected:

/ # ifconfig
lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Mask:255.0.0.0

          collisions:0 txqueuelen:0
          RX bytes:504 (504.0 B)  TX bytes:504 (504.0 B)

After manual enabling Ethernet port with ifconfig, I encountered an error that is shown in the below lines:

Save all the modified configurations in kernel and build uImage & boot the board,

Share me the full bootup logs.

Dear Titus

I followed your instructions and loaded the new image file within the SD Card and booted the camera board through it. After logging in, still I can't enable Ethernet interface by using ifconfig command. You may find the boot log messages in the following lines. In the last lines, I tried to enable Ethernet port, but it was not successful.

If not fixed,

2) Undo the old fix which is used from the following link previously,

As of now, These are the trial and error methods to narrow down your issues.

Dear Titus

Thanks for your comment. I replaced your file with former file that you sent me and then I built the new image file. After flashing the image file into the SD Card and booting the board, still the problem exists! (I received an error when I tried to enable eth0 as same as that shown in my previous post)

BTW, in my Ubuntu Linux that I used it to build image file, I don't have any cross compiler under arm-arago-linux-gnueabi-*  name!  As I mentioned you already, I followed the presented instruction within the below link:

https://developer.ridgerun.com/wiki/index.php/Getting_Started_Guide_for_DM368_DM365_LeopardBoard

It seems by following these instructions, all environmental variables and default value of cross-compiler will be set automatically. Hence I just run make config and then make and make install commands. By execution of these commands a new image file will be created under ../image folder.

Regards,

Dawood
