one question about dm8148 demo board

Hi Bob,

Welcome to the E2E forum.

bob lee said:

I don't what's wrong with the kerne.

Are you using the DM814x EZSDK 5.05.02.00 or other software?

Are you using the default (pre-built) linux kernel (uImage) or you made some changes?

Have a look also into the below wiki page:

http://processors.wiki.ti.com/index.php/Kernel_-_Common_Problems_Booting_Linux#Problem_.232_-_No_more_output_is_seen_on_the_console_after_.22booting_the_kernel.22

Best regards,
Pavel

Hi Pavel,

According to wiki page you send me ,I don't find the item "System Type --> TI OMAP Implementations --> Low-level debug console UART" after executing "make menuconfig".

Do you have any other advice?

Best Regards,

Bob

And I couldn't find the item "CONFIG_DEBUG_LL" ?

I need some details from you to be able to provide you advice.

1. Are you using EZSDK 5.05.02.00 or else?

2. Are you using the DM814x EVM or custom board?

3. Are you using the default/pre-built linux kernel or you made some changes?

4. What are your boot arguments?

Regards,
Pavel

This one is for problem #1, No more output is seen on the console after "Starting Kernel...", while you are in problem #2 case, No more output is seen on the console after "booting the kernel"

Regards,
Pavel

This one is enabled by default:

CONFIG_DEBUG_LL=y
CONFIG_EARLY_PRINTK=y

You can check by: make menuconfig -> Kernel Hacking -> [*] Kernel low-level debugging functions

This [*] means that CONFIG_DEBUG_LL is enabled.

Regards,
Pavel

Hi Pavel,

1. Are you using EZSDK 5.05.02.00 or else?

   Is EZSDK 5.05.02.00 a file ?

2. Are you using the DM814x EVM or custom board?

       custom board based on dm8148_evm

3. Are you using the default/pre-built linux kernel or you made some changes?

       the linux kernel is downloaded from TI web

compiler:arm-2009q1
u-boot ver: u-boot-2010.06-psp04.04.00.01
kernel ver: linux-2.6.37-psp04.04.00.01

4. What are your boot arguments?

TI8148_EVM#print
baudrate=115200
verify=yes
bootfile=uImage
ramdisk_file=ramdisk.gz
loadaddr=0x81000000

bootm=tftp 0x81000000 uImage;bootm 0x81000000
bootargs=console=ttyO2,115200n8 root=/dev/mmcblkop2 rw rootwait

Hi Pavel,

It is the second case:

No more output is seen on the console after

Starting kernel ...

Uncompressing Linux... done, booting the kernel.

Best Regards,

Bob

Hi Pavel,

I see.

It has a * before Kernel low-level debugging functions.

The CONFIG_DEBUG_LL is enabled.

Best Reguards,

Bob

Bob,

bob lee said:

console=ttyO2,115200n8

Can you try with console=ttyO0,115200n8

Does it make any difference?

bob lee said:

 Is EZSDK 5.05.02.00 a file ?

EZSDK is Software Development Kit, which contain u-boot, linux kernel, rootfs and demo applications. See the below link for more info:

http://www.ti.com/tool/linuxezsdk-davinci

http://software-dl.ti.com/dsps/dsps_public_sw/ezsdk/latest/index_FDS.html

Regards,
Pavel

Hi Pavel,

There is still no output message.

You are right,We are using EZSDK 5.05.02.00.

Best Regards,

Bob

Bob,

How you load the u-boot? Can you provide me full log of the u-boot console output? How you load the linux kernel (uImage) into RAM?

Regards,
Pavel

Bob,

Are you using DHCP? This is how I load and start the kernel trough the NFS:

TI8148_EVM#setenv autoload no
TI8148_EVM#dhcp
link up on port 0, speed 100, full duplex
BOOTP broadcast 1
DHCP client bound to address 172.20.1.30
TI8148_EVM#setenv bootargs 'console=ttyO0,115200n8 root=/dev/nfs nfsroot=172.20.0.170:/home/users/pbotev/targetfs,nolock rw mem=364M@0x80000000 mem=320M@0x9FC00000 vmalloc=500M notifyk.vpssm3_sva=0xBF900000 ip=dhcp noinitrd'
TI8148_EVM#bootm 0x80009000
## Booting kernel from Legacy Image at 80009000 ...

Can you try setting vmalloc=500M?

Regards,
Pavel

Hi Pavel,

The u-boot is flashed on the nand .

And I download the kernel into RAM by tftp .

Here is the info below:

Bob,

I suspect your bootargs are not fine. Please check mine and reuse them.

TI8148_EVM#setenv bootargs 'console=ttyO0,115200n8 root=/dev/nfs nfsroot=172.20.0.170:/home/users/pbotev/targetfs,nolock rw mem=364M@0x80000000 mem=320M@0x9FC00000 vmalloc=500M notifyk.vpssm3_sva=0xBF900000 ip=dhcp noinitrd'

Best regards,
Pavel

Hi Pavel,

I have set the bootargs=console=ttyO0,115200n8 root=/dev/nfs nfsroot=192.168.5.5:/workspace/boblee/rootfs,nolock rw mem=364M@0x80000000 mem=320M@0x9FC00000 vmalloc=500M notifyk.vpssm3_sva=0xBF900000 ip=dhcp noinitrd.

But it still dosen't work.

Best Regards,

Bob

Bob,

Please attach the linux kernel (uImage) that you are loading into RAM (0x82000000). I will try it on my side.

Regards,
Pavel

Hi Pavel,

I'm sorry for I am at home now .

Can I send the uImage to you torromow?

Best Regards,

Bob Lee

Hi Bob,

Yes, you can send it tomorrow.

Meanwhile I will run some tests with my uImage and provide you the status.

Regards,
Pavel

Hi Pavel,

Can you send your uImage to me ? Thus,I could try it on my board.

Best Regards,

Bob Lee

Bob,

I have tried with mine uImage (default, pre-built), and it works fine. See the below log, which is:

1. Boot the u-boot (1st and 2nd stage bootloaders) from NAND

2. Load the uImage through TFTP from the /tftpboot/uImage at 0x81000000 RAM

3. Use DHCP

4. Use NFS filesystem

I am not able to extract the uImage from this rar, it is giving me empty file after the extraction!

I am attaching my uImage: http://e2e.ti.com/cfs-file.ashx/__key/communityserver-discussions-components-files/716/5430.uImage

This uImage is tested and works fine.

Hi Pavel,

My uImage can be worked at your side ,that means,the kernel is OK.

Maybe the kernel works well,but the console cann't show the message .Is it right?

I see you have this error message - "Auto negotitation failed". This is coming from the below u-boot code:

ti-ezsdk_dm814x-evm_5_05_02_00/board-support/u-boot-2010.06-psp04.04.00.01/board/ti/ti8148/evm.c

/* TODO : Check for the board specific PHY */
static void phy_init(char *name, int addr)
{

if (!miiphy_read(name, addr, PHY_BMSR, &val)) {
        if (!(val & PHY_BMSR_AUTN_COMP))
            printf("Auto negotitation failed\n");
    }

Seems that something is not correct with your specific ethernet PHY on your custom board. Have you gone through the below wiki?

http://processors.wiki.ti.com/index.php/TI81xx_PSP_Porting_Guide#Ethernet_Driver_-_Adding_Custom_Ethernet_Phy

bob lee said:

Yes, your kernel is fine. You can check if the problem is in the console with trying to boot from other sources (not ethernet).

Can you try boot from NAND or MMC/SD card?

BR

Hi Pavel,

I will try boot from NAND.

Hi Pavel,

I have tried boot from nand ,but the result is same as before.

Bob,

bob lee said:

Then it might be console issue.

The DM814x is using UART0 as console. Are you using UART0 at your custom board or other UART instance?

http://processors.wiki.ti.com/index.php/TI81xx_PSP_Porting_Guide#Using_different_UART_than_the_default_EVM_configuration_as_console

Hi Pavel,

We use UART0.I have checked the circuit diagram.

Bob,

Do you have PCIe and or SATA on your custom board? Please see the below e2e thread for more info:

http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/716/t/177166.aspx

Hi Pavel,

There is one SATA port on my custom board.

Bob,

Does this mean that you have SATA, but do not have PCIe? If yes, then disable the PCIe.

I would also recommend you to check the DDR3 memory:

1. Run the u-boot mtest:

http://processors.wiki.ti.com/index.php/DM816x_C6A816x_AM389x_DDR3_Init#Run_mtest

2. Try with slower (than 400MHz) DDR3 frequency - 100/200MHz

3. Do software leveling:

http://processors.wiki.ti.com/index.php/TI814x-DDR3-Init-U-Boot

BR
Pavel

Hi Pavel,

Yes ,you are right ,there is one SATA,no PCIe.

I will try according your infor.

Thanks.

Bob

Hi Pavel,

I have disabled the PCI,but it still stops at "NOR: Can't request GPMC CS".

Now I'm running the mtest.Maybe it will take  a few minutes.

By the way , would you please tell me how to set the DDR3 frequency ,in the uboot or kernel?

Thank you in advance.

The next step of the linux kernel is to enable/init the HDVPSS:

ti-ezsdk_dm814x-evm_5_05_02_00/board-support/linux-2.6.37-psp04.04.00.01/arch/arm/mach-omap2/ti81xx_vpss.c

static int __init ti81xx_init_vpss(void)
{
    int retval = 0;

  printk("Enter into the ti81xx_init_vpss() \n");

    /*if vpss failed to register, none of the below could works*/
    if (ti81xx_vpss_init())
        return -1;
    retval = ti81xx_init_vout();
    retval += ti81xx_hdmi_init();
    retval += ti81xx_fb_init();
    retval += ti81xx_vin_init();
    return retval;
}

static int __init ti81xx_vpss_init(void)
{
    /*FIXME add platform data here*/
    int r;

    printk("Enter into the ti81xx_vpss_init() \n");

    if (cpu_is_ti816x() || cpu_is_dm385()) {
        if (cpu_is_dm385())
            vps_pdata.cpu = CPU_DM813X;
        else
            vps_pdata.cpu = CPU_DM816X;
        vps_pdata.numvencs = 4;
        vps_pdata.vencmask = (1 << VPS_DC_MAX_VENC) - 1;
    } else if (cpu_is_ti814x()) {
        vps_pdata.cpu = CPU_DM814X;
        vps_pdata.numvencs = 3;
        vps_pdata.vencmask = (1 << VPS_DC_MAX_VENC) - 1 \
                    - VPS_DC_VENC_HDCOMP;
    }

    vpss_device.dev.platform_data = &vps_pdata;
    r = platform_device_register(&vpss_device);
    if (r)
        printk(KERN_ERR "unable to register ti81xx_vpss device\n");
    else
        printk(KERN_INFO "registered ti81xx_vpss device\n");
    return r;
}

Can you add printk() as shown above and check if the flow enters the VPSS code and stuck there?

Hi Pavel,

Maybe the next step is phy_register_fixup_for_uid(LSI_PHY_ID, LSI_PHY_MASK, ti8148_evm_lsi_phy_fixup) which is in /board-support/linux-2.6.37-psp04.04.00.01/arch/arm/mach-omap2/Board-ti8148evm.c

I have seen the function : static void __init ti8148_evm_init(void)

 regulator_use_dummy_regulator();
 board_nor_init(ti814x_evm_norflash_partitions,
  ARRAY_SIZE(ti814x_evm_norflash_partitions), 0);
