Linux on AM335x IDK

Prateek Raghuvanshi
Intellectual 630 points

Hi all,

         I am trying to port linux for AM335x IDK. I have done necessary changes in U-boot code, while booting up kernel hangs on following line:

[    1.724365] Waiting for root device /dev/mmcblk0p2...

Can any one suggest me what is the problem?

What i have already tried is:

1. Card detect to -EINVAL in static struct omap2_hsmmc_info am335x_mmc[] __initdata = {
2. Tried to disable card detect in board file, but enabled it while doing 1.

3. Changed PINMODE  from 7 to 4-     {"mcasp0_aclkr.gpio3_18", OMAP_MUX_MODE4 | AM33XX_PIN_INPUT_PULLDOWN},


What am i missing here? What could be the reason for this? Any help is appriciated.

Thanks in Advance.

    It may be waiting for MMC0_CD input, which isn't connected on the IDK. This post could be related to your issue: http://e2e.ti.com/support/arm/sitara_arm/f/791/t/249718.aspx

    Hi Prateek,

    You may also check the prepare_namespace() function inside do_mounts.c file in the kernel. This is where your system hangs:

        /* wait for any asynchronous scanning to complete */
        if ((ROOT_DEV == 0) && root_wait) {
            printk(KERN_INFO "Waiting for root device %s...\n",
                saved_root_name);
            while (driver_probe_done() != 0 ||
                (ROOT_DEV = name_to_dev_t(saved_root_name)) == 0)
                msleep(100);
            async_synchronize_full();
        }

    Check why your system doesn't exit this while loop, taking in regard what Biser said.

    Best regards,
    Miroslav

    Also while going through the point where kernel was hanging, i obsereved that function blk_lookup_devt(s, part); in same do_mounts.c called in line number 240.

    Does that mean mmc card is not detected? I really can't understand log, please help.

    thanks.

    Hi Prateek,

    The log shows a NULL pointer dereference error. This means that somewhere during the mmc start/init you are trying to use an uninitialized resource. Perhaps an uninitialized structure member? Is the blk_lookup_devt() function where your system hangs. Please trace the system hang using prints and when you pinpoint it, you will probably find what is causing it. Please post your progress here.

    Best regards,
    Miroslav

    Hi,

    Thanks Mirosalv. Please see the log attached. I see a time out error in my log mmc0: req done (CMD52): -110: 00000000 00000000 00000000 00000000, i think its because of No card detect. Is there any way or work around for it??

    And as far as any uninitialized structure is concerned i have gone through the whole loop i couldn't recognize any such structure.

    Hi all,

             I have pin pointed the error using gdb and kernel log. It is in following line.

    (gdb) list *(omap_hsmmc_start_command+0xc8)
    0x1a0 is in omap_hsmmc_start_command (drivers/mmc/host/omap_hsmmc.c:919).
    914        /*
    915         * Unlike OMAP1 controller, the cmdtype does not seem to be based on
    916         * ac, bc, adtc, bcr. Only commands ending an open ended transfer need
    917         * a val of 0x3, rest 0x0.
    918         */
    919        if (cmd == host->mrq->stop)
    920            cmdtype = 0x3;
    921    
    922        cmdreg = (cmd->opcode << 24) | (resptype << 16) | (cmdtype << 22);
    923    

    Structure host->mrq is NULL. But how do i correct it. Because kernel calls same function 4 to 5 times before crashing. Why does it go to this function 4 or 5 times but doesn't crash? Any pointer will be help full

    Thanks in advance.

    Has anyone discovered why this is occurring as I am seeing the same issue when I enable spi0?

    I fixed my issue by changing the order in which I called the spi0_init() within my custom dev_cfg structure.

    static struct evm_dev_cfg gemini_dev_cfg[] = {
        {am335x_rtc_init, DEV_ON_BASEBOARD, PROFILE_ALL},
        {clkout2_enable, DEV_ON_BASEBOARD, PROFILE_ALL},
        {rmii1_gemini_init,     DEV_ON_BASEBOARD, PROFILE_NONE},
        {usb0_init,     DEV_ON_BASEBOARD, PROFILE_ALL},
        {usb1_init,     DEV_ON_BASEBOARD, PROFILE_ALL},

    // {spi0_init,     DEV_ON_BASEBOARD, PROFILE_NONE}, /* moved spi0 from here */
        {gpmc_gemini_init, DEV_ON_BASEBOARD, PROFILE_ALL},                                                                                                                 
        {uart5_gemini_init, DEV_ON_BASEBOARD, PROFILE_ALL},                                                                                                                
        {mmc2_wl12xx_init,      DEV_ON_BASEBOARD, (PROFILE_0 | PROFILE_3 |  PROFILE_5)},                                                                                                               
        {mmc0_init,     DEV_ON_BASEBOARD, (PROFILE_ALL & ~PROFILE_5)},
        {uart1_wl12xx_init,     DEV_ON_BASEBOARD, (PROFILE_0 | PROFILE_3 |  PROFILE_5)},
        {wl12xx_init,   DEV_ON_BASEBOARD, (PROFILE_0 | PROFILE_3 | PROFILE_5)},

        {spi0_init,     DEV_ON_BASEBOARD, PROFILE_NONE}, /* moved spi0 init to here */
