Another DM8148 SD Linux Boot Issue

Tom Morrison
Intellectual 410 points
Other Parts Discussed in Thread: DM385

We have a custom board which is based heavily upon the DM8148-EVM

The Linux Kernel is a combination of the IPNC & RDK (delivered by a 3rd party (TI recommended)

When we have the Ethernet Phy populated on the board, we can boot from the SD Card ('run boot_mmc' just fine.

When we remove the Ethernet Phy (to save costs), we are unable to boot from the SD Card. Linux hangs in the boot process with:

   "Waiting for Root Device /dev/mmcblk0p2"

Further, if we boot from NAND - it boots to Linux successfully and the SD Card can be mounted and files can be read & written succesfully. I should note that all the Linux Images are the same (SD Card or NAND). 

It can't be a "loose" pin - because it can be read/detected in other boot situations. All that is different is the ethernet phy is de-populated?

Does this sound familiar to anybody?

    Hi Tom,

    Did you make any software changes in the linux kernel or changes in the boot arguments when removing the ethernet PHY?

    Best regards,
    Pavel

    Essentially, there were NO changes to kernel or boot arguments...

    Even if its built with support for Ethernet - the driver probe indicates there is NO PHY and that it should just continue without finding a device to continue

    No, I did not change the boot arguments and does assign an IP address to that device - which shouldn't matter as well?

    Further, I built the linux kernel with debug information and put an ICE on it - to see where it was hanging here is the stack when I connected and stopped.

    Tom,

    No, I did not change the boot arguments and does assign an IP address to that device - which shouldn't matter as well?

    Can you provide me full boot up log (u-boot + kernel) in the successful boot case and in the failing boot case?

    Regards,
    Pavel

    Hopefully it is attached - the first being the "Hang" (booting from MMC) and then after power-reset - booting from NAND

    Tom,

    Tom Morrison said:
    then after power-reset - booting from NAND

    You boot u-boot and linux kernel from NAND, but not the root filesystem?

    Tom Morrison said:
    the first being the "Hang" (booting from MMC)

    You can try remove Ethernet support from the linux kernel and the boot arguments (Kernel command line).

    When I boot from NAND - the root file system is on NAND

    I've also tried to remove support for the Ethernet Chip from the Linux Kernel and it still hangs

    I will try changing boot args...

    So it was suggested to me to modify board-ti8148evm.c like this:

    static struct omap2_hsmmc_info mmc[] = {

        {
            .mmc        = 1,
            .caps       = MMC_CAP_4_BIT_DATA | MMC_CAP_NEEDS_POLL,
            .gpio_cd    = -EINVAL, /* Dedicated pins for CD and WP */
            .gpio_wp    = -EINVAL,
            .ocr_mask   = MMC_VDD_33_34,
        },
        {}  /* Terminator */
    };

    This actually worked - which means there there is an issue with pin mux (between Kernel & u-boot) with the SDCD pin for the MMC. 

    Looking at MUX map in mux814x.c - there is one related 'mux' wtih mmc1_sdcd_mux1 which has something another mode related to mii I/O somewhere: pr1_mii0_rxlink_mux0

    I haven't found a good explanation of this pin and how it might related to our ethernet chip, because that is THE ONLY possible combination related to each other?

    I'm stumped!

    Sorry I missed this response - but had already tried this method (re-compile the kernel without MAC) and changing the boot args. As my other (just posted) comment - I did get it to work, but I"d like to figure out exactly what pin mux is wrong and see if I can correct it!

    Hi Tom,

    Tom Morrison said:
    .gpio_cd    = -EINVAL, /* Dedicated pins for CD and WP */

    This is also valid for DM814x device. We have dedicated pin for CD (Card Detect), so we do not use GPIO pin (GP1[6]) for that purpose. The CD pins are SDx_CDSD.

    http://processors.wiki.ti.com/index.php/TI81xx_PSP_Porting_Guide#Adding_support_to_enable_multiple_MMC.2FSD_instances

    Set ".gpio_cd" and ".gpio_wp" as "-EINVAL" in case of DM8148 due to dedicated pins for CD (card detect)

    The pin mux can be checked from the device datasheet. In case of DM814x, all SDx_CDSD pins (SD0_CDSD, SD1_SDCD, SD2_CDSD) are not multiplexed with Ethernet related pins.

    mux814x.c:

    _TI814X_MUXENTRY(UART0_CTSN, 0,
                "uart0_ctsn", "uart4_rxd_mux3", NULL, "dcan1_tx",
                "spi1_cs3", NULL, "mmc0_sdcd", NULL),
        _TI814X_MUXENTRY(UART0_RTSN, 0,
                "uart0_rtsn", "uart4_txd_mux3", NULL, "dcan1_rx",
                "spi1_cs2", NULL, "mmc2_sdcd", NULL),    /* non DM385 */

    _TI814X_MUXENTRY(SPI0_CS1, 0,
                "spi0_cs1", "mmc1_sdcd", "sata_act0_led", NULL, NULL,
                "xdma_evt_1_mux1", "timer4_mux1", "gpio1_6"),

    Regards,
    Pavel

    This really didn't answer my question:

    I was already quite familiar with these entries but I pointed out the additional mux that I did not understand:

    _TI814X_MUXENTRY(MCASP0_AXR2, 0,
             "mcasp0_axr2_ti811x", NULL, "pr1_mii0_rxlink_mux0",
             "pr1_pru0_pru_r31_6", "pr1_pru0_pru_r30_6",
              "i2c3_sda_mux0", "ehrpwm1_tripzone_input_mux1", NULL,
              "mmc1_sdcd_mux1", NULL, NULL, NULL),/*for TI811X only */

    If I didn't poll for SD Card - then I would not have seen it (because it seems that pin might be connected to something else internally/externally that does not allow for this to be seen directly.

    I just don't understand the mux that well? What is mmc1_sdcd_mux1?

    How can this be related - potentially to pr1_mii0_rxlink_mux0 - and when I remove all signals connected to Ethernet Phy (including MII interface).

    ?

    Tom,

    Tom Morrison said:
    ,/*for TI811X only */

    Thus mux entry is valid for TI811x device only (DM811x, J5Eco, DRA62x). This is not valid for DM814x/TI814x device.

    In TI811x device, the MMC1/SD1 Card Detect pin (SD1_SDCD on AF4) is multiplexed with MCA[0]_AXR[2] and I2C[3]_SDA.

    Tom Morrison said:
    I just don't understand the mux that well? What is mmc1_sdcd_mux1?

    In TI811X device, MMC1/SD1 Card Detect signal (SD1_SDCD) can be routed to two physical external pins:AF17 (mux0) and AF4 (mux1). Thus when the signal is routed to AF17, its name is mmc1_sdcd_mux0 and when routed to AF4, its name is mmc1_sdcd_mux1. For more information about the Multi-Muxed option, see DM814x datasheet, section 4.3 Pin Multiplexing Control.

    Tom Morrison said:
    How can this be related - potentially to pr1_mii0_rxlink_mux0

    In TI811x/DM811x/J5Eco/DRA62x device, the mmc1_sdcd_mux1 signal can be selected on the AF4 pins, instead of pr1_mii0_rxlink_mux0 signal.

    pr1_mii0_rxlink_mux0 signal is NOT related to the Ethernet/EMAC module.
