Ishaqe Ahamed
Intellectual 645 points

Part Number: DRA74

Tool/software: Linux

Hi ,

We are  observing Random om omap_hsmmc driver crashes in our system during the system flashing process.

We are using following emmc connected to the DRA6 (Jacinto 6)

Samsung  KLM8G1GESD-B04P 8GB 16 5.1 DE

Have you observed this issue ?

Is there any specific omap hsmmc  driver configuration to support  samsung  KLM8G1GESD-B04P 8GB 16 5.1 DE

    Hi,

    There are no additional configs needed for different eMMC cards.
    The logs you are showing are Kernel crash logs. Are you trying to flash after Kernel has booted?

    What mode are you configuring the eMMC (HS200, DDR50, etc..)?

    Regards,
    Vishal

    It is based on PROCESSOR-SDK-LINUX-AUTOMOTIVE 03_03

    Could you provide more details on the error/crash scenario?
  • 0 in reply to Vishal Mahaveer
    Intellectual 645 points
    Yes ..
    We are in booted into initramfs and flashing the file system after kernel booted up

    Here is the DTB configuration.

    mmc@480b4000 {
    compatible = "ti,dra7-hsmmc", "ti,omap4-hsmmc";
    reg = <0x480b4000 0x400>;
    interrupts = <0x0 0x51 0x4>;
    ti,hwmods = "mmc2";
    ti,needs-special-reset;
    dmas = <0xc6 0x2f 0xc6 0x30>;
    dma-names = "tx", "rx";
    status = "okay";
    sd-uhs-sdr25;
    sd-uhs-sdr12;
    mmc-hs200-1_8v;
    mmc-ddr-1_8v;
    vmmc-supply = <0xc7>;
    bus-width = <0x8>;
    pbias_setup;
    ti,non-removable;
    max-frequency = <0xb71b000>;
    };

    it is not always seen issues, but seen sometimes

    Could you share the final dtb that gets generated?
  • 0 in reply to Vishal Mahaveer
    Intellectual 645 points
    the above share one is generated out of dtb converted to dts .
    Do you need any specific dtb node information ?
  • 0 in reply to Ishaqe Ahamed
    TI__Mastermind 33360 points
    That doesn't look like complete for mmc2.
    Are you not configuring IODELAY values? Like in TI EVM reference dra7xx-evm.dts?
  • 0 in reply to Vishal Mahaveer
    TI__Mastermind 33360 points
    Also, share the full Kernel log when the issue happens.

    Hi Pradeep,

    According to the log, eMMC is coming up in HS200 mode and you also have a SD card and Wi-Fi card connected to different MMC interface.
    The crash happens when you are trying to flash data from SD card to one of the eMMC partitions, is this statement correct?

    The dts shared earlier was incomplete, could you share the final generated dtb or dts?

    Regards,
    Vishal

    IODELAY configurations are missing for MMC, could you guys add it. ANy reason why these were not taken.
    Reference from TI EVM  - http://git.omapzoom.org/?p=kernel/omap.git;a=blob;f=arch/arm/boot/dts/dra7-evm.dts;h=aee34b6d45c1a5c28e9b2c090008c270bee50dc6;hb=9906a0f58aa1e80d22b3fc1f73cf334681028617#l879

    Are there any erase operations in your flashing script? If yes, could you try the below patch?
    http://review.omapzoom.org/#/c/38932

    -3-

    If the above patch doesn't help, could you try reproducing the issue with CONFIG_MMC_DEBUG option enabled in Kernel?
    Disable Wi-Fi to prevent logs from that instance of MMC.

    The IODelay configuration are done from the bootloader in our cases.

    It is found to be correct

    IS there any specific eMMC cache settings we can modify in the omap hsmmc Driver

    I need to check on this, I don't know if there are such settings in omap_hsmmc driver.


    Could you try the patch mentioned in point #2 above and if that doesn't help could you reproduce the issue with MMC_DEBUG as suggested  in point #3?

    Hi Pradeep,

    The debug logs don't have MMC_DEBUG logs.
    Could you try increasing the loglevel of Kernel? Try adding loglevel=9 to Kernel bootargs.

    Hi Vishal,

    Hi Pradeep,

    Thanks for the logs.

    It was mentioned that this issue is seen sometimes. Do you know how many boards exhibit this behavior?
    Also, do you know what was the operating conditions at time of error.

    HI could you please let us know the recommended value for max_segs ?

    what is the impact if we reduce the value to half ?

    if (host->pdata->controller_flags & OMAP_HSMMC_HAS_HWPARAM) {
    val = OMAP_HSMMC_READ(base, HL_HWINFO);
    if (val & MADMA_EN)
    host->use_adma = true;
    }

    /* Since we do only SG emulation, we can have as many segs
    * as we want. */
    mmc->max_segs = 1024;

    mmc->max_blk_size = 512; /* Block Length at max can be 1024 */
    mmc->max_blk_count = 0xFFFF; /* No. of Blocks is 16 bits */
    mmc->max_req_size = mmc->max_blk_size * mmc->max_blk_count;

    Hi,

    Let me get back to you on the question about max_segs.

    Could you answer the previous questions on how many boards and operating condition of the board where the MMC crash is seen while flashing?

    Regards,
    Vishal

    TI__Mastermind 33360 points
    Regarding max_segs:

    Changing max_segs might have throughput impact. It should neither be too large nor too small. Having 1024 (sg entries) has worked well for us so far in omap_hsmmc

    You can reduce it to half if you want, but do enough testing to make sure the change does not have adverse effect on you throughput.
