Linux/TDA2SX: How should I use the hs200 mode of emmc?

Part Number: TDA2SX
Other Parts Discussed in Thread: DRA742, DRA752

Tool/software: Linux

hi ti:

                    mmc1: mmc_select_hs200 failed, error -74

[ 1.365155] : switch to mmc1 failed
[ 1.368671] mmc1: clock 25000000Hz busmode 2 powermode 2 cs 0 Vdd 21 width 3 timing 0

[ 1.420847] mmcblk1: p1 p2

The startup log shows that selecting hs200 mode failed.

This is my device tree configuration, and I want to know what went wrong.

  • Hi,

    Can you share the full Kernel log?
    Also, share the final .dtb file used for your board.

    Regards,

  • hi Vishal

    I have uploaded relevant attachments, please check.

    Regards
  • Hi,

    Could you share the kernel logs by enabling MMC_DEBUG option?

    - enable CONFIG_MMC_DEBUG in kernel defconfig
    - Update bootargs to increase loglevel (append loglevel=9 to KERNEL_CMDLINE)


    Regards,
    Vishal

  • Thanks for the logs, we are analyzing the logs.

  • Hi,

    The debug logs is indicates switch error reported by the card when request to switch to HS200 mode was made.

    [ 1.704949] mmc1: mmc_select_hs200 failed, error -74
    [ 1.704951] : switch to mmc1 failed

    According to JEDEC spec, SWITCH_ERROR (bit 7) in response means the eMMC device did not switch to expected mods as requested by the SWITCH command.

    Can you check,
    1) The eMMC device used supports HS200 mode.
    2) If the voltage settings are correct for the eMMC card to support HS200 mode (J6 only supports HS200 mode with 1.8v)


    Regards,
    Vishal

  • hi Vishal

    clock: 25000000 Hz
    vdd: 21 (3.3 ~ 3.4 V)
    bus mode: 2 (push-pull)
    chip select: 0 (don't care)
    power mode: 2 (on)
    bus width: 3 (8 bits)
    timing spec: 0 (legacy)
    signal voltage: 0 (1.80 V)
    driver type: 0 (driver type B)

    I want to know whether the voltage is VCC or VCCQ.

    I uploaded the schematic diagram and a screenshot of the chip manual.

    Regards
  • Hi,

    So, 1.8v and HS200 is supported.

    Could you confirm the voltage level for MMC2 VCCQ?

    Regards,
    Vishal
  • Could you also confirm that CONFIG_PINCTRL_TI_IODELAY is enabled in your Kernel config?
  • hi Vishal
    Thank you very much。
    I have solved the problem now. My VCCQ voltage is 3.3v, now I change it to 1.8v, and I can use hs200 mode.
    Regards
