Linux/AM6548: UBOOT/AM6548: SD card timeout error when boot from ospi flash

user5772774
Intellectual 660 points
Part Number: AM6548

Tool/software: Linux

Hi TI,

I encountered the following error when boot from opsi flash(MMC0), So I can't access SD card(MMC1).

MMC: sdhci@0: 0, sdhci@0: 1
sdhci_send_command: MMC: 1 busy timeout increasing to: 200 ms.
sdhci_send_command: MMC: 1 busy timeout increasing to: 400 ms.
sdhci_send_command: MMC: 1 busy timeout increasing to: 800 ms.
sdhci_send_command: MMC: 1 busy timeout increasing to: 1600 ms.
sdhci_send_command: MMC: 1 busy timeout increasing to: 3200 ms.
sdhci_send_command: MMC: 1 busy timeout.

But it can work when I booted from SD card. Under this conditions, MMC0 and MMC1 both work good.

My setup:

AM6548 EVM board

Processor SDK 05_01_00_11

Thanks

BS

    Hi user5772774,

    Could you please provide the whole boot up log (not just part of it)?

    Make sure you are following below user guide:

    I make a flash.bin with three files: tiboot3.bin and tispl.bin and u-boot.img, their order is "mtdparts=47040000.ospi.0:512k(ospi.tiboot3),2m(ospi.tispl),5m(ospi.u-boot),128k(ospi.env),-@8m(ospi.rootfs)", Then I burn spiflash.bin into the ospi flash. But I encountered the bellow problem when booted from ospi flash.

    The whole boot up log of u-boot as following:

    Hi TI，

    　　Now I enable the macro 'CONFIG_ENV_IS_IN_SPI_FLASH=y' to save environment variable to spi flash （Previously it be saved in the SD card）, I don't encounter above problem, bootloader can startup from spi flash then boot kernel and mount rootfs from SD card. so in this way, we can bypass the trap! but still don't find the root cause...

    The whole bootloader log as following:

    U-Boot SPL 2018.01-00446-g02efeaa (Nov 15 2018 - 10:19:59)

    user5772774,

    On the failing case you have: u-boot, kernel and rootfs on OSPI Flash and boot env on SD card (MMC1), is that correct?

    On the good case you have: u-boot, boot env, kernel and rootfs on OSPI Flash, is that correct?

    How eMMC (MMC0) is involved in your use case, can you provide more details? We have some known issues related to eMMC/MMC0 timeout:

    software-dl.ti.com/.../Release_Specific_Release_Notes.html

    LCPD-13667 - mmc 0 timeout and env could not be saved to eMMC on one board (farm26)

    LCPD-13666 - Seeing mmc0 timeout errors on some boards

    LCPD-13371 - mmc0 enumeration commands timeout in kernel

    Pavel
