Linux: Linux/RTOS booting problem

Tool/software: Linux

Hi,

I am using some TDA2xx custom board with PROCESSOR-SDK. I am getting "Waiting for root device PARTUUID=99df27d8-02..." error. I have looked into threads on TI forum and applied suggestions below but did not help

  1. I have used Class 10 SD card instead of lower one
  2. I have checked SD card detection GPIO pin from u-boot it is working
  3. When initializing Linux I have tried both from scripts and by hand

this is my boot-log

/cfs-file/__key/communityserver-discussions-components-files/791/2251.boot_2D00_log.txt

Do you have any suggestion?

Thanks.

    Hi,
    If we start from the first error in the timeline then kindly try this:
    e2e.ti.com/.../308675

    Let us know if anything changes.

    Regards,
    Stan

    P.S. The solution in the other thread is the other way around. Of course in your case will need to change from MMC1 to MMC0 , because the latter is the SD card interface.

    Hi,

    I have forwarded your question to a kernel expert for further help.

    Hi,

    1. Have you taken care of PAD config (pin muxing)?

    2. Are you able to read from sd car din u-boot?

    stop at u-boo tprompt by pressing any key during u-boot.

    mmc dev

mmc dev 0

fatls mmc 0:1

    3. Can you share your board dts (device tree) file?

    2. Have you tried with a different card?

    Regards,

    RK

    Hi, Ravikumar!
    We are trying to port linux to A15 on our custom board with TDA2xx (VISION_SDK_02_12_01_00) .. This is something we have already managed to do on Ti’s EVA board.
    However, when we use our board, we cannot get past this error:

    Waiting for root device PARTUUID=3dd2cf74-02...

    The boot process stops there and we cannot get access to shell

    When we stop the booting process, we can read the data from SD card using the commands:
                    mmc dev
                    mmc dev 0
                    fatls mmc 0:1
    Then we get the list of files stored on the fat partition called 'boot' (comprising MLO, etc).
    Our complete log is shown below.
    We are also able to perform the 'ext4ls' command, like this:
                    ext4ls mmc 0:2
    Then we get the list of files stored on the ext4 parition, called 'rootfs'.
     
    We have tried to boot both from C4 and C10 MicroSD cards, the result is the same.
    Could you give us more information about changing the boot arguments in <u-boot_dir>/include/configs/am335x_evm.h ?
    Could this be caused by:
    i2c_write: error waiting for data ACK (status=0x116)
    pcf8575_i2c_write_le16 i2c write failed to addr 21
    We don’t have this i2c expander on our board.
    Could you help us solve this issues?
    If you need some of the .dts files, please let us know which files exactly we should give you.
     Our complete log is shown below:

    Hi,

    You are seeing this error because there's no SD/MMC card detected by kernel on your board.

    You may also notice that SD card enumeration stopped after "[    4.464891] omap_hsmmc 4809c000.mmc: Got CD GPIO"

    If successful you'll see something like below

    [    3.678455] mmc0: new high speed SDHC card at address 1234                                                                        │··
    [    3.684214] mmcblk0: mmc0:1234 SA08G 7.42 GiB                                                                                     │··
    [    3.689691]  mmcblk0: p1 p2 

    Please follow below steps

    1. Please share your board device tree file (dts).

    2. Enable CONFIG_MMC_DEBUG as described here http://processors.wiki.ti.com/index.php/Processor_SDK_Linux_Automotive_FAQ#How_do_I_debug_.2F_get_additional_debug_information_for_MMC.2FSD.2FSDIO_issues.3F

    I doubt the voltage supply is not configured correctly in device tree.

    Check if you have added regulator nodes to device tree file as connected on your board.

    You may refer to dra7-evm.dts for an example.

    &mmc1 {                                                                                                                             
            status = "okay";                                                                                                            
            vmmc-supply = <&evm_3v3_sd>;                                                                                               
            vmmc_aux-supply = <&ldo1_reg>;

    Regards,

    RK

    Hi Stefan,
    Once you have ensured the voltage regulator connections are described in device tree.
    Please share complete boot log with "CONFIG_MMC_DEBUG" enabled.

    Regards,
    RK

    Dear Ravikumar,

    I have made the following modification in my device tree and it solved my issues. Now I can run linux on our custom board.

    &mmc1 {
    status = "okay";
    vmmc-supply = <&evm_3v3_sw>;
    vmmc_aux-supply = <&ldo1_reg>;

    Thanks a lot! :)

    Regards,
    Stefan.
