TDA4VMXEVM: TDA4VM EVM UFS

HI.master    

We have executed: UFS utils desc - t 1 - W config_ desc_ data_ ind_ 0 -p /dev/bsg/ufs-bsg0

However, the UFS device has not been scanned, and the detailed log is in the file.

    We've read this post, and I've followed it. You can see the attached log file. UFS devices that still cannot be scanned.

    Hi,

    If you look carefully:

    3) execute the below command from the kernel command prompt

    "ufs-utils desc -t 1 -w ./config_desc_data_ind_-p /dev/bsg/ufs-bsg0"

    You need to first write but you are doing a read in your sequence which overwrites
    the ./config_desc_data_ind_-p file. So just follow the exact
    sequence as given in the before mentioned e2e.

    Freshly download and do not read:

    ufs-utils  desc -t 1 -p /dev/bsg/ufs-bsg0 


    Do not do the above step.

    Also hard reboot the system before checking u-boot.

    If the above works then please resolve.

    Best Regards,
    Keerthy
