TMDSIDK574: Cannot boot TMDSIDK574 Rev. B

Gregory Smith1
Intellectual 325 points

Part Number: TMDSIDK574

We purchased two TMDSIDK574 development kits.  One is working, the other does not boot. 

For the TMDSIDK574 that doesn't boot there is no indication of life from the HDMI or serial console

I have tried booting:

* both included microSD cards (Linux SDK and Industrial SDK),.

* An SDK build of the Linux-RT and copy to a microSD.

* A dd duplicate of a  microSD known to boot in our working TMDSIDK574 Rev.B

Are there further steps I should take?  Thank your for your help.

    Hi Gregory,

    There are known issues with Rev 1.0B. Basically SD card assembly issues that do not let you boot.

    The typical behavior:
    U-Boot SPL 2019.01-ga141f7abfd (Jan 05 2020 - 10:23:38 +0000)
    DRA762-GP ES1.0 ABZ package
    no pinctrl state for default mode
    Card did not respond to voltage select!
    Firmware loading failed
    Trying to boot from MMC1
    no pinctrl state for default mode
    Card did not respond to voltage select!
    spl: mmc init failed with error: -95
    SPL: failed to boot from all boot devices
    ### ERROR ### Please RESET the board ###

    If you are experiencing the same issues then:

    This is being root caused to a board issue related to SD interface.

    Hence request you to submit an RMR request to procure a replacement 
    newer version board with the issue fixed. Till you receive the newer 
    version of the board request to continue on working 1.0A boards.

    Until then this thread can be closed.

    For any further queries you can reply on this very thread.

    RMR procedure:
