Thanks Darby for the reply, 
I updated the Board Manager on Arduino IDE to 1.0.15 (also tried 1.0.16) --> the tried updating the Bootloader using Arduino IDE (but failed) with the following error message:

    Arduino: 1.8.5 (Linux), Board: "OpenCR Board, OpenCR Bootloader"

    java.lang.NullPointerException
        at cc.arduino.packages.uploaders.SerialUploader.burnBootloader(SerialUploader.java:362)
        at processing.app.Editor.lambda$handleBurnBootloader$14(Editor.java:2519)
        at java.lang.Thread.run(Thread.java:748)
    Error while burning bootloader.

    This report would have more information with
    "Show verbose output during compilation"
    option enabled in File -> Preferences.

I made sure the

>  lsusb

is showing the STMicroelectronics (NOTE: There is no DFU mode written as you mention in the emanual - but this entry in lsusb starts showing up only after DFU mode triggered on using Boot + Reset button)

Can you let me know some tips to go ahead with debugging?

Thanks
