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?
