[Dprglist] NUCLEO STM32 L476RG - using micropython - .dfu files

[Thalanayar Muthukumar]

Thanks Jim for your response. I checked out www.merkles.com and there are a
lot of varied projects you are working on. Wowowow.

Kumar -> I hope he was clueless. Cutting a USB cable to get started seems
too much of a painful exercise to me.

Kumar -> Thanks for the feedback. I may not spend much time on MBED as
STM32CubeIDE is working for me now.

Kumar -> I thought so too, from a price perspective and hence went for the
NUCLEO board as the adaptor is part of the package

Kumar -> I intend to pursue to get micropython work with my NUCLEO STM32
L476RG. Hopefully, I am able to figure out the issues. I will visit your
web site for guidance.
