> I’ve completed my Bachelor of Technology in (Electronics And Communication Engineering ) from a regular college where, unfortunately, embedded systems and low-level programming weren’t taught in depth.
More often than not, this is the usual state of affairs.
When institutions offer courses more specialized on (lower-level) embedded development, it is often at the initiative of the lecturer doing the course. And they usually don't delve too deep into it either.
While it was decades ago (early '90s), my own IT / computer science education was a joke judged by modern standards. Almost all I know now I learned myself, barely escaping Fortran at the university ...
What you should have learned is the scientific base (math, physics, electrical engineering), structured thinking, and problem solving skills, and a willingness to learn.
Apply these to your field, and your will be fine.
> No sir, I come from a very small tribal city, and there’s no one locally with expertise in this domain. ...
I have no knowledge about the situation in India, or related experience. Probably very few here do.
But ST has a lot of online courses (YT video tutorials) for certain topics, which might be helpful.
And in your situation, I would check out other vendors (NXP, TI, etc.) which have similiar environments and tutorials.
