Porting software / firmware from one architecture to another confusion


Porting software / firmware from one architecture to another confusion

Hope that helps Since you asked for a few examples here are two relatively simple non-portable examples in C, just to start off.
(Do note that these are examples of non-portable code. Porting activities may also include tasks not related to existing code, like writing an interface or a new hardware abstraction layer for a custom target/processor)
code :
typedef struct _M {
  uint32_t a;
  uint32_t b;
} M;

uint8_t *p = (uint8_t *)malloc(100);

M *m = (M *)p;

printf("%d", m->b); //may cause hard fault at m->b on Cortex-M0

I wish did fix the issue. The Rational Unified Process describes "Component-based architecture" as one of its seven core "best practices". It's not entirely clear to me what this means. On the web, the best description seems to be this one, from the whitepaper "Rational Unified Process: Best Practices for Software Development Teams":

may help you . Testing comes in a number of forms and can be performed at different stages. Apart from design validation before code is even written, code testing may be divided into unit testing, integration testing, system testing and acceptance testing (though exact terms and number of stages may very). In the V model, these would correspond horizontally with stages in requirements and design development. Also in development and maintenance you might perform regression testing - ensuring that fixed bugs remain fixed when other changes are applied.
As far as tools are concerned, these can be divided into static analysis and dynamic analysis. Static tools analyse the source code without execution, whereas dynamic analysis is concerned with the behaviour of the code during execution. Some (expensive) tools perform "abstract execution" which is a static analysis technique that determines how the code may fail during execution without actual execution, this approach is computationally expensive but can process far more execution paths and variable states than traditional dynamic analysis.

around this issue Firmware is a kind of Software
A block of computer instructions, no matter how permanent and malleable they are, is Software.

This might help you The concept of an "event bus" is over-complicated. In many cases, the simplest approach is to minimize the number of things that need to happen asynchronously, but instead have a "main poll" routine which runs on an "as often as convenient" basis and calls polling routines for each subsystem. It may be helpful to have such routine in a compilation by itself, so that the essence of that file would simply be a list of all polling functions used by other subsystems, rather than anything with semantics of its own. If one has a "get button push" routine, one can have a loop within that routine which calls the main poll routine until a button is pushed, there's a keyboard timeout, or something else happens that the caller needs to deal with. That would then allow the main UI to be implemented using code like:
code :
void maybe_do_something_fun(void)
{
  while(1)
  {
    show_message("Do something fun?");
    wait_for_button();
    if (button_hit(YES_BUTTON))
    {
      ... do something fun
      return;
    }
    else if (button_hit(NO_BUTTON))
    {
      ... do something boring
      return;
    }
  } while(1);
}

hop of those help? They are not distinctly separate things, or even well defined. Firmware is a subset of software; the term typically implies that it is in read-only memory:
Software refers to any machine executable code - including "firmware". Firmware refers to software in read-only memory
