Forums can be like empty rooms, if you don't get an answer, don't just repeat the question, add detail, think of ways of presenting things, and where other use cases and examples might be found, or generated. There's usually more than one way to approach things, and tools chains tend to create a circle. ie assemblers, compilers, linkers, debuggers, disassemblers. The data and technical manuals for the parts should get you instruction codings at a machine level.
If you have a formal business relationship with ST, talk to the FAE assigned to your account, or your other contacts.
