I do not have the skills to= write my own runtime or even part of a runtime. -Patrick I find this situation rather insane as well. As you said, Ada is an embedd= ed language. OK, to be more precise, Ada is a language which had as a prim= ary design goal the creation of embedded applications. And yet it seems in= practice to be quite impossible to use on embedded applications without a = full-blown OS/RTOS underneath it. =20 One _can_ do Ada tasking, at least, using a bare metal implementation - the= GNAT Lego Mindstorms port does this, I believe. Sadly, there does not see= m to be a cookbook as to how to create such a bare metal port for other dev= ices/families. I find the situation be be rather astonishing. As I pointe= d out in another thread, there are 4 billion ARM chips produced each year, = and Ada is an excellent fit for every one of those 4 billion chips, but the= Ada community doesn't seem to be interested in that market, or any of the = numerous other 32-bit embedded parts available. This strikes me as madness= if one wants Ada to grow and prosper.
