Semihosting parameters of FVP

Oscar Huang

Hello,

I don't understand the concepts of some semihosting paramsters, For example:

1. semihosting-cmd_line:  What is this? When will this command line be execucted, and by what entity?

2. stack and heap related: semihosting-stack_base, semihosting-stack_limit, semihosting-heap_base, semihosting-heap_limit. What do the stack and the heap here refer to? Do  they relate to the firmware stack and heap running on the models in any way? 

It's much appreciated if you can educate me on these concepts, or point me to any resources by which I can learn them by myself.

Thanks

-Oscar

    For #2, yes, these are the default values for the stack and heap pointers that code running on the model would use. It is normal for an application to specify these directly, but a simple 'hello world' would get these from the model, via the debugger.
