This command controls the semihosting settings in the debugger. Semihosting is used to communicate input/output requests from application code to the host workstation running the debugger.
Note
These settings only apply if the target supports semihosting and they cannot be changed while the target is running.

stdoutfor semihosting operations.top-of-memoryaddressSpecifies the top of memory.
stack_heap_optionsSpecifies finer controls to manually configure the base address and limits for the stack and heap. If you use

stack-limitaddressThe end address of the stack.
heap-baseaddressThe base address of the heap.
heap-limitaddressThe end address of the heap.
enabledautoAutomatically enables semihosting operations if appropriate when an image is loaded. This is the default.
offDisables all semihosting operations.
onEnables all semihosting operations.
Note

For example:
set semihosting top-of-memory
