A. Specifying the arguments for a program is hard on "bare metal". It requires determining whether the code has yet entered its main () function and if not patching in pointers to the new arguments.

C and S. Continuing or stepping with a signal is currently not supported. Implementing this would require insertion of an exception, which is not difficult, so this will be an enhancement for the near future.

F. File I/O is not meaningful with a bare metal target, where a file-system may not be present.

i and I. The target is an architectural simulator, executing one instruction at a time. So cycle accurate stepping is not available.

t. The meaning (or use) of the search command is not clear, so this packet is not currently implemented.
