Unless you are modifying the Mock Turtle core itself, the following values are
fixed: ``ORIGIN = 0x00000000`` for the *ram*, ``ORIGIN = 0x40200000`` for
the *smem*. The ``LENGTH`` value for *ram* depends on the CPU memory size on
which the firmware will run; the ``LENGTH`` value for *smem* depends on the
Mock Turtle shared memory size; both these values depend on the FPGA synthesis
configuration of the target Mock Turtle instance.
.. note::
It is possible to add more linker script commands to ``trtl-memory.ld`` but
then the behavior is undefined. If you need more linker script commands,
please write your own linker script file and pass it to the build system
by using ``TRTL_LD_SCRIPT``.
You can build such firmware application by calling ``make`` from the You can build such firmware application by calling ``make`` from the
