This allows calls to `allocate_memory()` while the VM is running, it will then allocate from the GC heap (unless there is a suitable hole among the supervisor allocations), and when the VM exits and the GC heap is freed, the allocation will be moved to the bottom of the former GC heap and transformed into a proper supervisor allocation. Existing movable allocations will also be moved to defragment the supervisor heap and ensure that the next VM run gets as much memory as possible for the GC heap. By itself this breaks terminalio because it violates the assumption that supervisor_display_move_memory() still has access to an undisturbed heap to copy the tilegrid from. It will work in many cases, but if you're unlucky you will get garbled terminal contents after exiting from the vm run that created the display. This will be fixed in the following commit, which is separate to simplify review. |

LiteX (FPGA) ============ `LiteX <https://github.com/enjoy-digital/litex>`_ is a Python-based System on a Chip (SoC) designer for open source supported Field Programmable Gate Array (FPGA) chips. This means that the CPU core(s) and peripherals are not defined by the physical chip. Instead, they are loaded as separate "gateware". Once this gateware is loaded, CircuitPython can be loaded on top of it to work as expected. Installation ------------- You'll need ``dfu-util`` to install CircuitPython on the Fomu. Make sure the foboot bootloader is updated. Instructions are here: https://github.com/im-tomu/fomu-workshop/blob/master/docs/bootloader.rst Once you've updated the bootloader, you should know how to use ``dfu-util``. It's pretty easy! To install CircuitPython do: .. code-block:: shell dfu-util -D adafruit-circuitpython-fomu-en_US-<version>.dfu It will install and then restart. CIRCUITPY should appear as it usually does and work the same.
