20 | document heapwalk |
21 | Walks the heap and dumps each chunk encountered. | |
22 | It will also lists the line and source filename from where the chunk was | |
23 | allocated if not a freed chunk. Requires that HEAP_WALK be set to a value of 1 | |
24 | in the Smoothie makefile. | |

40 | Displays the current heap size. | |
41 | Can provide an optional argument specifying the location of the base address | |
42 | for the heap. This isn't required if you have HEAP_WALK enabled in the makefile | |
43 | but if that features isn't enabled, you will want to run | |
44 | "maintenance info section .heap" to determine this base address and then | |
45 | pass it as an argument to this comand. | |

73 | document maxstacksize | |
74 | Displays the maximum stack amount of stack used. | |
75 | This can take awhile to run as it walks the area between the top of heap and | |
76 | the current top of stack to look for where initial fill values have been | |
77 | overwritten by stack writes. | |
