Tools/Memory Checker

  * The default base address for the register bank of the memory checker is 0x00004200. This address can be changed but must stay close to 0 to fit on some processor instruction immediate field. You should consider this if you already have components at these addresses.
  * The Memory checker registers bank is protected by a magic value and is unlikely to be modified by an other running software.

+With the following code using an unitialized stack variable to set a global:
+
+{{{
+int foo;
+
+void _main(void*unused)
+{
+  int bar;
+  foo = bar;
+
+  // ...
+}
+}}}

+We get the following output:
