title: ARM9 SVC_STACK out of range?
body: <p>I'm debugging some odd ARM exceptions in an embedded system using the IAR workbench toolchain. Sometimes, when an exception is trapped the SVC_STACK is reported as out of range (very out of range!) Is this relevant, or just an artifact of the J-Link JTAG debugger? What is the SVC_STACK used for? It is set to 0x1000 size, but when it is out of range, it is way up in our heap area. Thanks!</p>
