#6 How to set stack origin?

[Anonymous]

How does bdm-gdb (version 6.3) set the stack origin?
When resetting cpu32, pc and sp value are loaded from
external memory, and vbr is reset to 0. This is usually
ROM, and not the RAM I loaded my application into.
Setting the sp obviously does not set the gdb
assumptions of stack-top.
How can I tell the gdb the real stack top I define? the
load command seems not to do this task and a manual
command is not documented.
Has anybody an idea or a workaround?
