The way I do this on the STM32 is to use TCL script JTAG to zero the memory
before allowing GDB to attach.
This is necessary since a previous run of the system can leave valid
contents in the RTOS variables, which are indistinguishable from real RTOS
data.
With the memory zeroed, the system behaves as expected with a single thread
of execution showing in the boot-up code, then multiple threads once the
system has started.
However, if there *is* no memory at those locations after reset, this
scheme will not work when debugging the memory initialization code, so
there needs to be some way to disable the RTOS support.
