in "main" I get an error message "CSTACK pointer is 0000 0000, outside

I believe I've written the memory descriptor file properly. The SP
register contains a valid address for the stack pointer.

Are you using hand-rolled startup code, or vendor-provided?

It sounds like the RTL expects to have an internal variable
initialized, separately from the machine's stack pointer. A quick
Google suggests that you should have a separate CSTACK section; what
does the MAP file say about CSTACK?
