I'm having similar issues trying to simulate an ADSP-21369 mixed C++ and
asm program using VisualDSP++ 4.5.
When calling my assembly routine from a C++, the disassembly shows that the
compiler translated this into a cjump. However, this action apparently is not
pushing the PC return location onto the PC stack during the call. So when the
assembly routine has completed and the program hits the RTS instruction, there
is nothing on the PC stack to pop, which results in a PC stack underflow.
Does anyone have experience with this issue?
Thanks.
Ken

ADSP-21369 Simulator - PC Stack Underflow

Howdy Ken,
I suggest contacting ADI directly. Sounds like a bug in the simulator,
and they may already have a fix for it.

Thanks Mike. I'll do that. FYI, I upgraded to VisualDSP++ 5.0 and the
problem persists.

Hello guys,
A simple and maybe obvious hint: are those installations patched to the latest updates? If this is a known bug, it is likely to be fixed there.
Regards.
