two seperate call stacks with MSP and PSP

[telemedcar]

Hello,

I intended to implement an application without OS. Due to safety concerns I would like to have two call stacks : one for softdevice using MSP and the other for my application using PSP.

Is there an example for how to do this ?

Respectfully, I think you would get more discussion in a forum of an ARM website. Your question is about operating systems and this forum is mostly about radios. Also, see www.adamheinrich.com/.../. That says the NVIC automatically switches contexts (between the two stacks) for interrupts. It is not like the MSP is unused, available for you to use care free.
