SEGGER - Martin Administrator

Hello Martin SEGGER

I have a problem with the product embOS of SEGGER.

Description error:
The OS_Start() function does not work. When I go through main() with the IAR debugger step by step, the debugger gets stuck in the OS_Start() function.

I copied the code from the Manual Real-Time Operating System User Guide & Reference Manual from SEGGER page 40. I suppose, that the code in this manual is working.

Question:
Do you have an explanation why the debugger gets stuck in the OS_Start() function?

I have a ScreenShoot. But I don't know, how I can add it to this forum.

Used HW: EFM32GG11 Giant Gecko Starter Kit
