Warning when compiling task_manager

[Denis Shreiber]

Hello Dear Developers!

I have a warning when I compile Task Manager

The warning is generated at this code in cmsis_gcc.h file:

__attribute__( ( always_inline ) ) __STATIC_INLINE void __set_PSP(uint32_t topOfProcStack)
{
  __ASM volatile ("MSR psp, %0\n" : : "r" (topOfProcStack) : "sp");
}

Despite this my program with Task Manager works fine. But could you tell me if this could lead to potential problems?

Environment:

• NRF5 SDK 16.0.0
• SES 5.32
• nrf52832

Hi,

I do not see how this should cause problems, so it should be safe to ignore it. That said, the __set_PSP implementation has changed in the CMSIS that is part of SDK 17, so that should be good. Also note that you may see some compatibility issues when using a different Segger Embedded Studio version than what the SDK was tested with (though usually not anything major), and SDK was tested with SES 4.18.

Thanks, Einar

Нou gave me important information about compatibility
