Differences between in port.c [FreeRTOS vs STM32CubeMX portings]
Hi,
The port.c file for the same FreeRTOS version [8.2.3] have a difference.
In the Official FreeRTOS release:
configPRESLEEPPROCESSING( xModifiableIdleTime );
configPOSTSLEEPPROCESSING( xExpectedIdleTime );
In the STM32CubeMX
configPRESLEEPPROCESSING( &xModifiableIdleTime );
configPOSTSLEEPPROCESSING( &xExpectedIdleTime );
Why this difference? It is wrong in the Cube?
Best Regards,

I could say as I’m not familiar with the ST code, however I would guess
it is either a mistake or otherwise it is not necessary.
configPRESLEEPPROCESSINIG() and configPOSTSLEEPPROCESSING() are both
macros, so the parameter passed in is accessed directly inline in the
code, not as a parameter would be in a function call. Therefore, if the
address of xModifiableIdleTime was needed you can put the ‘&’ on the
variable inside the macro, not when you pass the variable into the
macro. From a previous post it seems there are some issues in the
implementation of ST’s tickless idle code.
