portNVIC_PENDSVSET / portNVIC_PENDSVSET_BIT duplicity on v9.0.0 ARM GCC ports

Posted by philpem on January 27, 2017

Hi, I'm currently trying to repeat my effort of porting the ARM CM3 MPU port of FreeRTOS to work with both FreeRTOS 9 and the Cortex-M4F (it was last used with FreeRTOS 7.5 on a Cortex M3 chip, so I'm redoing the port).

As part of that, I noticed that portmacro.h in most of the Cortex-M ports defines portENDSWITCHINGISR in a way which uses the value portNVICPENDSVSET, which isn't defined anywhere, but portNVICPENDSVSET_BIT is.

Is this intentional? Should portENDSWITCHINGISR be referring to portNVICPENDSVSETBIT as portYIELD and portYIELDWITHINAPI do?

Thanks, Phil.

Just noticed my explanation in the opening paragraph of that post is a bit rubbish: to clarify, I'm modifying the Cortex-M4F-MPU port of FreeRTOS so that it compiles with IAR.

And I've answered my own question -- looks like it was a bug, fixed on trunk but not yet released: https://sourceforge.net/p/freertos/code/2467/#diff-14

Best kind of support request ;o)
