I was wondering how much more complete the Posix API is for RTEMS in version 5, compared to 4.10? In doing this port, should I be looking to switch rtems-specific code for Posix code? That should help in future upgrades, no?

Hi Sebastian,

     That makes sense; I believe the last port was to rtems 4.10. Such a guide would be very helpful. I'll take a look at the release page to see what I can find there.

Hi all,

   I'm slowly working my way through porting rtems5 to EPICS-3.15.6. THings have changed since the previous port, both in EPICS and RTEMS. I just hit an error concerning rtems malloc, in particular this type and the function which uses it, malloc_get_statistics().

this function was already removed in RTEMS 4.11:

Release/4.11 – RTEMS Project<https://devel.rtems.org/wiki/Release/4.11#APIRemovals>
The 4.11 dot point release details are: 4.11.0 (milestone:4.11.0) ; 4.11.1 (milestone:4.11.1) ; 4.11.2 (milestone:4.11.2) ; 4.11.3 (milestone:4.11.3) ; 4.11.4 ...

Is there a list of rtems functions somewhere so I can figure out what to replace these things with. There are plenty more to go, so knowing how to translate would be very useful.

The RTEMS 5.1 release page is a bit detailed. Maybe we should also add a section which covers potential update issues from previous RTEMS releases.
