before i use the rtems , i just write the bare-metal code.
now i want to use the rtems. but i do not know how to add the original
bare-metal interrupt routine into the rtems program.
is it has conflict betweent the bare-metal code and the rtems code?
I has no idea about how to use my old code

sorry . i am also confused about this two things . because i find that when i
config the rtems kernel ,there is a option which is --enable posix.

"The system initialization API is available via‘‘#included‘‘."

i google the posix .now i know that posix is the abbreviation of "the Portable
Operating System Interface" it is for software compatibility with variants of
Unix and other operating systems
but you said, "POSIX and the Classic API are both C APIs."
than i think the posix is packaged on the basis
thanks a lot .
i have another question , if i use the smp, can i use the interrupt of rtems?
which i want to interrupt period of hard real time of 125us.
i do not know the difference of the bare-metal interrupt and the rtems
interrupt . is the rtems interrupt have performance loss of the h

Smp support first was usable in the 4.11 release series. It matured between
then and the git master which will be RTEMS 5. For new projects, we
recommend just using the git master and moving to the 5.x releases when
made. The smp has significant improvements and optimizations.

Setjmp and longjmp are part of the C Library and should be available on all
architectures supported by RTEMS

Hi all,
Does anyone know if the RTEMS C API provide some functionality similar
to the setjmp/longjmp functions of the POSIX API? I did a quick search
trough the official RTEMS C API doc, but at first glance I did not find
anything like that.
We are trying to implementing something as the C++ try/

Hi, I have 2 Questions about RTEMS!
1. What is the relationship between shell prompt and unlimited_object?
When I using RTEMS 4.11.2, I need 'CONFIGURE_UNLIMITED_OBJECTS' to use
shell prompt.
I already read 'RTEMS C User Manual - 24.7. Unlimited Objects ' page,
but I don't understand exactl
