4.4.1: Using the bit_rtems script

The simplest way to build RTEMS is to use the bit_rtems script. This script interprets the settings in the user.cfg file to enable or disable the various RTEMS options.

This script is invoked as follows:

./bit_rtems CPU [BSP]

Where CPU is one of the RTEMS supported CPU families from the following list:

• hppa1.1
• i386
• i386-elf
• i386-go32
• i960
• m68k
• mips64orion
• powerpc
• sh
• sparc

BSP is a supported BSP for the selected CPU family. The list of supported BSPs may be found in the file tools/rtems-4.0.0/README.configure in the RTEMS source tree. If the BSP parameter is not specified, then all supported BSPs for the selected CPU family will be built.

NOTE: The POSIX API must be enabled to use GNAT/RTEMS.
