configure/os/CONFIG_SITE.<host_architecture>.Common
file specifies the target
architectures and board support packages to be supported.
For example, I regularly build for a single target:
CROSS_COMPILER_TARGET_ARCHS=RTEMS-mvme2100If you want to build for multiple RTEMS targets you would change this line to something like
CROSS_COMPILER_TARGET_ARCHS=RTEMS-mvme2100 RTEMS-uC5282 RTEMS-pc386The format of the target architecture names is RTEMS-bspname, where RTEMS- indicates that the RTEMS development tools and libraries should be used, and bspname is the name of the RTEMS target architecture and board support package used back in section 2.4.4.
