7.3.8: RTEMS Postdriver Callback

The postdriver_hook entry in the RTEMS CPU Configuration Table may be the address of a user provided routine that is invoked immediately after the the device drivers and MPCI are initialized. Interrupts and tasking are disabled. The postdriver hook is optional.

Although optional, most of the RTEMS BSPs provide a postdriver hook callback. This routine is usually called bsp_postdriver_hook and is found in the file:

c/src/lib/libbsp/CPU/BSP/startup/bsppost.c

The bsp_postdriver_hook() routine is the appropriate place to perform initialization that must be performed before the first task executes but requires that a device driver be initialized. The shared implementation of the postdriver hook opens the default standard in, out, and error files and associates them with /dev/console.
