44 | | There's a bug that likely occurs in mvme2300-2700 prior to RTEMS 4.9. A call in libbsp/powerpc/shared/console/reboot.c attempted to board reset via the keyboard port. This resulted in a NOOP (i.e., nothing happened and the board did not reset). [https://www.rtems.org/bugzilla/show_bug.cgi?id=1362 PR1362] with a proposed patch which sets bit 1, port 0x92. This successfully resets *only* the board and I've also verified it does not reset the VME bus as described below. |
