Booting RTEMS/GeSys on a Motorola MVME23xx (PowerPC) Board

On the MVME23xx series boards, RTEMS/GeSys is booted using the Motorola PPCBug firmware (and part 2). First, you need to configure the firmware settings using the 'env' and 'NIOT' commands. The settings you want to look for are:

env

Network PReP-Boot Mode Enable [Y/N] = Y? Y

NIOT

BOOTP/RARP Request Control: Always/When-Needed (A/W)=A? A

My complete settings can be found here.

Once the correct settings have been entered, simply type the NBO command to initiate the boot process. There are several 'env' options for autostarting the board. Consult the PPCBug documentation.

Notes

• The VME windows should best be switched off to avoid conflicts during early boot. The VME windows are not used by the BSP since it now uses its own VME setup. The vme Universe chip is fully supported. (This is maybe different from what older README files for this BSP recommend.)
• The BSP has been patched to enable certain RTEMS/GeSys features to allow for supporting EPICS' 'devLib' on this BSP (address probing and VME).
• Contrary to what some console output lines might suggest, there is currently no way to pass a commandline (other than the BOOTP option 129) to the kernel.
• Booting RTEMS/GeSys using a vxBootrom is not supported.
