The MVME3100 is a VME board based on a PowerPC MPC8540 processor. It is supported with the MVME3100 BSP.


The MVME3100, one of the first VMEbus products with the system-on-chip MPC8540 processor, offers a growth path for VMEbus customers with applications on the previous generation of VME, specifically the MPC8240 and similar (MPC603 family) processors. The system-on-chip implementation offers power/thermal, reliability, and lifecycle advantages not typically found in alternative architectures. The faster processor and 2eSST VMEbus interface (the same as the MVME6100) combine to offer significant performance improvement.

New cost-effective peripherals can be integrated easily using USB and Serial ATA interfaces. SATA represents a significant cost reduction opportunity from older SCSI technology, with generally lower drive pricing for equivalent capacity.

Usage Notes

WARNING: It is extremely important that a MOTLoad "waitProbe", "netShut" sequence be executed before booting RTEMS. Otherwise, network interface interrupt handlers installed by MOTLoad may cause memory corruption
