MVME2500 Installation and Use (6806800L01H)

Factory Pre-Programming - Programming the SPI Flash usually takes a while. Ideally, the
SPI Flash should be pre-programmed in the factory before shipment.
ICT Programming - This programming is done on exposed test points using a bed of nails
tester.
4.6.3 Firmware Redundancy
The MVME2500 uses two physically separate boot devices to provide boot firmware
redundancy. Although the P20x0 provides four SPI Bus chip-selects, the P20x0 is only capable
of booting from the SPI Device controlled by Chip Select 0. External SPI multiplexing logic is
implemented on the MVME2500 to accomodate this chipset limitation.
The board power should be switched on before programming. The switch S2-8 should also be
powered on to successfully detect the SPI Flash chip.
