Flash Bank Selection (J6)
The CPX750HA base board has provision for 1MB of 16-bit flash
memory. The RAM300 memory mezzanine accommodates 4MB or 8MB
of additional 64-bit flash memory.
The flash memory is organized in either one or two banks, each bank either
16- or 64-bits wide. Bank B contains the onboard debugger, PPCBug.
To enable flash bank A (4MB or 8MB of firmware resident on soldered-in
devices on the RAM300 mezzanine), place a jumper across header J6 pins
1 and 2. To enable flash bank B (1MB of firmware located in sockets on
the base board), place a jumper across header J6 pins 2 and 3.
