Jacek,
The problem is that the board only contains the following
parts:
(2) flash chips
(2) dram chips
(1) 140-pin connector
The data and address busses are each run directly to the
connector (no multiplexing, etc), so there are 32 address pins
32 data pins and 12 control lines. The design is extremely
simple; everything is just connected directly to the Strongarm
processor bus.
The simple test fixture I wanted to build is just a shift
register that would allow a PC program to shift out
the 76 bits serially and then latch them for accessing
the memory.
Although this is probably not what you were expecting,
thanks for the ideas and suggestions!
