SOC1B00 Block Diagram. Wonder about the Boot Initialization source Code for the board. And what's this CPLD ? (using CPLD for change to memory map at testing program...?)
what do you wonder about it? cpld stands for complex programmable logic device. it's a chip that you can program to act like some set of individual logic gates.
it looks like they use it for buffering the CF slot and decoding the chip selects on the memory; hence the bit about changing memory maps.
