BF.x are the pins of BlackFin, [x] is the BlackFin pins direction, LT.x are the pins of the LaTtice CPLD, FP.x the pins of the Altera FPga, LH1.x those of the Logic Analyser Header 1 (the 40 pins one), FLR.x those of the Spansion FLash Ram and USB.x the pins of the Philips ISP1362 USB On-The-Go controller. All the components above share the same 16-bits data bus and the 21-bit Address bus; the BlackFin address bus is 19-bits wide, the address bus width of the CPLD, the FPGA and the Logic Analyser is 8-bits and the USB chip is controlled by the two lower address bus lines.
Programming connector
Looks like the default Blackfin Connector. Tests are outstanding.
