# There exists a tentative plan in FreeCalypso queendom to produce a buffered # JTAG adapter design, tentatively named FreeCalypso JTAGbuf. It is envisioned # as being an FT2232H-based adapter (the previous plan was FT2232D, but that # chip is now NRND, and the Calypso chip's maximum JTAG TCK frequency of 10 MHz # can be achieved only with FT2232H) with LVC buffers between the FTDI chip's # fickle I/O pins and the JTAG target connection interface. # # The present EEPROM configuration is intended for this planned future # FreeCalypso JTAGbuf adapter; it is vaporware, but the present config source # file takes the place of much older (also vaporware) fc-jtag config that went # back to the beginning of freecalypso-hwlab Hg repository. vid 0x0403 # FTDI pid 0x7151 # Allocated by FTDI to Falconia Partners LLC manuf FreeCalypso product Buffered JTAG Adapter # Try to be nice to Weendoze lusers (or should it be Losedows?) byte00 0x00 # Channel A driver: D2XX byte01 0x08 # Channel B driver: VCP
