# The original Flyswatter (aka Flyswatter1) by TinCanTools is an # FT2232D-based buffered JTAG + UART adapter. It has a 93C56 EEPROM # in which a custom set of textual ID strings have been programmed, # but the USB ID is still 0403:6010 (FT2232x default and signifying # a dual UART), causing the bogosity whereby the Linux kernel creates # two ttyUSB devices for both FT2232D channels, for the first out of # that pair to subsequently disappear when OpenOCD runs and starts # accessing Channel A for MPSSE JTAG via libusb. # # What follows is a dump of the EEPROM made from the FS1 board I managed # to score on ebay; given that the serial number string is set to "FS000000", # I am going to assume that the factory programming was the same on all # units, without unique serial numbers. 00: 0000 0403 6010 0500 6480 0008 0200 1896 10: 16AE 12C4 0056 0000 0000 0000 0000 0000 20: 0000 0000 0000 0000 0000 0000 0000 0000 30: 0000 0000 0000 0000 0000 0000 0000 0000 40: 0000 0000 0000 0000 0000 0000 0000 0000 50: 0000 0000 0000 0000 0000 0000 0000 0000 60: 0000 0000 0000 0000 0000 0000 0000 0000 70: 0000 0000 0000 0000 0000 0000 0000 0000 80: 0000 0000 0000 0000 0000 0000 0000 0000 90: 0000 0000 0000 0318 0054 0069 006E 0043 A0: 0061 006E 0054 006F 006F 006C 0073 0316 B0: 0046 006C 0079 0073 0077 0061 0074 0074 C0: 0065 0072 0312 0046 0053 0030 0030 0030 D0: 0030 0030 0030 0302 0000 0000 0000 0000 E0: 0000 0000 0000 0000 0000 0000 0000 0000 F0: 0000 0000 0000 0000 0000 0000 0000 8317
