# Openmoko's custom debug board for their Neo1973 and Neo FreeRunner # smartphones is an important piece of history; to the best of my # (Mychaela's) understanding, it was one of the first FT2232x devices # to formalize the idea of having the kernel create only one ttyUSB # device for Channel B (which is a standard UART), leaving Channel A # untouched for userspace applications like OpenOCD. The feat is # accomplished by giving the device a custom USB ID (the one used by # OM for this debug board is 1457:5118), and teaching the ftdi_sio # driver in the Linux kernel to create only one ttyUSB device for # such USD IDs. # # What follows is a dump of the EEPROM made from the debug board which # I got with my FreeRunner back in 2011; it appears to have a per-unit # serial number string. The FTDI chip is FT2232D and the EEPROM is a 93C56. 00: 0802 1457 5118 0500 3280 0000 0200 1296 10: 30A8 12D8 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 0312 004F 0070 0065 006E A0: 004D 006F 006B 006F 0330 0044 0065 0062 B0: 0075 0067 0020 0042 006F 0061 0072 0064 C0: 0020 0066 006F 0072 0020 004E 0065 006F D0: 0031 0039 0037 0033 0312 0046 0054 0053 E0: 0048 0044 004E 0032 004B 0000 0001 0000 F0: 0000 0000 0000 0000 0000 0000 0000 773F
