| 1 # Openmoko's custom debug board for their Neo1973 and Neo FreeRunner | |
| 2 # smartphones is an important piece of history; to the best of my | |
| 3 # (Mychaela's) understanding, it was one of the first FT2232x devices | |
| 4 # to formalize the idea of having the kernel create only one ttyUSB | |
| 5 # device for Channel B (which is a standard UART), leaving Channel A | |
| 6 # untouched for userspace applications like OpenOCD. The feat is | |
| 7 # accomplished by giving the device a custom USB ID (the one used by | |
| 8 # OM for this debug board is 1457:5118), and teaching the ftdi_sio | |
| 9 # driver in the Linux kernel to create only one ttyUSB device for | |
| 10 # such USD IDs. | |
| 11 # | |
| 12 # What follows is a dump of the EEPROM made from the debug board which | |
| 13 # I got with my FreeRunner back in 2011; it appears to have a per-unit | |
| 14 # serial number string. The FTDI chip is FT2232D and the EEPROM is a 93C56. | |
