32 * JTAG adapters based on the FT2232 full and high speed USB parts are
33 * popular low cost JTAG debug solutions. Many FT2232 based JTAG adapters
34 * are discrete, but development boards may integrate them as alternatives
35 * to more capable (and expensive) third party JTAG pods.
37 * JTAG uses only one of the two communications channels ("MPSSE engines")
38 * on these devices. Adapters based on FT4232 parts have four ports/channels
39 * (A/B/C/D), instead of just two (A/B).
41 * Especially on development boards integrating one of these chips (as
42 * opposed to discrete pods/dongles), the additional channels can be used
43 * for a variety of purposes, but OpenOCD only uses one channel at a time.
45 * - As a USB-to-serial adapter for the target's console UART ...
46 * which may be able to support ROM boot loaders that load initial
47 * firmware images to flash (or SRAM).
49 * - On systems which support ARM's SWD in addition to JTAG, or instead
50 * of it, that second port can be used for reading SWV/SWO trace data.
52 * - Additional JTAG links, e.g. to a CPLD or * FPGA.
54 * FT2232 based JTAG adapters are "dumb" not "smart", because most JTAG
55 * request/response interactions involve round trips over the USB link.
56 * A "smart" JTAG adapter has intelligence close to the scan chain, so it
57 * can for example poll quickly for a status change (usually taking on the
58 * order of microseconds not milliseconds) before beginning a queued
59 * transaction which require the previous one to have completed.
61 * There are dozens of adapters of this type, differing in details which
62 * this driver needs to understand. Those "layout" details are required
63 * as part of FT2232 driver configuration.
65 * This code uses information contained in the MPSSE specification which was
67 * http://www.ftdichip.com/Documents/AppNotes/AN2232C-01_MPSSE_Cmnd.pdf
68 * Hereafter this is called the "MPSSE Spec".
70 * The datasheet for the ftdichip.com's FT2232D part is here:
71 * http://www.ftdichip.com/Documents/DataSheets/DS_FT2232D.pdf
73 * Also note the issue with code 0x4b (clock data to TMS) noted in
74 * http://developer.intra2net.com/mailarchive/html/libftdi/2009/msg00292.html
75 * which can affect longer JTAG state paths.
