Detailed Description

JTAG adapters based on the FT2232 full and high speed USB parts are popular low cost JTAG debug solutions.

Many FT2232 based JTAG adapters are discrete, but development boards may integrate them as alternatives to more capable (and expensive) third party JTAG pods.

JTAG uses only one of the two communications channels ("MPSSE engines") on these devices. Adapters based on FT4232 parts have four ports/channels (A/B/C/D), instead of just two (A/B).

Especially on development boards integrating one of these chips (as opposed to discrete pods/dongles), the additional channels can be used for a variety of purposes, but OpenOCD only uses one channel at a time.

As a USB-to-serial adapter for the target's console UART ... which may be able to support ROM boot loaders that load initial firmware images to flash (or SRAM).

On systems which support ARM's SWD in addition to JTAG, or instead of it, that second port can be used for reading SWV/SWO trace data.

Additional JTAG links, e.g. to a CPLD or * FPGA.

FT2232 based JTAG adapters are "dumb" not "smart", because most JTAG request/response interactions involve round trips over the USB link. A "smart" JTAG adapter has intelligence close to the scan chain, so it can for example poll quickly for a status change (usually taking on the order of microseconds not milliseconds) before beginning a queued transaction which require the previous one to have completed.

There are dozens of adapters of this type, differing in details which this driver needs to understand. Those "layout" details are required as part of FT2232 driver configuration.

This code uses information contained in the MPSSE specification which was found here: http://www.ftdichip.com/Documents/AppNotes/AN2232C-01_MPSSE_Cmnd.pdf Hereafter this is called the "MPSSE Spec".

The datasheet for the ftdichip.com's FT2232D part is here: http://www.ftdichip.com/Documents/DataSheets/DS_FT2232D.pdf

Also note the issue with code 0x4b (clock data to TMS) noted in http://developer.intra2net.com/mailarchive/html/libftdi/2009/msg00292.html which can affect longer JTAG state paths.

static

Clocks out bit_count bits on the TMS line, starting with the least significant bit of tms_bits and progressing to more significant bits.

Rigorous state transition logging is done here via tap_set_state().

Parameters

mpsse_cmd	One of the MPSSE TMS oriented commands such as 0x4b or 0x6b. See the MPSSE spec referenced above for their functionality. The MPSSE command "Clock Data to TMS/CS Pin (no Read)" is often used for this, 0x4b.
tms_bits	Holds the sequence of bits to send.
tms_count	Tells how many bits in the sequence.
tdi_bit	A single bit to pass on to TDI before the first TCK cycle and held static for the duration of TMS clocking.

See the MPSSE spec referenced above.

Function ft2232_add_pathmove moves the TAP controller from the current state to a new state through the given path, where path is an array of tap_state_t's.

Parameters

path	is an array of tap_stat_t which gives the states to traverse through ending with the last state at path[num_states-1]
num_states	is the count of state steps to move through
