|
|
* 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.
