Previously, when doing EMU_CMD_HW_JTAG3 commands we would do two reads,
one to read the data, and one to read the result. However, we can just
do a single larger read instead.
The motivation for this change is a weird problem. If I run the Segger
software before running OpenOCD, then the first read always fails:
Error: usb_bulk_read failed (requested=1, result=0)
Error: jlink_tap_execute, wrong result -107 (expected 1)
Sniffing the USB traffic shows that the J-Link is returning an
overflow error, meaning it is expecting to return the full result
in a single read.

Error was:
checking for library containing FT_GetLibraryVersion... no
configure: error: You appear to be missing the FTD2xx driver library.
Reason were two cases:
Case one:
The FTD2xx library uses clock_gettime() and in normal cases
the linker will find the function in the libc library. Most
(older) systems require the program be linked with the librt
library to use these (see man clock_gettime: Link with -lrt).
Case two:
You can rebuild the FTD2xx library (relink from the object
files) against the primary (system wide installed) libusb-1.0.
So you avoid mixed code (GPL with proprietary code) in the
FTD2xx library. In this case, the FTD2xx library provides no
private (linked in) libusb-1.0 functionality and require the
program be linked with the libftd2xx __AND__ the libusb-1.0
to resolve all the libusb-1.0 symbols.

An alternative approach to show how much cleaner the pure pkg-config
way is.

making them depend on pkg-config being properly installed and
configured, including the necessary build host configuration for the
cross-builds (see

It should make it possible to compile OpenOCD without changes and
extra effort on GNU/Linux, FreeBSD users would need to supply a .pc

This is an attempt to bring the README files in line with the current
status of the OpenOCD development.
- remove some obsolete information and duplicated instructions
- reword some statements
- restructure in a way more appealing to a regular user
- add a supported hardware list to allow a potential user to determine
if his/her usecase is covered by a freetext keyword search through
the document
- Add OSX notes (courtesy GrizzlyAdams and inca)
Since most ftdi-based adapters are now covered by the ftdi driver, I
think it's ok to remove some of the libftdi/ftd2xx instructions, the
few users who still need them should refer to upstream docs instead.
I'm not sure if README.Windows should come with the DOS line endings,
but i'd expect many windows users to use their silly notepad to view
it, and notepad ignores LF apparently. (Decided to use LF anyway.)
I understand discussing and reviewing such a massive README change is
a somewhat demanding task but I feel it's a necessity to move forward
