2012-08-29server: warn if user changes server port after initSpencer Oliver
So the user can view the current port number these cmds were changed to COMMAND_ANY. However this means that the user can also attempt to change the port number after init, even though this is not supported. Issue a warning that this is not supported.

2012-08-29ftdi: fix overflow if last field of a scan is emptyAndreas Fritiofson
The last bit of a scan is clocked during TAP movement so it's necessary for the last field to have at least one bit. Strip trailing empty fields and make sure the TAP is not affected if there's nothing to scan. Clients probably shouldn't add empty fields so add a debug message to be able to track and fix them.

2012-08-29arm7_9: Fix broken halfword/byte memory readsAndreas Fritiofson
Always scan out all bits, but make sure only the allowed number of bytes end up in the caller-provided buffer. Discard the rest by adding another scan field when size < 4. Rewrite the endianness callback to avoid reading outside allocated memory. Make it directly usable as a callback without the need for a wrapper. Move the shared callback to a more suitable home in arm7_9_common. This fixes the regressions introduced in commits 991ed5a2b657e660f744eefddb084724e52938ea cb90d32e386a7489d31136997209c61e9559ff5e and c3074f377c1da33ca8ba8493826e1b52351eebc6 Change-Id: Ia8bde8c5a9844e89a1d6c0bc8534cd26f02f8d11 Signed-off-by: Andreas Fritiofson <andreas.fritiofson@gmail.com> Reviewed-on: http://openocd.zylin.com/789 Tested-by: jenkins Reviewed-by: Spencer Oliver <spen@spen-soft.co.uk> Reviewed-by: Freddie Chopin <freddie.chopin@gmail.com>

For odd byte counts, stm32x_write() pads the last byte and writes it using a discrete 16-bit access. The stlink debugger can't issue 16-bit writes so it fails for odd byte writes. This patch changes stm32x_write() to pad odd byte writes into a new buffer and use the normal code path with a single block write. The fallback path, when working area cannot be allocated, has to use 16-bit writes though which means that sufficient working area is required for stlink and odd byte writes.

2012-07-17Add FTDI JTAG driver using MPSSE layerAndreas Fritiofson
Based on ft2232.c but uses the MPSSE layer for low-level access, greatly simplifying the JTAG logic. Remove all libftdi/FTD2XX code and all layout specific code. Layout specifications are instead handled in Tcl. Use a signal abstraction to enable Tcl configuration files to define outputs for one or several FTDI GPIO. These outputs can then be controlled using the ftdi_set_signal command. Special signal names are reserved for nTRST, nSRST and LED (for blink) so that they, if defined, will be used for their customary purpose. Depending on the type of buffer attached to the FTDI GPIO, the outputs have to be controlled differently. In order to support tristateable signals such as nSRST, both a data GPIO and an output-enable GPIO can be specified for each signal. The following output buffer configurations are supported: * Push-pull with one FTDI output as (non-)inverted data line * Open drain with one FTDI output as (non-)inverted output-enable * Tristate with one FTDI output as (non-)inverted data line and another FTDI output as (non-)inverted output-enable * Unbuffered, using the FTDI GPIO as a tristate output directly by switching data and direction as necessary The data and output-enables are specified as 16-bit bitmasks, corresponding to the concatenation of the high and low FTDI GPIO registers. To specify an unbuffered output, use the same bitmask for both data and output-enable. The adapter configuration file must also specify default values for the FTDI data and direction GPIO registers, and the channel being used (if different from 0).

2012-07-17Add MPSSE communications layer for FTDI chipsAndreas Fritiofson
This is a higher-level libftdi replacement for use when implementing protocol drivers for FT2232, FT2232H or FT4232H. It takes care of device open/close and, unlike libftdi, also MPSSE command abstraction, command queueing, buffer handling and return data parsing. The FTDI device is accessed through libusb-1.0 in asynchronous mode.
