2014-08-02drivers/jlink: fix SWD speed config, and set it before sending anythingPaul Fertser
During the initialisation a driver might need to communicate with the target (e.g. sending jtag2swd sequence), so when doing so it should honour the user-specified speed.

This is usable on most or all FTDI adapters using a small hardware tweak. TCK goes to SWCLK as expected. TDO should be wired to SWDIO. For TDI there are two options: Either add a 74HC126 or similar tri-state buffer between TDI and SWDIO, with OE controlled by a signal named SWDIO_OE. Or simply connect TDI and SWDIO together via a suitable resistor (220-470 ohms or so depending on the drive capability of the target and adapter). nSRST (and of course Vcc, GND) may be connected too but all other signals should be NC.

2014-03-29jlink: add support for Jlink-OB (0x0105) devicesAndrey Yurovsky
The JLink-OB (onboard) devices work the same way as the normal JLink except that their PID is 0x0105 (and that's the only one we know of so far) and their endpoint addresses are different due to there being a CDC-ACM interface as well. These JLink-OB devices show up on a lot of vendors' development kits as an integrated debugger. This change simply checks whether the adapter we opened has a JLink-OB PID and, if it does, uses the JLink-OB endpoints rather than the default. To do this, we add a new routine, jtag_libusb_get_pid() to the libusb adapter layer, it in turn just calls libusb_get_device_descriptor(), which previously had no wrapper. Also, checkpatch.pl doesn't like the VID/PID macros as defined so I moved them to the array itself. This should have no effect on the code. This change adds the 0102 through 0104 PIDs to openocd.rules as well as this new 0105 PID. Tested on an Atmel SAM4S Xplained board which has a JLink-OB, also regression tested by using a 0x0101 PID normal JLink adapter.

2014-03-17All Atmel-provided CMSIS-DAP devices use 512 byte packet sizeJörg Wunsch
The existing CMSIS-DAP driver matches the USB VID/PID against 0x3eb (Atmel VID) and 0x2111 (Atmel EDBG embedded CMSIS-DAP debugger), and then bumps the packet size from its default of 64 to 512. However, it turned out that *all* Atmel-provided CMSIS-DAP devices (EDBG with PID 0x2111; JTAGICE3 with firmware version 3.x, PID 0x2140; new Atmel-ICE [successor of JTAGICE3], PID 0x2141) require a 512-byte packet size. Obviously, all run the same USB implementation inside their custom microcontroller. Thus, it seems best to simply assume that *all* Atmel CMSIS-DAP devices use this packet size, and don't check the PID at all.

The new version of STLink (V2-1) has a different USB endpoint layout. As the PID of the device also changed it's possible to change EPs used by OpenOCD in runtime. The patch adds three new fields to stlink_usb_handle_s and assigns right EP numbers in stlink_usb_open(). Parts of the code inspired by and used with consent of Jens Hoffmann.

2014-03-07stlink: Use callback to increase frequency of trace data samplingAndreas Fritiofson
The ST-LINK/V2 has limited internal buffering, such that trace data can be missed if the target is generating data at a rate quicker than the OpenOCD trace sampling. The issue of lost data is compounded since individual TPIU packets may be split across individual STLINK_TRACE_EP reads, and misleading results can occur if mid-packet loss occurs. This patch increases the frequency of checking for pending trace data with the aim of minimising such losses. Note: With the limited (I/O and memory) bandwidth of the ST-LINK/V2 there cannot, however, be a guarantee against trace data loss. The timer callback is only added when enabling tracing, and is removed when tracing is disabled. Change-Id: Ibde9794b77793d3068f88cb5c1a26f9ceadcbd8a Signed-off-by: James G.

2014-02-24drivers/jtag: usb_blaster: make command handlers more strictAntony Pavlov
If user used wrong argument number for some usb_blaster_* commands then openocd show just warning message. This commit makes command handler's behaviour more strict and openocd treats wrong argument number as an error. In addition we already have 'help' and 'usage' information in struct command_registration ublast_command_handlers[], so we can drop redundancy messages in command handlers.

2014-02-24tcl/drscan: handle invalid syntax with a conditional, not assertPaul Fertser
When "drscan" command is used improperly, such as in: drscan stm32f1x.cpu -endstate drpause there're no fields to scan, and so the assert leads to a segfault. This should be treated like any other syntax error instead.

2014-02-24drivers/ftdi: warn the user if he tries to use undefined reset signalsPaul Fertser
It is really an error to try to use a reset_config that doesn't match adapter's capabilities, however OpenOCD has no way to specify them. Using wrong reset_config might lead to very confusing behaviour, so I think LOG_ERROR is justified here.
