Improve J-Link driver and introduce libjaylink.

2015-11-26T12:19:22Z

This patch uses libjaylink which is a library to access J-Link devices. As other tools which are not in the scope of OpenOCD also need to access J-Link devices a library is used. A firmware upgrade tool and an advanced configuration tool for J-Link devices are under development. Further versions of libjaylink will support additional features OpenOCD could benefit from. This includes TCP/IP as additional possibility to connect to J-Link devices as well as power tracing and device internal communication. The latter is used to access peripherals on some development boards (e.g EFM32 STK and DVK). Integration of libjaylink is realized with a git submodule like jimtcl. As libjaylink depends on libusb-1.0 only, no additional dependency is introduced for OpenOCD. All low-level JTAG and SWD implementations of the current driver are left untouched and therefore no incompabilities are to be expected. Improvements of this patch: * Support for more USB Product IDs, including those with the new scheme (0x10xx). The corresponding udev rules are also updated. * Device selection with serial number and USB address. * Adaptive clocking is now correctly implemented and only usable for devices with the corresponding capability. * The target power supply can now be switched without the need for changing configuration and power cycling the device. * Device configuration is more restrictive and only allowed if the required capabilities are available. * Device configuration now shows the changes between the current configuration of the device and the values that will be applied. * Device configuration is verified after it is written to the device exactly as the vendor software does. * Connection registration is now handled properly and checks if the maximum number of connections on a device is reached. This is also necessary for devices which are attached via USB to OpenOCD as some device models also support connections on TCP/IP. * Serial Wire Output (SWO) can now be captured. This feature is not documented by SEGGER however it is completely supported by libjaylink. This patch and libjaylink were tested on Ubuntu 14.04 (i386), Debian 7 (amd64), FreeBSD 10.0 (amd64) and Windows XP SP3 (32-bit) with the following device and target configurations: * JTAG: J-Link v8.0, v9.0 and v9.3 with AT91SAM7S256 * SWD: SiLabs EFM32 STK 3700 (EFM32GG990F1024) * SWD: J-Link v8.0, v9.0 and v9.3 with EFM32GG990F1024 * SWD: XMC 2Go (XMC1100) * SWD: XMC1100 Boot Kit (XMC1100) * SWD: IAR Systems / Olimex Eval Board (LPC1343F) * SWD: Nordic Semiconductor nRF51 Dongle (nRF51422) * SWD: SiLabs EZR32 WSTK 6220A (EZR32WG330FG60G) Except for Windows XP all builds are tested with Clang in addition to GCC. This patch and libjaylink are not tested on OSX yet.

at91samd: handle reset run/halt in DSU

2015-11-20T18:26:05Z

Atmel introduced a "Device Service Unit" (DSU) that holds the CPU in reset if TCK is low when srst (RESET_N) is deasserted. Function is similar to SMAP in ATSAM4L, see http://openocd.zylin.com/2604 Atmel's EDBG adapter handles DSU reset correctly without this change. An ordinary SWD adapter leaves TCK in its default state, low. So without this change any use of sysresetreq or srst locks the chip in reset state until power is cycled. A new function dsu_reset_deassert is called as reset-deassert-post event handler. It optionally prepares reset vector catch and DSU reset is released then. Additionally SWD clock comment is fixed in at91samdXX.cfg and clock is lowered a bit to ensure a margin for RC oscillator frequency deviation. adapter_nsrst_delay 100 is commented out because is no more necessary after http://openocd.zylin.com/2601 Change-Id: I42e99b1b245f766616c0a0d939f60612c29bd16c Signed-off-by: Tomas Vanek Reviewed-on: http://openocd.zylin.com/2778 Tested-by: jenkins Reviewed-by: Spencer Oliver

flash: New driver for XMC4xxx microcontroller family

2015-11-11T12:08:35Z

This is a complete flash driver for the Infineon XMC4xxx family of microcontrollers, based on the TMS570 driver by Andrey Yurovsky. The driver attempts to discover the particular variant of MCU via a combination of the SCU register (to determine if this is indeed an XMC4xxx part) and the FLASH0_ID register (to determine the variant). If this fails, the driver will not load. The driver has been added to the README and documentation. Tests: * Hardware: XMC4500 (XMC4500_relax), XMC4200 (XMC4200 enterprise) * SWD + JTAG * Binary: 144k, 1M Note: * Flash protect only partly tested. These parts only allow the flash protection registers (UCB) to be written 4 times total, and my devkits have run out of uses (more on the way) Future Work: * User 1/2(permalock) locking support via custom command * In-memory flash loader bootstrap (flashing is rather slow...)

flash: driver for Atmel SAMV, SAMS, and SAME

2015-11-10T20:27:09Z

This is a driver for the Atmel Cortex-M7 SAMV, SAMS, and SAME. I started with the at91sam4.c driver and then restructured it significantly to try to simplify it and limit the functionality to just a flash driver, as well as to comply with the style guide.

This makes it easier to relocate the install tree of OpenOCD from where it was originally built (for example, if put onto a different machine), without having to change scripts or add something to the command line every time.
