Change Log

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog and this project adheres to Semantic Versioning.

[0.1.0]

Changed

  • @charlesnicholson: flash commands no longer default to powering on the target.

[0.0.10]

Changed

  • @MarekNovakNXP: Fixed casting of swd_read32 to properly handle reading 32-bit register when MSB is set.
  • @sstallion: Fixed casting of swd_read8, and swd_read16 to properly handle reading 32-bit register when MSB is set.

[0.0.9]

Changed

  • @charlesnicholson: fixed non-deterministic crash on Linux when unloading DLL.

[0.0.8]

Changed

  • @eldonrivers: added support for 'nxp' name for kinetis/freescale chips

[0.0.7]

Added

[0.0.4]

Changed

  • When loading the SEGGER lib on Linux, os.walk is used to descend recursively through the directory tree.

Changed

  • Serial number no longer required command-line argument for command-line tool; if not specified, selects the first emulator.
  • Fixed bug in Linux library load where 32-bit DLL was loaded on 64-bit platform.

[0.0.2]

Added

  • Support added for writing to flash outside of flashing firmware:
    • flash_write
    • flash_write8
    • flash_write16
    • flash_write32
  • Added unlock method for unlocking a device connected to a J-Link instance.

Changed

  • Fixed logic for determine if J-Link is halted; SDK documentation implies that return value for JLINKARM_IsHalted() is <= 1, but example on Page 144 suggests otherwise; .halted() changed to reflect examples suggestion.
  • Fixed logic in .exec_command(). Since the J-Link SDK does not conform to the standard of returning zero only in cases of error, JLINKARM_ExecCommand may succeed, but still return a non-zero value. Checking the error string is the best way to handle this, and the return value should be ignored.
  • Fixed logic in handling the return value of JLINKARM_Connect(), JLINKARM_Connect() can return with a positive value which still indicates success.

[0.0.1d]

Changed

  • open() with serial_no=None and ip_addr=None will connect to the first USB device. This permits operation without having to define serial numbers for workflows using one emulator.

[0.0.1c]

Changed

  • reset() with halt=False would previously cause a mass erase of the device as it used JLINKARM_ResetNoHalt(); now uses JLINKARM_Reset() followed by a call to JLINKARM_Go(), and does not trigger a mass erase if the device is secure.

[0.0.1b]

Added

  • sync_firmware

Changed

  • Added a minimum version decorator to wrap functions that require at least a certain version of the J-Link software in order to be used.
  • Removed 'open_required()' for 'exec_command()', 'disable_dialog_boxes()', and 'enable_dialog_boxes()'.
  • Added a sample script for automated updates on Windows platforms.
