Release v0.20.0 · pyocd/pyOCD

New features

pyOCD now supports managed CMSIS-Packs. A new pack subcommand has been added to the pyocd tool that lets you install packs to add target support with a single command. See #610 and the new target support documentation for details.
Target auto-detection is supported for STLinkV2-1 probes (those with a USB MSD volume containing an "mbed.htm" file), enabling the same ease of use provided by the DAPLink firmware.
SVD support is now built-in. Most built-in targets have SVD files integrated into pyOCD, and all pack targets should support SVD. The main use right now is through the commander, where you can show peripherals and read or write peripheral registers by name.
The gdbserver supports the range step command from gdb. This may improve step performance slightly.

Fixed a number of built-in targets where the flash algo was accidentally dropped from the flash region definition in the 0.19.0 release: lpc11xx_32, lpc11u24, lpc1768, lpc54114, lpc54608, lpc824, kl28z, stm32f429xx, stm32f439xx.
Adjusted Musca targets' memory map to work around chip errata.
Fixed page size and enabled double buffering for some built-in STM32 targets: stm32f412xx, stm32f429xx, stm32f439xx, stm32l031xx.

Logging more information about the DP and AP types and versions.
More changes to reduce the amount of libusb related log messages. Many debug messages were removed, and warnings about possible permissions issues are only logged once per device per process.
Added debug.log_flm_info user option to log debug messages with details of .FLM flash algorithms.
Commander show map command prints both sector and page sizes.
A universal wheel of pyOCD is now released to PyPI in addition to the source distribution.

Flash programming will not attempt to read data from flash regions that are marked as non-readable.
Fixed the get_probe_with_id() APIs on debug probes.
Correctly decoding the USB serial number for certain versions of STLinkV2 where the serial number is incorrectly encoded.
Catching additional errors that could be thrown by USB devices when checking to see if they provide a CMSIS-DAPv2 interface.
Commander savemem command inits the flash algo when accessing flash regions with is_powered_on_boot flash set to false.
High level flash erase operations, e.g. via pyocd erase, correctly deal with sector and page sizes being different.
Invalid CMSIS-Pack paths are handled gracefully with a warning log message, but pyOCD continues executing (unless the selected target type is in the missing pack, in which case you'll get an unknown target type error).
Removed websocket-client and future packages from requirements.

The most recently created Session instance is accessible via Session.get_current().
