v0.23.0

New features

• Added a connect_mode option. It can be set to one of halt, pre-reset, under-reset, attach. The default is halt, retaining previous behaviour. In particular, under-reset can often be used to connect to out of control targets.
• Watchpoints in v8-M targets work now, with added support for DWT version 2.
• Several additions to the commander:
  • go and halt report target state.
  • continue and c aliases for go.
  • load command to load any file, including hex or ELF. (loadmem only loads binary.)
  • fill command for filling memory with patterns.
  • find command to search for byte patterns in memory ranges.
  • watch, lswatch, and rmwatch commands for managing watchpoints.
  • Hex dumps now include an ASCII representation column.

Boards and targets

• New Cypress PSoC6 devices.
• Add NuMaker-M252KG board and M252KG6AE target.
• HDSC HC32F46X, HC32F120, and HC32M120 targets added.

Changes

• Removed halt_on_connect option in favour of the added connect_mode option. To get the behaviour of turning off halt_on_connect (the default was on), set connect_mode to attach.
• Tildes are expanded in ELF file paths.
• Description message included in exceptions raised for No ACK, SWD protocol error, or unrecognized CMSIS-DAP transfer response values.
• Explicitly denote support for Python 3.8.

Fixes

• Fixed bugs related to converting user options when set from the command line.
• Fixed show option in commander.
• Corrected an undefined attribute error if an invalid path to an ELF file is specified.
• Addressed concurrency issues with recent memory map changes. The target memory map is now deep copied for each session.
• Fix some minor deprecation warnings reported by Python 3.8.
