Version 2.0.0 in Progress

  • Fix packet scheduling from orbuculum
  • Move to semantic numbering - 2.00 becomes 2.0.0.
  • Various fixes in orbmortem for reliability and performance
  • Improve timing of orbuculum mux to ensure data get flushed to orbmortem on crash
  • Version bumped to 2.00 in Progress because of size and impact of changes
  • Addition of orbprofile for ETM profiling and integration with {k/q}cachegrind, see https://github.com/KDE/kcachegrind.
  • Addition of orbmortem for ETM/ETB post-mortem analysis.
  • Licenses updated to use SPDX identifiers...the license itself hasn't changed, we just lost a chunk of text at the head of every file, with the license now in the LICENSE file.
  • Orbtrace split off into separate repository
  • Split of orbuculum into the network server (orbuculum) and the fifo server (orbfifo).
  • Extensive changes to support orbtrace

3rd June 2022 (Version 1.13)

  • Fix -v missing parameter
  • Allow orbcat sockets to reconnect on loss of connection
  • Add SAM5X SWO support
  • Prevent segfault in orbtop when elf changes
  • Fix assert when fpga has no data to deliver
  • Add pyocd to list of trace sources *Complete fix for specified length integers on 32 bit platforms (Rasbian support)
  • Compatability with languages other than C family (specifically Rust)

23rd October 2020 (Version 1.10)

  • Replace master with main.
  • Single entry into a channel definition can be expanded multiple times (up to 4), so -c,z,"[%02x] %c" would print both a hex and ascii representation of a character, for example
  • Link Monitoring and reporting (enabled with the -m option to orbuculum.
  • Simple colour support (disable by commenting out SCREEN_HANDLING in the makefile).
  • Internal restructuring to simplify the packet decode. This will help you if you want to implement your own handlers. See orbcat.c for a simple example, or orbtop.c if timestamp ordering is important to you.
  • orbuculum now processes simple ISYNC messages, reporting them as type 8 in the hwevent fifo.
  • ocbcat can now read directly from a file.
  • orbcat and orbuculum can both terminate reading from a file when it's exhaused with the -e option.
  • Addition of JSON output for orbtop
  • Interrupt measurements have been added into orbtop
  • Per interval status reporting (overflow, sync etc) has been added to the orbtop interactive display.
  • povray splash screen generator
  • Refactoring of fifo code to allow it to be optional in orbuculum.c

9th September 2019 (Version 1.00)

  • Change to BSD from GPL License
  • Fixes to command line options, raw output and HW event decoding
  • Use of nextpnr-ice40 instead of arachne-pnr
  • Extensive changes to gdbtrace.init

14th August 2019 (Version 0.23)

  • Small edits to gdbtrace.init for tidying purposes
  • Fix integration time units in orbtop
  • Allow orbtop to gracefully restart when elf file is changed (e.g. on recompile)

13th August 2019 (Version 0.22 - no functional changes)

  • Makefile/Include path change to allow compilation on OpenSuse

5th August 2019 (Version 0.22)

  • Internal simplifications and tidying
  • Fix signal bug which could lead to orbuculum bailing when a client disconnected

4th August 2019 (Version 0.21)

  • gdbinit is changed to reference SWO rather than SWD (Issue #22)
  • Support for higher speed connections using linux kernels that support the BOTHER option.
  • Addition of C++ demangling support.
  • Specific gdbinit support for STM32F4
  • Small changes to support libftdi1.4 exclusively. It's essential you use this version of libftdi or higher!
