v2.02.04 - 2026-03-11

Changes

• Correct udev rules in README by @rgrr in #185
• Hunting bugs and other features ;-) by @rgrr in #187
• RTT state machine by @rgrr in #191

Full Changelog: v2.02.03...v2.02.04

v2.02.03 - 2026-02-12

ATTENTION AGAIN

New release due to problems with TinyUSB.

• release binaries are built (again) with gcc
• CDC special functions via bitrate setting
  • 1200bit/s -> boot into BOOTSEL
  • 2400bit/s -> reboot probe
• minor optimizations in internal SWD communication

Note: there is an obscure bug in TinyUSB, see hathach/tinyusb#3495. Do not go later than 0.20.0.

Still investigating several issues concerning SWD sequences for RP2040/RP2350.

Full Changelog: v2.02.02...v2.02.03

v2.02.02 - 2026-02-09

ATTENTION

This is just a binary release because the pico (RP2040) binaries do not work if compiled with clang.

v2.02.01 - 2026-02-02

Misc

• Feature/176 increase xosc startup delay by @rgrr in #177

Full Changelog: v2.02.00...v2.02.01

v2.02.00 - 2026-01-20

Misc

• version bump to make it probe-rs compatible (again), see #163
• RP2350: get external flash size in #138
• nRF54Lxx support in #153
• enhanced SWCLK handling in #159
• experimental: RTT while debugging for pyocd in #165, #166, #167
• updates
  • FreeRTOS update
  • SDK2.2.0 compatibility
  • TinyUSB 0.20.0 ready (requires update in SDK)
• clang compilation works with SDK2 (but the SDK needs a patch ;-), see raspberrypi/pico-sdk#2700)
• minor fixes & cleanup

Full Changelog: v1.24...v2.02.00

v1.24 - 2025-02-27

SDK2.1.1 & RP2350

• RP2350 as a debug target by @rgrr: drag-n-drop in #129, RTT in #127
• RP2350 as probe HW by @rgrr in #124 and #126
• SDK2.1.1 compatibility by @rgrr in #118
• DAP server packet size settable via runtime configuration ("dap_psize/dap_pcnt")
• pyocd is again at DAP_PACKET_SIZE=128 and DAP_PACKET_CNT=1

Full Changelog: v1.21...v1.24

Bugs:

• clang compilation is broken since SDK2

v1.21 - 2024-08-06

RTT & misc

• corrected RTT (and SysView), see #117
• changed CMSIS-DAP packet size for pyocd to 512, see #112 and #116
• minor things

Full Changelog: v1.20...v1.21

v1.20 - 2024-02-05

Misc + probe-rs

• update CMSIS-DAP to 2.1.2, see #39
• nickname for probe, see #81
• hardware reset, see #93
• OpenOCD 0.12 no longer works with 1024 bytes packet size, thus OpenOCD packet size reduced to 512
• first attempts with probe-rs: requires rtt=0 in the configuration - probe-rs 0.23.0 solves the problem, so upgrade probe-rs!
• internal: moved CMSIS-DAP code away from main

v1.18

Misc

• NEW: ncm_device has been completely rewritten, see lwIP notes for more information
• NEW: configuration parameter r_start / r_end - RAM start/end for generic target to override default 0x20000000..0x20040000
• enhanced RTT control block search
• updated FreeRTOS to main
• probe can send its debug output to CDC/UART/RTT. The later cases are useful for debugging the probe
• build
  • compiles now with LLVM Embedded Toolchain for Arm
  • release build for pico/pico_probe with clang and link time optimization
  • new make targets to build a debuggee probe (and the corresponding debugger probe)
• bugfix
  • for generic target devices
  • several minor RTT fixes

v1.17

Persistent Runtime Configuration

What's Changed:

• Added carriage return to end of debug prints by @tornupnegatives in #66
• Configuration storage and parameterization by @rgrr in #69, documentation see here
• Build failure by @rgrr in #70
