bfd-stlink-interface

name	bfd-stlink-interface
description	Use when flashing, reading memory, writing memory, or starting debug sessions through ST-Link tools such as STM32_Programmer_CLI or ST-LINK_gdbserver, especially when J-Link-specific commands do not apply.

BFD ST-Link Interface

Use this skill for ST-Link-specific probe control. This skill is independent from J-Link and does not describe HSS flows.

Quick Start

python3 ./.codex/skills/bfd-project-init/scripts/bootstrap.py --project-root . --mode check

/opt/st/stm32cubeclt_1.19.0/STM32CubeProgrammer/bin/STM32_Programmer_CLI -l stlink

python3 BFD-Kit/skills/codex/bfd-flash-programmer/scripts/stlink_flash.py --firmware "${STM32_HEX}"

Core Commands

# Connect and identify target
STM32_Programmer_CLI -c port=SWD mode=UR reset=HWrst freq="${STM32_SPEED_KHZ}"

# Read memory
STM32_Programmer_CLI -c port=SWD mode=UR reset=HWrst freq="${STM32_SPEED_KHZ}" -r32 0x20000000 4

# Write memory
STM32_Programmer_CLI -c port=SWD mode=UR reset=HWrst freq="${STM32_SPEED_KHZ}" -w32 0x20000000 0x12345678 -nv

# Start ST-Link GDB server
ST-LINK_gdbserver -p 61234 -m 1

Hard Rules

• Use freq=<kHz> for STM32_Programmer_CLI SWD connections; do not use speed=<kHz>.
• Lock the probe by serial number when multiple ST-Links may be connected.
• Treat ST-Link memory access as polling/snapshot style access, not as an HSS-equivalent path.
• Keep ST-Link guidance separate from J-Link-only flows.
