v0.5.1

Released: 2026-04-08

Fixed

• STM32 and other SWD-only boards failing to connect — rtt-helper.py now explicitly sets SWD interface and a safe default speed (4 MHz) before calling jlink.connect(). Without this, pylink defaulted to whatever the probe’s last interface state was (often JTAG), causing connect() to silently return a partial session that then failed at jlink.halted() with “Target is not connected”. Affects standalone J-Link probes connecting to STM32, NXP, and other Cortex-M targets. Nordic DKs with J-Link OB were unaffected since they only support SWD. (thanks @littleYangYu91, fixes #3)
• Unclear error when target connection fails — added explicit target_connected() check after connect() with a detailed error message listing possible causes (wrong device name, board not powered, SWD pins not wired)
• Tightened date column width — date column was leaving ~30px of empty space past the timestamp text when the date toggle was enabled. Reduced from 185px/220px to 155px/185px to match the rendered width
