charset=UTF-8 Content-Transfer-Encoding: 8bit CRITICAL BUG FIX: debug_frames.insert('I', Vec::new()) was clearing the I-frame vector on every new I-frame, keeping only the last one. BEFORE: CSV collecting 1 I-frames (only last frame with loopIteration=1734) AFTER: CSV collecting 18 I-frames (all frames starting from loopIteration=0) RESULTS: - ✅ CSV now starts with correct loopIteration=0 and timestamp=62694011 - ✅ Collects all I-frames instead of just the last one - ✅ Proper sequential frame progression - ✅ Matches blackbox_decode initial frame structure IMPACT: Resolves major data corruption in CSV export where most I-frames were lost, causing plots to show incorrect gyro/motor data. --- src/main.rs | 3 --- 1 file changed, 3 deletions(-) diff --git a/src/main.rs b/src/main.rs index bf0bdca..01197fc 100644 --- a/src/main.rs +++ b/src/main.rs @@ -1717,9 +1717,6 @@ fn parse_frames( } } - // Initialize debug frame storage - debug_frames.insert('I', Vec::new());
