- Diagnosing silent CPU fallback on RK3588 with RKNN PERF data
A Juejin article documents how to identify operators silently falling back from the RK3588 NPU to the CPU despite correct inference results. The author uses librknnrt's rknn_query(RKNN_QUERY_PERF_DETAIL) output, enabled with RKNN_FLAG_COLLECT_PERF_MASK, and classifies execution by CPU time share. On-device tests of YOLOv8n and YOLOv8s-seg were classified as NPU_ONLY, while the thresholds and broader conclusions remain the author's own methodology.

A developer built a runnable license-plate recognition pipeline in two days using YOLOv8n for detection, LPRNet with CTC decoding for text recognition, and HSV heuristics for plate color. The author reported 99% performance on CCPD, but real mobile-phone images exposed failures involving out-of-province plates, angled or distant shots, double-layer plates, screenshots, scans, and poor lighting. The article provides runnable code and recommends broader data, stronger augmentation, grouped evaluation, and a learned color classifier for production use.
