Most RKNN conversion failures trace to toolchain/driver version mismatch. Align versions first, then argue about the model. Version matching is the first gate Version triangle: PC rknn-toolkit2, on-device rknn_server/runtime and the kernel RKNPU driver must be mutually compatible; Operator check: read the verbose build output to confirm nothing falls back to CPU; Output alignment: RKNN […]
Most people get stuck at “installed but won’t transcode”. On RK3588 the fix is almost always one of three setup decisions made at the start. Three things before you deploy Use the official Debian 11/12 image: its kernel ships the rkmpp decode driver. Ubuntu/Armbian also work; avoid heavily stripped third-party builds; Deploy via the official […]
