@qq20739111 thks, official community = github? https://github.com/radxa-docs/docs/ i asked claude to make a summary of my project with npu: We use the vendor's ACUITY toolkit inside a Docker container (ubuntu-npu:v2.0.10.1) to convert ONNX → quantized .nb files. - Pipeline: onnxsim → pegasus_import → pegasus_quantize → pegasus_export, uint8 quantization, deployed to ~/npu_models/ via push.sh. - Runtime: custom npu_server.c (pre-allocated input buffer, no per-call mmap) that the Python app talks to. - Hard lesson #1 — quantization: only pure Conv+BN+ReLU survives uint8. Attention, SE blocks, hard-swish, LayerNorm all collapse to constant outputs. So no MobileNetV3+, no transformers. - Hard lesson #2 — concurrency hang: NPU IRQs get lost when camera ISP DMA runs in parallel (shared memory bus). Fix: suppress GStreamer buffer copies during inference. Never STREAMOFF/ON the sunxi-vin driver — instant kernel crash. - Result: 12 models running (9 NPU + 3 CPU) at ~40ms/inference.

@chris178 im using this image ( r5 512 ) with the mem=4g param i tried the nick A image too, same problem. ( i tried the r4, r1, 512 and 4096 ) i didnt tried a different microsd, im going to buy a new one and make a new test maybe i got a faulty board. (im using npu and a lot of cpu, everything running fine) Srry about my poor english, is not my native language 😅

hello i have ths a7z with 8gb ram. Actualy im using with only 4gb (ok for my application). I can boot only if i set mem=4g. Any workaround for that? i tried all images ive found and no one can boot with 8gb.
