# Physical acceptance test
|
|||
|
|
|
|||
|
|
The image has passed structural checks. Run this checklist on the RK1 attached
|
|||
|
|
to the actual carrier and TV before treating it as the permanent media center.
|
|||
|
|
|
|||
|
|
## 1. Provisioning and services
|
|||
|
|
|
|||
|
|
SSH over Ethernet and wait for provisioning to finish:
|
|||
|
|
|
|||
|
|
```bash
|
|||
|
|
ssh rkadmin@rk1-media.local
|
|||
|
|
sudo systemctl is-active rk1-media-identity.service
|
|||
|
|
sudo systemctl is-active rk1-media-provision.service
|
|||
|
|
sudo systemctl is-active kodi-rk.service
|
|||
|
|
sudo journalctl -u rk1-media-provision.service -u kodi-rk.service -b --no-pager
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
All three should be active/successful and Kodi should be visible. The first
|
|||
|
|
boot may remain on a console while packages install.
|
|||
|
|
|
|||
|
|
## 2. One-command hardware qualification
|
|||
|
|
|
|||
|
|
```bash
|
|||
|
|
sudo rk1-media-selftest
|
|||
|
|
sudo rk1-media-selftest --strict --json | tee /tmp/rk1-selftest.json
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
The normal run performs short Vulkan, hardware encode, and NPU workloads when
|
|||
|
|
applicable. Strict mode treats a missing/disconnected advertised device as a
|
|||
|
|
failure. Confirm Panthor, an HDMI connector with EDID/modes, RKMPP decoder and
|
|||
|
|
encoder bindings, RGA2/RGA3, RKNPU, HDMI ALSA, Ethernet, eMMC, and NVMe.
|
|||
|
|
|
|||
|
|
Run the NPU directly across all three cores:
|
|||
|
|
|
|||
|
|
```bash
|
|||
|
|
rknn-inference-test --core all --iterations 10
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
## 3. 4K media acceptance
|
|||
|
|
|
|||
|
|
Use media you legally possess, with filenames containing `h264`, `hevc`,
|
|||
|
|
`vp9`, and `av1` so the self-test can select them:
|
|||
|
|
|
|||
|
|
```bash
|
|||
|
|
sudo rk1-media-selftest --media-dir /path/to/test-clips
|
|||
|
|
ffmpeg-rk -hide_banner -decoders | grep rkmpp
|
|||
|
|
ffmpeg-rk -hide_banner -encoders | grep rkmpp
|
|||
|
|
ffmpeg-rk -hide_banner -filters | grep rkrga
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
In Kodi, test at least 20 minutes each of 4K60 SDR H.264/HEVC, VP9, and AV1,
|
|||
|
|
plus seeking, pause/resume, subtitles, and HDMI PCM audio. Watch CPU usage and
|
|||
|
|
temperature; hardware-decoded playback should not pin all CPU cores. Also test
|
|||
|
|
CEC with `cec-client -l` and the intended remote/IR receiver.
|
|||
|
|
|
|||
|
|
HDR, lossless audio passthrough, HDCP/streaming-service DRM, and unusual
|
|||
|
|
10/12-bit chroma formats are separate acceptance items; this build does not
|
|||
|
|
claim them merely because 4K60 SDR succeeds.
|
|||
|
|
|
|||
|
|
## 4. Blank-HDMI decision tree
|
|||
|
|
|
|||
|
|
From SSH:
|
|||
|
|
|
|||
|
|
```bash
|
|||
|
|
for connector in /sys/class/drm/card*-HDMI-A-*; do
|
|||
|
|
printf '%s: ' "$connector"
|
|||
|
|
cat "$connector/status"
|
|||
|
|
cat "$connector/modes"
|
|||
|
|
done
|
|||
|
|
sudo journalctl -b -k | grep -Ei 'drm|hdmi|edid|vop|hdptx|panthor'
|
|||
|
|
sudo journalctl -b -u kodi-rk.service --no-pager
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
- No HDMI connector: DTB/kernel probe issue; collect diagnostics.
|
|||
|
|
- Connector says `disconnected`: focus on carrier HPD/DDC, cable, TV input, and
|
|||
|
|
the early-RK1 hardware note below—not Kodi.
|
|||
|
|
- `connected` but no modes: EDID/DDC or sink/cable issue.
|
|||
|
|
- Modes exist but Kodi loops: inspect DRM permissions/master and Kodi logs at
|
|||
|
|
`/var/lib/kodi/.kodi/temp/kodi.log`.
|
|||
|
|
- Kodi runs but the screen is black: stop Kodi and test direct KMS/Vulkan, then
|
|||
|
|
collect a bundle.
|
|||
|
|
|
|||
|
|
```bash
|
|||
|
|
sudo systemctl stop kodi-rk.service
|
|||
|
|
sudo kmscube
|
|||
|
|
sudo systemctl start kodi-rk.service
|
|||
|
|
sudo rk1-media-diagnostics
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
The diagnostic command writes locally and does not upload anything.
|
|||
|
|
|
|||
|
|
## Carrier/module caveat
|
|||
|
|
|
|||
|
|
The supplied Amazon ASIN is marketed as a KLAYERS Jetson **Orin** Nano/NX HDMI
|
|||
|
|
base board, rather than NVIDIA’s older Jetson Nano carrier. Its advertised
|
|||
|
|
layout matches the relevant Jetson-compatible RK1 HDMI lane/control pins, but a
|
|||
|
|
public KLAYERS schematic was not available, so physical validation is still
|
|||
|
|
required.
|
|||
|
|
|
|||
|
|
Turing documents that modules from its initial pool of 100 RK1s can fail HDMI
|
|||
|
|
with some Jetson-compatible carriers and may need two solder bridges. Do not
|
|||
|
|
guess the bridge locations: verify the module batch and obtain Turing’s exact
|
|||
|
|
hardware guidance before modifying it:
