No Signal - New Build Rasbperry Pi 4
By Alfredo Granados @granadosjr
- @david
Let me start by saying that I've run through most of the previous forum entries on the No Signal issue. I've created a shareable link of logs. https://logs.tinypilotkvm.com/2E7NjSo3
I'm also attaching build details. This is the TinyPilot Hobbyist version. I have it attached via an adapter from micro hdmi to hdmi. the other end I had a dual boot linux/windows dell laptop and hp laptop. i've also swapped cables and tried a micro hdmi to hdmi cable with no improvement.
raspberry pi 4, 8gb.

In reply togranadosjr⬆:David @david2023-09-04 11:10:06.669ZHi @granadosjr, sorry you're running into this No Signal issue on your Hobbyist TinyPilot.
And thanks for sharing all those details & logs.
Your logs suggest there's an issue accessing your capture device:
Can't access device: No such file or directoryCan you tell me what capture device you're using? Is it the HDMI-to-USB device we suggest in our Build a KVM guide?
- GAlfredo Granados @granadosjr
Hello, It sounds as if I'm missing a component. Is there somewhere where it list the required parts? I am not running it with a capture card. I have only tried with a converter from micro hdmi to hdmi and I've also tried with a micro hdmi cable to hdmi.
what is the make and model of the required capture device?
David @david2023-09-05 14:10:50.461ZIt sounds like you've been trying to use your Raspberry Pi's onboard micro HDMI. Unfortunately, the Raspberry Pi's onboard micro HDMI port is only for video output - it can't receive a video signal, which is why you need a separate capture device.
In our "How to build your own TinyPilot" guide there's a parts list that outlines the required parts. In this case, you'll need an HDMI to USB capture dongle.
It sounds like you have all of the other parts you require. Once you've installed the capture device, you may also need to re-flash your microSD card with the Hobbyist version of TinyPilot Pro, rather than the Voyager version.
Hope that helps!
