HA Yellow first install not working [resolved]

So, I bought a Yellow kit, followed the install instructions. Got to ‘Installing Software on Kit’ step 10. Got the ‘during boot’ blinky yellow, went to ‘solid on’ yellow, then … nothing. Just sits there forever. The router sees the ‘yellow-installer’ on the Ethernet port, so that’s not it. I’ve got solid yellow and red, and an about one-per-second blinky green. Advice?

Which troubleshooting steps have you done?

Not much. I’m not really sure where to start. The ‘troubleshoot’ link on Step 10 goes to a page for ‘yellow LED keeps blinking steady’, but that’s not what I have. The link you just posted just says ‘indicates a network issue’, but I don’t know what to check. I have internet access through the modem that HAYellow is plugged into, and the modem recognizes yellow-installer as being plugged into it.

I would try the following troubleshooting step:

So, just to close this out. I never did get past Step 10 using the standard install instructions.

The troubleshooting step provided above by Mark didn’t work (The Yellow showed up under ‘Other’ instead of ‘Ports’, thus there wasn’t a COM port that I could PuTTY to. My Mac didn’t recognize it at all.)

I needed to load the entire OS (download from the git repo, ‘rpiboot’ and ‘RPI Imager’ using the full OS instead of the initial installer mini). Then, things started working great.
