Still no success, so I looked a little closer at everything. My KVM is old enough that sometimes the kludge of USB to PS2 cables isn’t always recognized, requiring a reboot. The Zero booted and the monitor displayed the NOOB setup screen but neither the mouse nor the keyboard responded. Pi Zero connected to KVM with Pi 2 in corner I swapped out the WiFi dongle on the OTG for a USB to PS2 keyboard and mouse cable which in turn plugged into the KVM cable. I formatted the SD card, unzipped the NOOB file, and copied the resulting directory to the SD. That was the slowest download of a 1 Gb file I’ve ever seen but it did finally finish. Off I went to the Pi web site for the newest version of NOOB. I put the SD card back in the Zero and got eight flashes. The commands were the standard for updating a Linux system: sudo apt-get update Further searching suggested updating the SD card while running it on a GTZPi, which I did. The flashing LED meant the Zero couldn’t read the file system on the SD card. With power applied the activity LED lit… and then flashed eight times, went solid, flashed eight times, and repeated the pattern. I connected the USB On the Go (OTG) cable with a WiFi dongle and the mini-HDMI port to my keyboard-video-monitor (KVM) switch. One of the first hacks for a Zero just used an existing SD card from a GTZPi so I tried that. The speed difference between them was noticeable so I decided to dive in and further test the performance of the Zero.įirst Try Pi Zero with WiFi dongle on USB OTG My experience with the Pi family began with the Pi B+ and, shortly after that, the Pi 2. With no rush on delivery it eventually got here, and I finally got around to looking at it. There are a few Greater Than Zero Pis (GTZPi) already on my workbench so my purchase was driven by curiosity, not necessity. I ordered a Raspberry Pi Zero from Adafruit in their Startup Pack right after they were released.
