I recently purchased a Raspberry Pi 2B+, and I am trying to run the RetroPie (backed by raspbian) operating system on it. The first time I plug in the pi, it boots normally into the operating system (normal PWR and ACT activity). Without making any changes, when the pi is shut down it no longer boots up. Reformatting the SD card lets the pi boot once, but then not a second time.
When the pi is booting up the second time, the green ACT light acts as normal for about 30 seconds, then pulses once a second for a few minutes before turning off for good. The PWR light stays lit the entire process.
I have tried the process with two different SD cards,
- Sandisk 8GB Class 4 microSD
- Samsung 32GB Class 10 microSD.
Does anyone have any suggestions? I don't know if this is relevant, but when it boots there is a USB keyboard and mouse, USB wifi adapter, and monitor with an HDMI to VGA converter plugged in.
Thanks in advance.
EDIT: Running the reboot command through the terminal boots normally. Also, NOOBS will boot twice, just not retropie.
