I have a 16GB RAM Raspberry Pi 3 I'm using a Mac 10.11.5 I have 2 SD cards: 64 GB micro SanDesk and 8GB micro SanDisk (both should be supported by the Pi)
I've formatted the SD card using the SD Association's Formatting Tool. When formatting, I selected "Overwrite Format" and I set "Logical Address Adjustment" to "Yes". After formatting using SDFormatter, I then use the Mac Disk Utility and did an Erase operation making sure to select MS-DOS (FAT) from the Format drop down. I then copied NOOBS version 1.9.2 onto the SD card and inserted into my Pi. I plugged the Pi into power (using an Android charger plugged into a wall socket).
What happens is that the red light turns on and remains steady and then the green light blinks JUST ONCE and then never blinks again. Nothing appears on screen. I've tried all this without plugging in any HDMI cable into the Pi and the same thing happens. I've tried two different SD cards and the same thing happens.
Does this mean my Pi is defective?
