I use RPi B+ for playing a folder of videos automatically after boot. But the problem is that during the initial boot, the red LED on the board blinks 2 times (one after 4-5 seconds of boot, and the other after 5-6 seconds.)
I searched a lot on the net, and I'm pretty sure that the red LED on the board is related to power only.
First, I was using a cheap usb mobile charger; the red LED used to blink very often, both at boot, and later on operation time.
So I changed the PSU, and bought a reliable 5 V / 5 A power adapter!!
The number of the blinks of the red LED decreased. It was good. But still I would get blinks on the beginning of each video.
So I changed the power cables to thicker ones, because they can provide enough current.
Fortunately, the blinks on the beginning of each video disappeared, and it got solved.
However, still I get those 2 red LED blinks at the initial boot.
What would be the cause !!?
