Back to Olinuxino and then... can't boot

[Akarix]

When i try to start my Olinuxino A20 Lime2 4Gb, the power led stay red, and the other is green and blinking.
Also, i seen some "white wax" on the back of the motherboard, near to the USB and Ethernet Port which is strange cause i didn't use it for a looong time.
I bought the SD card from Olimex with debian on it, and the battery model SY0605E.
So if anyone has and idea, i'm all hearing
Thanks

Have a look at the serial console at bootup, maybe the output helps.
