Sorry for the lack of details, I was indeed not very precise. From what I 
remember, the system did not boot when no SD card (with a Linux OS on it) 
was inserted, and I think only 3 out of the 4 LEDs were lit. But I'm not 
sure about that. 
I'm getting a serial adapter, and also more SD cards (I only have one right 
now, and it's really long to reformat it each time I want to do something), 
and I'll get back to you with more info after retrying more rigorously!

Also, I have a strange problem where I have a REALLY hard time accessing 
SSH while running a Linux from the SD card: I can see the virtual network 
adapter in Windows, but most of the time it shows "cable not connected" and 
I need to reboot many times (pushing the button and waiting 1 minute for 
shutdown, and then reboot with the Boot button pushed) before I can finally 
have access to the connection). Sometimes, when the card is freshly 
formatted, the connection works at first boot, but as soon as I reboot it 
is gone... So yeah, getting a serial adapter will most definitely help. 
(I'm running Win7 64 bits and I have no problem whatsoever with the 
connection when the Linux is ran from the eMMC).

Thank you RobertCNelson!

Regards,

Alexandre
