Hi, 
I received confirmation from FriendlyArm by email that both M2a and M3 has been discontinued.
Apparently they can continue producing with a relatively hight MOQ.

Sadly no reponses from them about the lifespan of their products.

it would be nice if they posed expected date of product line termination... but still does not change the fact that I can't get anything to run on it... stuff that igor posted does not work... it just dies... with what ever i posted before...

What do you mean by 7505 ? Do you mean 7805 Voltage Regulator ? Be aware that those are 1A only ...

You don't any 5VDC Wall plugged PSU with a barrel connector ?

 

EDIT : When I'm running of 5V PSU, I take some 12V and use those DC-DC converters : http://www.ebay.ca/itm/5pcs-Mini-360-DC-DC-Buck-Converter-Step-Down-Module-4-75V-23V-to-1V-17V-EV-/272877133247

Running out of ideas since I can't replicate this problem. It still could be a failed / badly written (bad) SD card. This cheap buck converter is also not good enough to rule out underpowering. Have you tried booting without having anything attached to USB?


Add: I did few tests limiting the current and I could not boot the board when input current was below ~1.5A without having anything except HDMI. Perhaps there (HDMI) is a problem? Further. Stressing the board pulls ~1.6A and it was pretty easy to crash the board when PSU was limited to 1.8A ... which is close to Chinese "3A" :)
