Hello,
We bought recently 20 pcs of Carambola2 for our test project.
Carambola modules are installed on our board that provides all voltages and control signals.
The problem is that 4 out of 20 boards stopped on U-boot stage with the following message:
U-Boot 1.1.4-g33f82657-dirty (Sep 16 2013 - 16:09:28)
=====================================
CARAMBOLA2 v1.0 (AR9331) U-boot

DRAM: 4 MB
and nothing after that. I checked voltage (it is 3.3V), and state of Reset signal - all seems OK.
The rest of boards work well. Is it possible that we got faulty Carambola2 boards, or we should consider others possibilities?
Carambola modules have been soldered to our board with standard lead-free reflow profile.
