[U-Boot] [PATCH 2/2] ARM: Add support for IGEP COM AQUILA/CYGNUS
Enric Balletbo i Serra
eballetbo at gmail.com
Wed Apr 3 15:12:03 CEST 2013
From: Enric Balletbo i Serra <eballetbo at iseebcn.com>
The IGEP COM AQUILA and CYGNUS are industrial processors modules with
following highlights:
o AM3352/AM3354 Texas Instruments processor
o Cortex-A8 ARM CPU
o 3.3 volts Inputs / Outputs use industrial
o 256 MB DDR3 SDRAM / 128 Megabytes FLASH
o MicroSD card reader on-board
o Ethernet controller on-board
o JTAG debug connector available
o Designed for industrial range purposes
