Overview
|
|
|
|
|
=========
|
|
|
|
|
The P2041 Processor combines four Power Architecture processor cores
|
|
|
|
|
with high-performance datapath acceleration architecture(DPAA), CoreNet
|
|
|
|
|
fabric infrastructure, as well as network and peripheral bus interfaces
|
|
|
|
|
required for networking, telecom/datacom, wireless infrastructure, and
|
|
|
|
|
military/aerospace applications.
|
|
|
|
|
|
|
|
|
|
P2041RDB board is a quad core platform supporting the P2041 processor
|
|
|
|
|
of QorIQ DPAA series.

CPLD command
|
|
|
|
|
============
|
|
|
|
|
The CPLD is used to control the power sequence and some serdes lane
|
|
|
|
|
mux function.
|
|
|
|
|
|
|
|
|
|
cpld reset - hard reset to default bank
|
|
|
|
|
cpld reset altbank - reset to alternate bank
|
|
|
|
|
cpld lane_mux <lane> <mux_value> - set multiplexed lane pin
|
|
|
|
|
lane 6: 0 -> slot1 (Default)
|
|
|
|
|
1 -> SGMII
|
|
|
|
|
lane a: 0 -> slot2 (Default)
|
|
|
|
|
1 -> AURORA
|
|
|
|
|
lane c: 0 -> slot2 (Default)
|
|
|
|
|
1 -> SATA0
|
|
|
|
|
lane d: 0 -> slot2 (Default)
|
|
|
|
|
1 -> SATA1
|
|
|
|
|
|
|
|
|
|
Using the Device Tree Source File
|
|
|
|
|
=================================
|
|
|
|
|
To create the DTB (Device Tree Binary) image file, use a command
|
|
|
|
|
similar to this:
|
|
|
|
|
dtc -O dtb -b 0 -p 1024 p2041rdb.dts > p2041rdb.dtb
|
|
|
|
|
|
|
|
|
|
Or use the following command:
|
|
|
|
|
{linux-2.6}/make p2041rdb.dtb ARCH=powerpc
|
|
|
|
|
|
|
|
|
|
then the dtb file will be generated under the following directory:
|
|
|
|
|
{linux-2.6}/arch/powerpc/boot/p2041rdb.dtb
|
|
|
|
|
|
|
|
|
|
Booting Linux
|
|
|
|
|
=============
|
|
|
|
|
Place a linux uImage in the TFTP disk area.
|
|
|
|
|
tftp 1000000 uImage
|
|
|
|
|
tftp 2000000 rootfs.ext2.gz.uboot
|
|
|
|
|
tftp 3000000 p2041rdb.dtb
|
|
|
|
|
bootm 1000000 2000000 3000000
|
