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.
Boot from NOR flash
===================
1. Build image
make P2041RDB_config
make all
2. Program image
=> tftp 1000000 u-boot.bin
=> protect off all
=> erase eff40000 efffffff
=> cp.b 1000000 eff40000 c0000
3. Program RCW
=> tftp 1000000 rcw.bin
=> protect off all
=> erase e8000000 e801ffff
=> cp.b 1000000 e8000000 50
4. Program FMAN Firmware ucode
=> tftp 1000000 ucode.bin
=> protect off all
=> erase eff00000 eff3ffff
=> cp.b 1000000 eff00000 2000
5. Change DIP-switch
SW1[1-5] = 10110
Note: 1 stands for 'on', 0 stands for 'off'
Boot from SDCard
===================
1. Build image
make P2041RDB_SDCARD_config
make all
2. Generate PBL imge
Use PE tool to produce a image used to be programed to
SDCard which contains RCW and U-Boot image.
3. Program the PBL image to SDCard
=> tftp 1000000 pbl_sd.bin
=> mmcinfo
=> mmc write 1000000 8 672
4. Program FMAN Firmware ucode
=> tftp 1000000 ucode.bin
=> mmc write 1000000 690 10
5. Change DIP-switch
SW1[1-5] = 01100
Note: 1 stands for 'on', 0 stands for 'off'
Boot from SPI flash
===================
1. Build image
make P2041RDB_SPIFLASH_config
make all
2. Generate PBL imge
Use PE tool to produce a image used to be programed to
SPI flash which contains RCW and U-Boot image.
3. Program the PBL image to SPI flash
=> tftp 1000000 pbl_spi.bin
=> spi probe 0
=> sf erase 0 100000
=> sf write 1000000 0 $filesize
4. Program FMAN Firmware ucode
=> tftp 1000000 ucode.bin
=> sf erase 110000 10000
=> sf write 1000000 110000 $filesize
5. Change DIP-switch
SW1[1-5] = 10100
Note: 1 stands for 'on', 0 stands for 'off'
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
