|
=========
|
|
The P1010RDB is a Freescale reference design board that hosts the P1010 SoC.
|
|
|
|
The P1010 is a cost-effective, low-power, highly integrated host processor
|
|
based on a Power Architecture e500v2 core (maximum core frequency 800/1000 MHz),
|
|
that addresses the requirements of several routing, gateways, storage, consumer,
|
|
and industrial applications. Applications of interest include the main CPUs and
|
|
I/O processors in network attached storage (NAS), the voice over IP (VoIP)
|
|
router/gateway, and wireless LAN (WLAN) and industrial controllers.

Serial Port Configuration on P1010RDB
|
|
=====================================
|
|
Configure the serial port of the attached computer with the following values:
|
|
-Data rate: 115200 bps
|
|
-Number of data bits: 8
|
|
-Parity: None
|
|
-Number of Stop bits: 1
|
|
-Flow Control: Hardware/None
|
|
|
|
|
|
Settings of DIP-switch
|
|
======================
|
|
SW4[1:4]= 1111 and SW6[4]=0 for boot from 16bit NOR flash
|
|
SW4[1:4]= 1000 and SW6[4]=1 for boot from 8bit NAND flash
|
|
SW4[1:4]= 0110 and SW6[4]=0 for boot from SPI flash
|
|
Note: 1 stands for 'on', 0 stands for 'off'
|
|
|
|
|
|
Setting of hwconfig
|
|
===================
|
|
If FlexCAN or TDM is needed, please set "fsl_p1010mux:tdm_can=can" or
|
|
"fsl_p1010mux:tdm_can=tdm" explicitly in u-booot prompt as below for example:
|
|
setenv hwconfig "fsl_p1010mux:tdm_can=tdm;usb1:dr_mode=host,phy_type=utmi"
|
|
By default, don't set fsl_p1010mux:tdm_can, in this case, spi chip selection
|
|
is set to spi-flash instead of to SLIC/TDM/DAC and tdm_can_sel is set to TDM
|
|
instead of to CAN/UART1.
|
|
|
|
|
|
Build and burn u-boot to NOR flash
|
|
==================================
|
|
1. Build u-boot.bin image
|
|
export ARCH=powerpc
|
|
export CROSS_COMPILE=/your_path/powerpc-linux-gnu-
|
|
make P1010RDB_NOR
|
|
|
|
2. Burn u-boot.bin into NOR flash
|
|
=> tftp $loadaddr $uboot
|
|
=> protect off eff80000 +$filesize
|
|
=> erase eff80000 +$filesize
|
|
=> cp.b $loadaddr eff80000 $filesize
|
|
|
|
3. Check SW4[1:4]= 1111 and SW6[4]=0, then power on.
|
|
|
|
|
|
Alternate NOR bank
|
|
============================
|
|
1. Burn u-boot.bin into alternate NOR bank
|
|
=> tftp $loadaddr $uboot
|
|
=> protect off eef80000 +$filesize
|
|
=> erase eef80000 +$filesize
|
|
=> cp.b $loadaddr eef80000 $filesize
|
|
|
|
2. Switch to alternate NOR bank
|
|
=> mw.b ffb00009 1
|
|
=> reset
|
|
or set SW1[8]= ON
|
|
|
|
SW1[8]= OFF: Upper bank used for booting start
|
|
SW1[8]= ON: Lower bank used for booting start
|
|
CPLD NOR bank selection register address 0xFFB00009 Bit[0]:
|
|
0 - boot from upper 4 sectors
|
|
1 - boot from lower 4 sectors
|
|
|
|
|
|
Build and burn u-boot to NAND flash
|
|
===================================
|
|
1. Build u-boot.bin image
|
|
export ARCH=powerpc
|
|
export CROSS_COMPILE=/your_path/powerpc-linux-gnu-
|
|
make P1010RDB_NAND
|
|
|
|
2. Burn u-boot-nand.bin into NAND flash
|
|
=> tftp $loadaddr $uboot-nand
|
|
=> nand erase 0 $filesize
|
|
=> nand write $loadaddr 0 $filesize
|
|
|
|
3. Check SW4[1:4]= 1000 and SW6[4]=1, then power on.
|
|
|
|
|
|
|
|
Build and burn u-boot to SPI flash
|
|
==================================
|
|
1. Build u-boot-spi.bin image
|
|
make P1010RDB_SPIFLASH_config; make
|
|
Boot up kernel with rootfs.ext2.gz.uboot.p1010rdb
|
|
Download u-boot.bin to linux and you can find some config files
|
|
under /usr/share such as config_xx.dat. Do below command:
|
|
boot_format config_ddr3_1gb_p1010rdb_800M.dat u-boot.bin -spi \
|
|
u-boot-spi.bin
|
|
to generate u-boot-spi.bin.
|
|
|
|
2. Burn u-boot-spi.bin into SPI flash
|
|
=> tftp $loadaddr $uboot-spi
|
|
=> sf erase 0 100000
|
|
=> sf write $loadaddr 0 $filesize
|
|
|
|
3. Check SW4[1:4]= 0110 and SW6[4]=0, then power on.
|
|
|
|
|
|
|
|
CPLD POR setting registers
|
|
==========================
|
|
1. Set POR switch selection register (addr 0xFFB00011) to 0.
|
|
2. Write CPLD POR registers (BCSR0~BCSR3, addr 0xFFB00014~0xFFB00017) with
|
|
proper values.
|
|
If change boot ROM location to NOR or NAND flash, need write the IFC_CS0
|
|
switch command by I2C.
|
|
3. Send reset command.
|
|
After reset, the new POR setting will be implemented.
|
|
|
|
Two examples are given in below:
|
|
Switch from NOR to NAND boot with default frequency:
|
|
=> i2c dev 0
|
|
=> i2c mw 18 1 f9
|
|
=> i2c mw 18 3 f0
|
|
=> mw.b ffb00011 0
|
|
=> mw.b ffb00017 1
|
|
=> reset
|
|
Switch from NAND to NOR boot with Core/CCB/DDR (800/400/667 MHz):
|
|
=> i2c dev 0
|
|
=> i2c mw 18 1 f1
|
|
=> i2c mw 18 3 f0
|
|
=> mw.b ffb00011 0
|
|
=> mw.b ffb00014 2
|
|
=> mw.b ffb00015 5
|
|
=> mw.b ffb00016 3
|
|
=> mw.b ffb00017 f
|
|
=> reset
|
|
|
|
|
|
|
|
Boot Linux from network using TFTP on P1010RDB
|
|
==============================================
|
|
Place uImage, p1010rdb.dtb and rootfs files in the TFTP disk area.
|
|
=> tftp 1000000 uImage
|
|
=> tftp 2000000 p1010rdb.dtb
|
|
=> tftp 3000000 rootfs.ext2.gz.uboot.p1010rdb
|
|
=> bootm 1000000 3000000 2000000
