Overview
|
|
=========
|
|
The P1010RDB-PB is a Freescale Reference Design Board that hosts the P1010 SoC.
|
|
P1010RDB-PB is a variation of previous P1010RDB-PA board.
|
|
|
|
The P1010 is a cost-effective, low-power, highly integrated host processor
|
|
based on a Power Architecture e500v2 core (maximum core frequency 1GHz),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.
|
|
|
|

|
|
|
|
Board connectors:
|
|
- Mini-ITX power supply connector
|
|

|
|
Switch P1010RDB-PB boot mode via software without setting DIP-switch
|
|
====================================================================
|
|
=> run boot_bank0 (boot from NOR bank0)
|
|
=> run boot_bank1 (boot from NOR bank1)
|
|
=> run boot_nand (boot from NAND flash)
|
|
=> run boot_spi (boot from SPI flash)
|
|
=> run boot_sd (boot from SD card)

Setting of pin mux
|
|
==================
|
|
Since pins multiplexing, TDM and CAN are muxed with SPI flash.
|
|
SDHC is muxed with IFC. IFC and SPI flash are enabled by default.
|
|
|
|
To enable TDM:
|
|
=> setenv hwconfig fsl_p1010mux:tdm_can=tdm
|
|
=> save;reset
|
|
|
|
To enable FlexCAN:
|
|
=> setenv hwconfig fsl_p1010mux:tdm_can=can
|
|
=> save;reset
|
|
|
|
To enable SDHC in case of NOR/NAND/SPI boot
|
|
a) For temporary use case in runtime without reboot system
|
|
run 'mux sdhc' in U-Boot to validate SDHC with invalidating IFC.
|
|
|
|
b) For long-term use case
|
|
set 'esdhc' in hwconfig and save it.
|
|
|
|
To enable IFC in case of SD boot
|
|
a) For temporary use case in runtime without reboot system
|
|
run 'mux ifc' in U-Boot to validate IFC with invalidating SDHC.
|
|
|
|
b) For long-term use case
|
|
set 'ifc' in hwconfig and save it.
|

Build images for different boot mode
|
|
====================================
|
|
First setup cross compile environment on build host
|
|
$ export CROSS_COMPILE=<your-compiler-path>/powerpc-linux-gnu-
|
|
|
|
1. For NOR boot
|
|
$ make P1010RDB-PB_NOR
|
|
|
|
2. For NAND boot
|
|
$ make P1010RDB-PB_NAND
|
|
|
|
3. For SPI boot
|
|
$ make P1010RDB-PB_SPIFLASH
|
|
|
|
4. For SD boot
|
|
$ make P1010RDB-PB_SDCARD
|
|
|
|
|
|
Steps to program images to flash for different boot mode
|
|
========================================================
|
|
1. NOR boot
|
|
=> tftp 1000000 u-boot.bin
|
|
For bank0
|
|

|
|
set SW1[8]=0, SW4[1:4]= 1111 and SW3[3:4]= 00, then power on the board
|
|
|
|
For bank1
|
|
=> pro off all;era eef40000 eeffffff;cp.b 1000000 eef40000 $filesize
|
|
set SW1[8]=1, SW4[1:4]= 1111 and SW3[3:4]= 00, then power on the board
|
|
|
|
2. NAND boot
|
|
=> tftp 1000000 u-boot-nand.bin
|
|
=> nand erase 0 $filesize; nand write $loadaddr 0 $filesize
|
|
Set SW4[1:4]= 1010 and SW3[3:4]= 01, then power on the board
|
|
|
|
3. SPI boot
|
|
1) cat p1010rdb-config-header.bin u-boot.bin > u-boot-spi-combined.bin
|
|
2) => tftp 1000000 u-boot-spi-combined.bin
|
|
3) => sf probe 0; sf erase 0 100000; sf write 1000000 0 100000
|
|
set SW4[1:4]= 0110 and SW3[3:4]= 00, then power on the board
|
|
|
|
4. SD boot
|
|
1) cat p1010rdb-config-header.bin u-boot.bin > u-boot-sd-combined.bin
|
|
2) => tftp 1000000 u-boot-sd-combined.bin
|
|
3) => mux sdhc
|
|
4) => mmc write 1000000 0 1050
|
|
set SW4[1:4]= 0111 and SW3[3:4]= 10, then power on the board
|
|
|
|
|
|
Boot Linux from network using TFTP on P1010RDB-PB
|
|
=================================================
|
|
Place uImage, p1010rdb.dtb and rootfs files in the TFTP download path.
|
|
=> tftp 1000000 uImage
|
|
=> tftp 2000000 p1010rdb.dtb
|
|
=> tftp 3000000 rootfs.ext2.gz.uboot.p1010rdb
|
|
=> bootm 1000000 3000000 2000000
