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
