Overview -------- The P1023 process includes a performance optimized implementation of the QorIQ data Path Acceleration Architecture (DPAA). This architecture provides the infrastructure to support simplified sharing of networking interfaces and accelerators by multiple CPU cores. P1023 is an e500 based dual core SOC. P1023RDS board is a Low End Dual core platform supporting the P1023 processor of QorIQ series. Building U-boot --------------- To build the u-boot for P1023RDS: Configure to NOR boot: make P1023RDS_config Configure to NAND boot: make P1023RDS_NAND_config Build: make Board Switches -------------- Most switches on the board should not be changed. The most frequent user-settable switches on the board are used to configure the flash banks. J4: all open Default NOR flash boot switch setting: Sw3[1:8]: off on on off on on off off Sw4[1:8]: off off off on off off off off Sw6[1:8]: off on off on off on on off Sw7[1:8]: off on off off on off off off Sw8[1:8]: on off off off off off off off For NAND flash boot,set Sw4[1:4]: off on on on The default native ethernet setting is for RGMII mode. To use SGMII mode, set SW8[1:2]: OFF OFF SW7[6:7]: ON ON Memory Map ---------- 0x0000_0000 0x7fff_ffff DDR 2G Cacheable 0x8000_0000 0xbfff_ffff PCI Express Mem 1G non-cacheable 0xc000_0000 0xdfff_ffff PCI 512M non-cacheable 0xe100_0000 0xe3ff_ffff PCI IO range 4M non-cacheable 0xe000_0000 0xe003_ffff BCSR 256K BCSR 0xee00_0000 0xefff_ffff NOR flash 32M NOR flash 0xff00_0000 0xff3f_ffff DPAA_QBMAN 4M 0xff60_0000 0xff7f_ffff CCSR 2M non-cacheable 0xffa0_0000 0xffaf_ffff NAND FLASH 1M non-cacheable 0xffd0_0000 0xffd0_3fff L1 for stack 16K Cacheable TLB0 Flashing u-boot Images --------------- To program the image in the boot flash bank: NOR flash boot: => tftp 1000000 u-boot.bin => protect off all => erase eff80000 efffffff => cp.b 1000000 eff80000 80000 NAND flash boot: => tftp 1000000 u-boot-nand.bin => nand erase 0 80000 => nand write 1000000 0 80000 Firmware ucode location --------------------------------- Microcode(ucode) to FMAN's IRAM is needed to make FMAN Ethernet work. u-boot loads ucode FLASH. The location for ucode: NOR Flash: 0xfe000000 NAND Flash: 0x1f00000 Using the Device Tree Source File --------------------------------- To create the DTB (Device Tree Binary) image file, use a command similar to this: dtc -b 0 -f -I dts -O dtb p1023rds.dts > p1023rds.dtb Likely, that .dts file will come from here; linux-2.6/arch/powerpc/boot/dts/p1023rds.dts or make p1023rds.dtb ARCH=powerpc in linux-2.6 directory. Booting Linux ------------- Place a linux uImage in the TFTP disk area. tftp 1000000 uImage tftp 2000000 rootfs.ext2.gz.uboot tftp c00000 p1023rds.dtb bootm 1000000 2000000 c00000
