| 2 | -------- |
| 3 | The P1023 process includes a performance optimized implementation of the |
| 4 | QorIQ data Path Acceleration Architecture (DPAA). This architecture |
| 5 | provides the infrastructure to support simplified sharing of networking |
| 6 | interfaces and accelerators by multiple CPU cores. P1023 is an e500 based |
| 7 | dual core SOC. |
| 8 | |
| 9 | P1023RDS board is a Low End Dual core platform supporting the P1023 |
| 10 | processor of QorIQ series. |
| 11 | |
| 12 | Building U-boot |
| 13 | --------------- |
| 14 | To build the u-boot for P1023RDS: |
| 15 | Configure to NOR boot: |
| 16 | make P1023RDS_config |
| 17 | Configure to NAND boot: |
| 18 | make P1023RDS_NAND_config |
| 19 | Build: |
| 20 | make |
| 21 | |
| 22 | Board Switches |
| 23 | -------------- |
| 24 | Most switches on the board should not be changed. The most frequent |
| 25 | user-settable switches on the board are used to configure |
| 26 | the flash banks. |
| 27 | |
| 28 | J4: all open |
| 29 | |
| 30 | Default NOR flash boot switch setting: |
| 31 | Sw3[1:8]: off on on off on on off off |
| 32 | Sw4[1:8]: off off off on off off off off |
| 33 | Sw6[1:8]: off on off on off on on off |
| 34 | Sw7[1:8]: off on off off on off off off |
| 35 | Sw8[1:8]: on off off off off off off off |
| 36 | |
| 37 | For NAND flash boot,set |
| 38 | Sw4[1:4]: off on on on |
| 39 | |
| 40 | The default native ethernet setting is for RGMII mode. |
| 41 | To use SGMII mode, set |
| 42 | SW8[1:2]: OFF OFF |
| 43 | SW7[6:7]: ON ON |
| 44 | |
| 45 | Memory Map |
| 46 | ---------- |
| 47 | 0x0000_0000 0x7fff_ffff DDR 2G Cacheable |
| 48 | 0x8000_0000 0xbfff_ffff PCI Express Mem 1G non-cacheable |
| 49 | 0xc000_0000 0xdfff_ffff PCI 512M non-cacheable |
| 50 | 0xe100_0000 0xe3ff_ffff PCI IO range 4M non-cacheable |
| 51 | |
| 52 | 0xe000_0000 0xe003_ffff BCSR 256K BCSR |
| 53 | 0xee00_0000 0xefff_ffff NOR flash 32M NOR flash |
| 54 | 0xff00_0000 0xff3f_ffff DPAA_QBMAN 4M |
| 55 | 0xff60_0000 0xff7f_ffff CCSR 2M non-cacheable |
| 56 | 0xffa0_0000 0xffaf_ffff NAND FLASH 1M non-cacheable |
| 57 | 0xffd0_0000 0xffd0_3fff L1 for stack 16K Cacheable TLB0 |
| 58 | |
| 59 | Flashing u-boot Images |
| 60 | --------------- |
| 61 | To program the image in the boot flash bank: |
| 62 | NOR flash boot: |
| 63 | => tftp 1000000 u-boot.bin |
| 64 | => protect off all |
| 65 | => erase eff80000 efffffff |
| 66 | => cp.b 1000000 eff80000 80000 |
| 67 | |
| 68 | NAND flash boot: |
| 69 | => tftp 1000000 u-boot-nand.bin |
| 70 | => nand erase 0 80000 |
| 71 | => nand write 1000000 0 80000 |
| 72 | |
| 73 | Firmware ucode location |
| 74 | --------------------------------- |
| 75 | Microcode(ucode) to FMAN's IRAM is needed to make FMAN Ethernet work. |
| 76 | u-boot loads ucode FLASH. The location for ucode: |
| 77 | NOR Flash: 0xfe000000 |
| 78 | NAND Flash: 0x1f00000 |
| 79 | |
| 80 | Using the Device Tree Source File |
| 81 | --------------------------------- |
| 82 | To create the DTB (Device Tree Binary) image file, |
| 83 | use a command similar to this: |
| 84 | |
| 85 | dtc -b 0 -f -I dts -O dtb p1023rds.dts > p1023rds.dtb |
| 86 | |
| 87 | Likely, that .dts file will come from here; |
| 88 | |
| 89 | linux-2.6/arch/powerpc/boot/dts/p1023rds.dts |
| 90 | or |
| 91 | make p1023rds.dtb ARCH=powerpc |
| 92 | in linux-2.6 directory. |
| 93 | |
| 94 | Booting Linux |
| 95 | ------------- |
| 96 | Place a linux uImage in the TFTP disk area. |
| 97 | |
| 98 | tftp 1000000 uImage |
| 99 | tftp 2000000 rootfs.ext2.gz.uboot |
| 100 | tftp c00000 p1023rds.dtb |
| 101 | bootm 1000000 2000000 c00000 |
