| 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 eff40000 efffffff |
| => cp.b 1000000 eff40000 c0000 |
| |
| 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 |
