| 2 | ========= |
| 3 | The P2041 Processor combines four Power Architecture processor cores |
| 4 | with high-performance datapath acceleration architecture(DPAA), CoreNet |
| 5 | fabric infrastructure, as well as network and peripheral bus interfaces |
| 6 | required for networking, telecom/datacom, wireless infrastructure, and |
| 7 | military/aerospace applications. |
| 8 | |
| 9 | P2041RDB board is a quad core platform supporting the P2041 processor |
| 10 | of QorIQ DPAA series. |

| 64 | =================== |
| 65 | 1. Build image |
| 66 | make P2041RDB_SPIFLASH_config |
| 67 | make all |
| 68 | |
| 69 | 2. Generate PBL imge |
| 70 | Use PE tool to produce a image used to be programed to |
| 71 | SPI flash which contains RCW and U-Boot image. |
| 72 | |
| 73 | 3. Program the PBL image to SPI flash |
| 74 | => tftp 1000000 pbl_spi.bin |
| 75 | => spi probe 0 |
| 76 | => sf erase 0 100000 |

| 87 | |
| 88 | CPLD command |
| 89 | ============ |
| 90 | The CPLD is used to control the power sequence and some serdes lane |
| 91 | mux function. |
| 92 | |
| 93 | cpld reset - hard reset to default bank |
| 94 | cpld reset altbank - reset to alternate bank |
| 95 | cpld lane_mux <lane> <mux_value> - set multiplexed lane pin |
| 96 | lane 6: 0 -> slot1 (Default) |
| 97 | 1 -> SGMII |
| 98 | lane a: 0 -> slot2 (Default) |
| 99 | 1 -> AURORA |
| 100 | lane c: 0 -> slot2 (Default) |
| 101 | 1 -> SATA0 |
| 102 | lane d: 0 -> slot2 (Default) |
| 103 | 1 -> SATA1 |
| 104 | |
| 105 | Using the Device Tree Source File |
| 106 | ================================= |
| 107 | To create the DTB (Device Tree Binary) image file, use a command |
| 108 | similar to this: |
| 109 | dtc -O dtb -b 0 -p 1024 p2041rdb.dts > p2041rdb.dtb |
| 110 | |
| 111 | Or use the following command: |
| 112 | {linux-2.6}/make p2041rdb.dtb ARCH=powerpc |
| 113 | |
| 114 | then the dtb file will be generated under the following directory: |
| 115 | {linux-2.6}/arch/powerpc/boot/p2041rdb.dtb |
| 116 | |
| 117 | Booting Linux |
| 118 | ============= |
| 119 | Place a linux uImage in the TFTP disk area. |
| 120 | tftp 1000000 uImage |
| 121 | tftp 2000000 rootfs.ext2.gz.uboot |
| 122 | tftp 3000000 p2041rdb.dtb |
| 123 | bootm 1000000 2000000 3000000 |
