| 6 | ----------------- |
| 7 | |
| 8 | (a) Ubuntu packages (CROSS_COMPILE=arm-linux-gnueabi-) |
| 9 | |
| 10 | If you are building U-Boot on Ubuntu, its standard package is recommended. |
| 11 | You can install it as follows: |
| 12 | |
| 13 | $ sudo apt-get install gcc-arm-linux-gnueabi- |
| 14 | |
| 15 | (b) Linaro compilers (CROSS_COMPILE=arm-linux-gnueabihf-) |
| 16 | |
| 17 | You can download pre-built toolchains from: |
| 18 | |
| 19 | http://www.linaro.org/downloads/ |
| 20 | |
| 21 | (c) kernel.org compilers (CROSS_COMPILE=arm-unknown-linux-gnueabi-) |
| 22 | |
| 23 | You can download pre-built toolchains from: |
| 24 | |
| 25 | ftp://www.kernel.org/pub/tools/crosstool/files/bin/ |

| 64 | to use your favorite compiler. |

| 67 | Burn U-Boot images to NAND |
| 68 | -------------------------- |
| 69 | |
| 70 | Write two files to the NAND device as follows: |
Masahiro Yamada | f4e190e | 2015-08-28 20:13:18 +0900 | [diff] [blame] | 71 | - spl/u-boot-spl-dtb.bin at the offset address 0x00000000 |
| 72 | - u-boot-dtb.img at the offset address 0x00010000 |
Masahiro Yamada | 7168da1 | 2015-02-05 14:30:23 +0900 | [diff] [blame] | 73 | |
| 74 | If a TFTP server is available, the images can be easily updated. |
Masahiro Yamada | f4e190e | 2015-08-28 20:13:18 +0900 | [diff] [blame] | 75 | Just copy the u-boot-spl-dtb.bin and u-boot-dtb.img to the TFTP public |
| 76 | directory, and then run the following command at the U-Boot command line: |
Masahiro Yamada | 7168da1 | 2015-02-05 14:30:23 +0900 | [diff] [blame] | 77 | |
| 78 | => run nandupdate |
| 79 | |
| 80 | |
| 81 | UniPhier specific commands |

| 83 | |
| 84 | - pinmon (enabled by CONFIG_CMD_PINMON) |
| 85 | shows the boot mode pins that has been latched at the power-on reset |
| 86 | |

| 106 | |
| 107 | The recommended bit switch settings are as follows: |
| 108 | |
| 109 | SW2 OFF(1)/ON(0) Description |
| 110 | ------------------------------------------ |
| 111 | bit 1 <---- BKSZ[0] |
| 112 | bit 2 ----> BKSZ[1] |
| 113 | bit 3 <---- SoC Bus Width 16/32 |
| 114 | bit 4 <---- SERIAL_SEL[0] |
| 115 | bit 5 ----> SERIAL_SEL[1] |
| 116 | bit 6 ----> BOOTSWAP_EN |
| 117 | bit 7 <---- CS1/CS5 |
| 118 | bit 8 <---- SOC_SERIAL_DISABLE |
| 119 | |
| 120 | SW8 OFF(1)/ON(0) Description |
| 121 | ------------------------------------------ |
| 122 | bit 1 ----> CS1_SPLIT |
| 123 | bit 2 <---- CASE9_ON |
| 124 | bit 3 <---- CASE10_ON |
| 125 | bit 4 Don't Care Reserve |
| 126 | bit 5 Don't Care Reserve |
| 127 | bit 6 Don't Care Reserve |
| 128 | bit 7 ----> BURST_EN |
| 129 | bit 8 ----> FLASHBUS32_16 |
| 130 | |
| 131 | The BKSZ[1:0] specifies the address range of memory slot and peripherals |
| 132 | as follows: |
| 133 | |
| 134 | BKSZ Description RAM slot Peripherals |

| 141 | Set BSKZ[1:0] to 0b01 for U-Boot. |
| 142 | This mode is the most handy because EA[24] is always supported by the save pin |
| 143 | mode of the system bus. On the other hand, EA[25] is not supported for some |
| 144 | newer SoCs. Even if it is, EA[25] is not connected on most of the boards. |
