| 5 | Tested toolchains |
| 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/ |
| 26 | |
| 27 | |
| 28 | Compile the source |
| 29 | ------------------ |
| 30 | |
| 31 | PH1-Pro4: |
| 32 | $ make ph1_pro4_defconfig |
| 33 | $ make CROSS_COMPILE=arm-linux-gnueabi- |
| 34 | |
| 35 | PH1-LD4: |
| 36 | $ make ph1_ld4_defconfig |
| 37 | $ make CROSS_COMPILE=arm-linux-gnueabi- |
| 38 | |
| 39 | PH1-sLD8: |
| 40 | $ make ph1_sld8_defconfig |
| 41 | $ make CROSS_COMPILE=arm-linux-gnueabi- |
| 42 | |
| 43 | You may wish to change the "CROSS_COMPILE=arm-linux-gnueabi-" |
| 44 | to use your favorite compiler. |
| 45 | |
| 46 | |
| 47 | Burn U-Boot images to NAND |
| 48 | -------------------------- |
| 49 | |
| 50 | Write two files to the NAND device as follows: |
| 51 | - spl/u-boot-spl.bin at the offset address 0x00000000 |
| 52 | - u-boot-dtb.img at the offset address 0x00010000 |
| 53 | |
| 54 | If a TFTP server is available, the images can be easily updated. |
| 55 | Just copy the u-boot-spl.bin and u-boot-dtb.img to the TFTP public directory, |
| 56 | and then run the following command at the U-Boot command line: |
| 57 | |
| 58 | => run nandupdate |
| 59 | |
| 60 | |
| 61 | UniPhier specific commands |
| 62 | -------------------------- |
| 63 | |
| 64 | - pinmon (enabled by CONFIG_CMD_PINMON) |
| 65 | shows the boot mode pins that has been latched at the power-on reset |
| 66 | |
| 67 | - ddrphy (enabled by CONFIG_CMD_DDRPHY_DUMP) |
| 68 | shows the DDR PHY parameters set by the PHY training |
| 69 | |
| 70 | |
| 71 | Supported devices |
| 72 | ----------------- |
| 73 | |
| 74 | - UART (on-chip) |
| 75 | - NAND |
| 76 | - USB (2.0) |
| 77 | - LAN (on-board SMSC9118) |
| 78 | - I2C |
| 79 | - EEPROM (connected to the on-board I2C bus) |
| 80 | - Support card (SRAM, NOR flash, some peripherals) |
| 81 | |
