1 U-Boot for UniPhier SoC family
2 ==============================
8 (a) Ubuntu packages (CROSS_COMPILE=arm-linux-gnueabi-)
10 If you are building U-Boot on Ubuntu, its standard package is recommended.
11 You can install it as follows:
13 $ sudo apt-get install gcc-arm-linux-gnueabi-
15 (b) Linaro compilers (CROSS_COMPILE=arm-linux-gnueabihf-)
17 You can download pre-built toolchains from:
19 http://www.linaro.org/downloads/
21 (c) kernel.org compilers (CROSS_COMPILE=arm-unknown-linux-gnueabi-)
23 You can download pre-built toolchains from:
25 ftp://www.kernel.org/pub/tools/crosstool/files/bin/
32 $ make ph1_pro4_defconfig
33 $ make CROSS_COMPILE=arm-linux-gnueabi-
36 $ make ph1_ld4_defconfig
37 $ make CROSS_COMPILE=arm-linux-gnueabi-
40 $ make ph1_sld8_defconfig
41 $ make CROSS_COMPILE=arm-linux-gnueabi-
43 You may wish to change the "CROSS_COMPILE=arm-linux-gnueabi-"
44 to use your favorite compiler.
47 Burn U-Boot images to NAND
48 --------------------------
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
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:
61 UniPhier specific commands
62 --------------------------
64 - pinmon (enabled by CONFIG_CMD_PINMON)
65 shows the boot mode pins that has been latched at the power-on reset
67 - ddrphy (enabled by CONFIG_CMD_DDRPHY_DUMP)
68 shows the DDR PHY parameters set by the PHY training
77 - LAN (on-board SMSC9118)
79 - EEPROM (connected to the on-board I2C bus)
80 - Support card (SRAM, NOR flash, some peripherals)
