| U-Boot for UniPhier SoC family |
| ============================== |
| |
| |
| Tested toolchains |
| ----------------- |
| |
| (a) Ubuntu packages (CROSS_COMPILE=arm-linux-gnueabi-) |
| |
| If you are building U-Boot on Ubuntu, its standard package is recommended. |
| You can install it as follows: |
| |
| $ sudo apt-get install gcc-arm-linux-gnueabi- |
| |
| (b) Linaro compilers (CROSS_COMPILE=arm-linux-gnueabihf-) |
| |
| You can download pre-built toolchains from: |
| |
| http://www.linaro.org/downloads/ |
| |
| (c) kernel.org compilers (CROSS_COMPILE=arm-unknown-linux-gnueabi-) |
| |
| You can download pre-built toolchains from: |
| |
| ftp://www.kernel.org/pub/tools/crosstool/files/bin/ |
| |
| |
| Compile the source |
| ------------------ |
| |
| PH1-Pro4: |
| $ make ph1_pro4_defconfig |
| $ make CROSS_COMPILE=arm-linux-gnueabi- |
| |
| PH1-LD4: |
| $ make ph1_ld4_defconfig |
| $ make CROSS_COMPILE=arm-linux-gnueabi- |
| |
| PH1-sLD8: |
| $ make ph1_sld8_defconfig |
| $ make CROSS_COMPILE=arm-linux-gnueabi- |
| |
| You may wish to change the "CROSS_COMPILE=arm-linux-gnueabi-" |
| to use your favorite compiler. |
| |
| |
| Burn U-Boot images to NAND |
| -------------------------- |
| |
| Write two files to the NAND device as follows: |
| - spl/u-boot-spl.bin at the offset address 0x00000000 |
| - u-boot-dtb.img at the offset address 0x00010000 |
| |
| If a TFTP server is available, the images can be easily updated. |
| Just copy the u-boot-spl.bin and u-boot-dtb.img to the TFTP public directory, |
| and then run the following command at the U-Boot command line: |
| |
| => run nandupdate |
| |
| |
| UniPhier specific commands |
| -------------------------- |
| |
| - pinmon (enabled by CONFIG_CMD_PINMON) |
| shows the boot mode pins that has been latched at the power-on reset |
| |
| - ddrphy (enabled by CONFIG_CMD_DDRPHY_DUMP) |
| shows the DDR PHY parameters set by the PHY training |
| |
| |
| Supported devices |
| ----------------- |
| |
| - UART (on-chip) |
| - NAND |
| - USB 2.0 (EHCI) |
| - USB 3.0 (xHCI) |
| - LAN (on-board SMSC9118) |
| - I2C |
| - EEPROM (connected to the on-board I2C bus) |
| - Support card (SRAM, NOR flash, some peripherals) |
