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)
