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) |
||||
- LAN (on-board SMSC9118) |
||||
- I2C |
||||
- EEPROM (connected to the on-board I2C bus) |
||||
- Support card (SRAM, NOR flash, some peripherals) |
||||
