Compile the source
|
||||
------------------
|
||||
|
||||
sLD3 reference board:
|
||||
$ make uniphier_sld3_defconfig
|
||||
$ make CROSS_COMPILE=arm-linux-gnueabihf-
|
||||
The source can be configured and built with the following commands:
|
||||
|
||||
LD4 reference board:
|
||||
$ make uniphier_ld4_sld8_defconfig
|
||||
$ make CROSS_COMPILE=arm-linux-gnueabihf-
|
||||
$ make <defconfig>
|
||||
$ make CROSS_COMPILE=<toolchain-prefix> DEVICE_TREE=<device-tree>
|

sLD8 reference board:
|
||||
$ make uniphier_ld4_sld8_defconfig
|
||||
$ make CROSS_COMPILE=arm-linux-gnueabihf- DEVICE_TREE=uniphier-sld8-ref
|
||||
The recommended <toolchain-prefix> is `arm-linux-gnueabihf-` for 32bit SoCs,
|
||||
`aarch64-linux-gnu-` for 64bit SoCs, but you may wish to change it to use your
|
||||
favorite compiler.
|
||||
|
||||
Pro4 reference board:
|
||||
$ make uniphier_pro4_defconfig
|
||||
$ make CROSS_COMPILE=arm-linux-gnueabihf-
|
||||
The following tables show <defconfig> and <device-tree> for each board.

LD11 reference | uniphier_v8_defconfig | uniphier-ld11-ref

For example, to compile the source for PXs2 Vodka board, run the following:
|
||||
|
||||
Pro5 4KBOX Board:
|
||||
$ make uniphier_pxs2_ld6b_defconfig
|
||||
$ make CROSS_COMPILE=arm-linux-gnueabihf- DEVICE_TREE=uniphier-pro5-4kbox
|
||||
$ make CROSS_COMPILE=arm-linux-gnueabihf- DEVICE_TREE=uniphier-pxs2-vodka
|
||||
|
||||
PXs2 Gentil board:
|
||||
$ make uniphier_pxs2_ld6b_defconfig
|
||||
$ make CROSS_COMPILE=arm-linux-gnueabihf- DEVICE_TREE=uniphier-pxs2-gentil
|
||||
The device tree marked as (default) can be omitted. `uniphier-pxs2-vodka` is
|
||||
the default device tree for the configuration `uniphier_pxs2_ld6b_defconfig`,
|
||||
so the following gives the same result.
|
||||
|
||||
PXs2 Vodka board:
|
||||
$ make uniphier_pxs2_ld6b_defconfig
|
||||
$ make CROSS_COMPILE=arm-linux-gnueabihf-
|
||||
|
||||
LD6b reference board:
|
||||
$ make uniphier_pxs2_ld6b_defconfig
|
||||
$ make CROSS_COMPILE=arm-linux-gnueabihf- DEVICE_TREE=uniphier-ld6b-ref
|
||||
|
||||
LD11 reference board:
|
||||
$ make uniphier_v8_defconfig
|
||||
$ make CROSS_COMPILE=aarch64-linux-gnu- DEVICE_TREE=uniphier-ld11-ref
|
||||
Booting 32bit SoC boards
|
||||
------------------------
|
||||
|
||||
LD20 reference board:
|
||||
$ make uniphier_v8_defconfig
|
||||
$ make CROSS_COMPILE=aarch64-linux-gnu-
|
||||
The build command will generate the following:
|
||||
- u-boot.bin
|
||||
- spl/u-boot.bin
|
||||
|
||||
PXs3 reference board:
|
||||
$ make uniphier_v8_defconfig
|
||||
$ make CROSS_COMPILE=aarch64-linux-gnu- DEVICE_TREE=uniphier-pxs3-ref
|
||||
|
||||
You may wish to change the "CROSS_COMPILE=..." to use your favorite compiler.
|
||||
|
||||
|
||||
Burn U-Boot images to NAND
|
||||
--------------------------
|
||||
|
||||
Write the following to the NAND device:
|
||||
U-Boot can boot UniPhier 32bit SoC boards by itself. Flash the generated images
|
||||
to the storage device (NAND or eMMC) on your board.
|
||||
|
||||
- spl/u-boot-spl.bin at the offset address 0x00000000
|
||||
- u-boot.bin at the offset address 0x00020000
|
||||
|
||||
or
|
||||
The `u-boot-with-spl.bin` is the concatenation of the two (with appropriate
|
||||
padding), so you can also do:
|
||||
|
||||
- u-boot-with-spl.bin at the offset address 0x00000000
|
||||
|
||||
If a TFTP server is available, the images can be easily updated.
|
||||
Just copy the u-boot-spl.bin and u-boot.bin to the TFTP public directory,
|
||||
and then run the following command at the U-Boot command line:
|
||||
and run the following command at the U-Boot command line:
|
||||
|
||||
=> run nandupdate
|
||||
To update the images in NAND:
|
||||
|
||||
=> run nandupdate
|
||||
|
||||
To update the images in eMMC:
|
||||
|
||||
=> run emmcupdate
|
||||
|
||||
|
||||
Burn U-Boot images to eMMC
|
||||
--------------------------
|
||||
Booting 64bit SoC boards
|
||||
------------------------
|
||||
|
||||
Write the following to the Boot partition 1 of the eMMC device:
|
||||
The build command will generate the following:
|
||||
- u-boot.bin
|
||||
|
||||
- spl/u-boot-spl.bin at the offset address 0x00000000
|
||||
- u-boot.bin at the offset address 0x00020000
|
||||
However, U-Boot is not the first stage loader for UniPhier 64bit SoC boards.
|
||||
U-Boot serves as a non-secure boot loader loaded by [ARM Trusted Firmware],
|
||||
so you need to provide the `u-boot.bin` to the build command of ARM Trusted
|
||||
Firmware.
|
||||
|
||||
or
|
||||
|
||||
- u-boot-with-spl.bin at the offset address 0x00000000
|
||||
|
||||
If a TFTP server is available, the images can be easily updated.
|
||||
Just copy the u-boot-spl.bin and u-boot.bin to the TFTP public directory,
|
||||
and then run the following command at the U-Boot command line:
|
||||
|
||||
=> run emmcupdate
