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/

56 $ make uniphier_pxs2_ld6b_defconfig
57 $ make CROSS_COMPILE=arm-linux-gnueabi-
59 PH1-LD6b reference board:
60 $ make uniphier_pxs2_ld6b_defconfig
61 $ make CROSS_COMPILE=arm-linux-gnueabi- DEVICE_TREE=uniphier-ph1-ld6b-ref
63 You may wish to change the "CROSS_COMPILE=arm-linux-gnueabi-"
64 to use your favorite compiler.
67 Burn U-Boot images to NAND
68 --------------------------
70 Write two files to the NAND device as follows:
71 - spl/u-boot-spl.bin at the offset address 0x00000000
72 - u-boot.img at the offset address 0x00010000
74 If a TFTP server is available, the images can be easily updated.
75 Just copy the u-boot-spl-dtb.bin and u-boot-dtb.img to the TFTP public
76 directory, and then run the following command at the U-Boot command line:
81 Burn U-Boot images to eMMC
82 --------------------------
84 Write two files to the Boot partition 1 of the eMMC device as follows:
85 - spl/u-boot-spl.bin at the offset address 0x00000000
86 - u-boot.img at the offset address 0x00010000
88 If a TFTP server is available, the images can be easily updated.
89 Just copy the u-boot-spl-dtb.bin and u-boot-dtb.img to the TFTP public
90 directory, and then run the following command at the U-Boot command line:
95 UniPhier specific commands
96 --------------------------
98 - pinmon (enabled by CONFIG_CMD_PINMON)
99 shows the boot mode pins that has been latched at the power-on reset
101 - ddrphy (enabled by CONFIG_CMD_DDRPHY_DUMP)
102 shows the DDR PHY parameters set by the PHY training
114 - LAN (on-board SMSC9118)
116 - EEPROM (connected to the on-board I2C bus)
117 - Support card (SRAM, NOR flash, some peripherals)
123 The recommended bit switch settings are as follows:
125 SW2 OFF(1)/ON(0) Description
126 ------------------------------------------
129 bit 3 <---- SoC Bus Width 16/32
130 bit 4 <---- SERIAL_SEL[0]
131 bit 5 ----> SERIAL_SEL[1]
132 bit 6 ----> BOOTSWAP_EN
134 bit 8 <---- SOC_SERIAL_DISABLE
136 SW8 OFF(1)/ON(0) Description
137 ------------------------------------------
138 bit 1 <---- CS1_SPLIT
140 bit 3 <---- CASE10_ON
141 bit 4 Don't Care Reserve
142 bit 5 Don't Care Reserve
143 bit 6 Don't Care Reserve
145 bit 8 ----> FLASHBUS32_16
147 The BKSZ[1:0] specifies the address range of memory slot and peripherals
150 BKSZ Description RAM slot Peripherals
151 --------------------------------------------------------------------
152 0b00 15MB RAM / 1MB Peri 00000000-00efffff 00f00000-00ffffff
153 0b01 31MB RAM / 1MB Peri 00000000-01efffff 01f00000-01ffffff
154 0b10 64MB RAM / 1MB Peri 00000000-03efffff 03f00000-03ffffff
155 0b11 127MB RAM / 1MB Peri 00000000-07efffff 07f00000-07ffffff
157 Set BSKZ[1:0] to 0b01 for U-Boot.
158 This mode is the most handy because EA[24] is always supported by the save pin
159 mode of the system bus. On the other hand, EA[25] is not supported for some
160 newer SoCs. Even if it is, EA[25] is not connected on most of the boards.
