6-----------------
7
8 (a) Ubuntu packages (CROSS_COMPILE=arm-linux-gnueabi-)
9
10 If you are building U-Boot on Ubuntu, its standard package is recommended.
11 You can install it as follows:
12
13 $ sudo apt-get install gcc-arm-linux-gnueabi-
14
15 (b) Linaro compilers (CROSS_COMPILE=arm-linux-gnueabihf-)

Masahiro Yamadada8d0312015-02-05 14:30:23 +090051You may wish to change the "CROSS_COMPILE=arm-linux-gnueabi-"
52to use your favorite compiler.

55Burn U-Boot images to NAND
56--------------------------
57
58Write two files to the NAND device as follows:
Masahiro Yamada47eb9a82015-08-28 20:13:18 +090059 - spl/u-boot-spl-dtb.bin at the offset address 0x00000000
60 - u-boot-dtb.img at the offset address 0x00010000
Masahiro Yamadada8d0312015-02-05 14:30:23 +090061
62If a TFTP server is available, the images can be easily updated.
Masahiro Yamada47eb9a82015-08-28 20:13:18 +090063Just copy the u-boot-spl-dtb.bin and u-boot-dtb.img to the TFTP public
64directory, and then run the following command at the U-Boot command line:
Masahiro Yamadada8d0312015-02-05 14:30:23 +090065
66 => run nandupdate
67
68
69UniPhier specific commands

71
72 - pinmon (enabled by CONFIG_CMD_PINMON)
73 shows the boot mode pins that has been latched at the power-on reset
74
75 - ddrphy (enabled by CONFIG_CMD_DDRPHY_DUMP)
76 shows the DDR PHY parameters set by the PHY training
77
78
79Supported devices

90
91
Masahiro Yamada58565492015-07-21 14:04:24 +090092Micro Support Card
93------------------
94
95The recommended bit switch settings are as follows:
96
97 SW2 OFF(1)/ON(0) Description
98 ------------------------------------------
99 bit 1 <---- BKSZ[0]
100 bit 2 ----> BKSZ[1]
101 bit 3 <---- SoC Bus Width 16/32
102 bit 4 <---- SERIAL_SEL[0]
103 bit 5 ----> SERIAL_SEL[1]
104 bit 6 ----> BOOTSWAP_EN
105 bit 7 <---- CS1/CS5
106 bit 8 <---- SOC_SERIAL_DISABLE
107
108 SW8 OFF(1)/ON(0) Description
109 ------------------------------------------
110 bit 1 ----> CS1_SPLIT
111 bit 2 <---- CASE9_ON
112 bit 3 <---- CASE10_ON
113 bit 4 Don't Care Reserve
114 bit 5 Don't Care Reserve
115 bit 6 Don't Care Reserve
116 bit 7 ----> BURST_EN
117 bit 8 ----> FLASHBUS32_16
118
119The BKSZ[1:0] specifies the address range of memory slot and peripherals
120as follows:
121
122 BKSZ Description RAM slot Peripherals
123 --------------------------------------------------------------------
124 0b00 15MB RAM / 1MB Peri 00000000-0effffff 0f000000-0fffffff
125 0b01 31MB RAM / 1MB Peri 00000000-1effffff 1f000000-1fffffff
126 0b10 64MB RAM / 1MB Peri 00000000-3effffff 3f000000-3fffffff
127 0b11 127MB RAM / 1MB Peri 00000000-7effffff 7f000000-7fffffff
128
129Set BSKZ[1:0] to 0b01 for U-Boot.
130This mode is the most handy because EA[24] is always supported by the save pin
131mode of the system bus. On the other hand, EA[25] is not supported for some
132newer SoCs. Even if it is, EA[25] is not connected on most of the boards.
