1 | U-Boot for UniPhier SoC family |
2 | ============================== | |
3 | ||
4 | ||
5 | Tested toolchains | |
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-) | |
16 | ||
17 | You can download pre-built toolchains from: | |
18 | ||
19 | http://www.linaro.org/downloads/ | |
20 | ||
21 | (c) kernel.org compilers (CROSS_COMPILE=arm-unknown-linux-gnueabi-) | |
22 | ||
23 | You can download pre-built toolchains from: | |
24 | ||
25 | ftp://www.kernel.org/pub/tools/crosstool/files/bin/ | |
26 | ||
27 | ||
28 | Compile the source | |
29 | ------------------ | |
30 | ||
3365b4eb MY |
31 | PH1-sLD3: |
32 | $ make ph1_sld3_defconfig | |
7168da16 MY |
33 | $ make CROSS_COMPILE=arm-linux-gnueabi- |
34 | ||
35 | PH1-LD4: | |
36 | $ make ph1_ld4_defconfig | |
37 | $ make CROSS_COMPILE=arm-linux-gnueabi- | |
38 | ||
3365b4eb MY |
39 | PH1-Pro4: |
40 | $ make ph1_pro4_defconfig | |
41 | $ make CROSS_COMPILE=arm-linux-gnueabi- | |
42 | ||
7168da16 MY |
43 | PH1-sLD8: |
44 | $ make ph1_sld8_defconfig | |
45 | $ make CROSS_COMPILE=arm-linux-gnueabi- | |
46 | ||
28f40d4a MY |
47 | PH1-Pro5: |
48 | $ make ph1_pro5_defconfig | |
49 | $ make CROSS_COMPILE=arm-linux-gnueabi- | |
50 | ||
7168da16 MY |
51 | You may wish to change the "CROSS_COMPILE=arm-linux-gnueabi-" |
52 | to use your favorite compiler. | |
53 | ||
54 | ||
55 | Burn U-Boot images to NAND | |
56 | -------------------------- | |
57 | ||
58 | Write two files to the NAND device as follows: | |
f4e190e3 MY |
59 | - spl/u-boot-spl-dtb.bin at the offset address 0x00000000 |
60 | - u-boot-dtb.img at the offset address 0x00010000 | |
7168da16 MY |
61 | |
62 | If a TFTP server is available, the images can be easily updated. | |
f4e190e3 MY |
63 | Just copy the u-boot-spl-dtb.bin and u-boot-dtb.img to the TFTP public |
64 | directory, and then run the following command at the U-Boot command line: | |
7168da16 MY |
65 | |
66 | => run nandupdate | |
67 | ||
68 | ||
69 | UniPhier specific commands | |
70 | -------------------------- | |
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 | ||
79 | Supported devices | |
80 | ----------------- | |
81 | ||
82 | - UART (on-chip) | |
83 | - NAND | |
1e7df7c4 MY |
84 | - USB 2.0 (EHCI) |
85 | - USB 3.0 (xHCI) | |
7168da16 MY |
86 | - LAN (on-board SMSC9118) |
87 | - I2C | |
88 | - EEPROM (connected to the on-board I2C bus) | |
89 | - Support card (SRAM, NOR flash, some peripherals) | |
90 | ||
91 | ||
62102bee MY |
92 | Micro Support Card |
93 | ------------------ | |
94 | ||
95 | The 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 | ||
119 | The BKSZ[1:0] specifies the address range of memory slot and peripherals | |
120 | as 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 | ||
129 | Set BSKZ[1:0] to 0b01 for U-Boot. | |
130 | This mode is the most handy because EA[24] is always supported by the save pin | |
131 | mode of the system bus. On the other hand, EA[25] is not supported for some | |
132 | newer SoCs. Even if it is, EA[25] is not connected on most of the boards. | |
