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 | ||
| 31 | PH1-Pro4: | |
| 32 | $ make ph1_pro4_defconfig | |
| 33 | $ make CROSS_COMPILE=arm-linux-gnueabi- | |
| 34 | ||
| 35 | PH1-LD4: | |
| 36 | $ make ph1_ld4_defconfig | |
| 37 | $ make CROSS_COMPILE=arm-linux-gnueabi- | |
| 38 | ||
| 39 | PH1-sLD8: | |
| 40 | $ make ph1_sld8_defconfig | |
| 41 | $ make CROSS_COMPILE=arm-linux-gnueabi- | |
| 42 | ||
| 43 | You may wish to change the "CROSS_COMPILE=arm-linux-gnueabi-" | |
| 44 | to use your favorite compiler. | |
| 45 | ||
| 46 | ||
| 47 | Burn U-Boot images to NAND | |
| 48 | -------------------------- | |
| 49 | ||
| 50 | Write two files to the NAND device as follows: | |
| 51 | - spl/u-boot-spl.bin at the offset address 0x00000000 | |
| 52 | - u-boot-dtb.img at the offset address 0x00010000 | |
| 53 | ||
| 54 | If a TFTP server is available, the images can be easily updated. | |
| 55 | Just copy the u-boot-spl.bin and u-boot-dtb.img to the TFTP public directory, | |
| 56 | and then run the following command at the U-Boot command line: | |
| 57 | ||
| 58 | => run nandupdate | |
| 59 | ||
| 60 | ||
| 61 | UniPhier specific commands | |
| 62 | -------------------------- | |
| 63 | ||
| 64 | - pinmon (enabled by CONFIG_CMD_PINMON) | |
| 65 | shows the boot mode pins that has been latched at the power-on reset | |
| 66 | ||
| 67 | - ddrphy (enabled by CONFIG_CMD_DDRPHY_DUMP) | |
| 68 | shows the DDR PHY parameters set by the PHY training | |
| 69 | ||
| 70 | ||
| 71 | Supported devices | |
| 72 | ----------------- | |
| 73 | ||
| 74 | - UART (on-chip) | |
| 75 | - NAND | |
| 1e7df7c4 MY |
76 | - USB 2.0 (EHCI) |
| 77 | - USB 3.0 (xHCI) | |
| 7168da16 MY |
78 | - LAN (on-board SMSC9118) |
| 79 | - I2C | |
| 80 | - EEPROM (connected to the on-board I2C bus) | |
| 81 | - Support card (SRAM, NOR flash, some peripherals) | |
