| U-Boot for UniPhier SoC family |
| ============================== |
| |
| |
| Tested toolchains |
| ----------------- |
| |
| (a) Ubuntu packages (CROSS_COMPILE=arm-linux-gnueabi-) |
| |
| If you are building U-Boot on Ubuntu, its standard package is recommended. |
| You can install it as follows: |
| |
| $ sudo apt-get install gcc-arm-linux-gnueabi- |
| |
| (b) Linaro compilers (CROSS_COMPILE=arm-linux-gnueabihf-) |
| |
| You can download pre-built toolchains from: |
| |
| http://www.linaro.org/downloads/ |
| |
| (c) kernel.org compilers (CROSS_COMPILE=arm-unknown-linux-gnueabi-) |
| |
| You can download pre-built toolchains from: |
| |
| ftp://www.kernel.org/pub/tools/crosstool/files/bin/ |
| |
| |
| Compile the source |
| ------------------ |
| |
| PH1-sLD3 reference board: |
| $ make uniphier_sld3_defconfig |
| $ make CROSS_COMPILE=arm-linux-gnueabi- |
| |
| PH1-LD4 reference board: |
| $ make uniphier_ld4_sld8_defconfig |
| $ make CROSS_COMPILE=arm-linux-gnueabi- |
| |
| PH1-sLD8 reference board: |
| $ make uniphier_ld4_sld8_defconfig |
| $ make CROSS_COMPILE=arm-linux-gnueabi- DEVICE_TREE=uniphier-ph1-sld8-ref |
| |
| PH1-Pro4 reference board: |
| $ make uniphier_pro4_defconfig |
| $ make CROSS_COMPILE=arm-linux-gnueabi- |
| |
| PH1-Pro5 4KBOX Board: |
| $ make uniphier_pro5_defconfig |
| $ make CROSS_COMPILE=arm-linux-gnueabi- |
| |
| ProXstream2 Gentil board: |
| $ make uniphier_pxs2_ld6b_defconfig |
| $ make CROSS_COMPILE=arm-linux-gnueabi- DEVICE_TREE=uniphier-proxstream2-gentil |
| |
| ProXstream2 Vodka board: |
| $ make uniphier_pxs2_ld6b_defconfig |
| $ make CROSS_COMPILE=arm-linux-gnueabi- |
| |
| PH1-LD6b reference board: |
| $ make uniphier_pxs2_ld6b_defconfig |
| $ make CROSS_COMPILE=arm-linux-gnueabi- DEVICE_TREE=uniphier-ph1-ld6b-ref |
| |
| You may wish to change the "CROSS_COMPILE=arm-linux-gnueabi-" |
| to use your favorite compiler. |
| |
| |
| Burn U-Boot images to NAND |
| -------------------------- |
| |
| Write two files to the NAND device as follows: |
| - spl/u-boot-spl-dtb.bin at the offset address 0x00000000 |
| - u-boot-dtb.img at the offset address 0x00010000 |
| |
| If a TFTP server is available, the images can be easily updated. |
| Just copy the u-boot-spl-dtb.bin and u-boot-dtb.img to the TFTP public |
| directory, and then run the following command at the U-Boot command line: |
| |
| => run nandupdate |
| |
| |
| UniPhier specific commands |
| -------------------------- |
| |
| - pinmon (enabled by CONFIG_CMD_PINMON) |
| shows the boot mode pins that has been latched at the power-on reset |
| |
| - ddrphy (enabled by CONFIG_CMD_DDRPHY_DUMP) |
| shows the DDR PHY parameters set by the PHY training |
| |
| |
| Supported devices |
| ----------------- |
| |
| - UART (on-chip) |
| - NAND |
| - USB 2.0 (EHCI) |
| - USB 3.0 (xHCI) |
| - LAN (on-board SMSC9118) |
| - I2C |
| - EEPROM (connected to the on-board I2C bus) |
| - Support card (SRAM, NOR flash, some peripherals) |
| |
| |
| Micro Support Card |
| ------------------ |
| |
| The recommended bit switch settings are as follows: |
| |
| SW2 OFF(1)/ON(0) Description |
| ------------------------------------------ |
| bit 1 <---- BKSZ[0] |
| bit 2 ----> BKSZ[1] |
| bit 3 <---- SoC Bus Width 16/32 |
| bit 4 <---- SERIAL_SEL[0] |
| bit 5 ----> SERIAL_SEL[1] |
| bit 6 ----> BOOTSWAP_EN |
| bit 7 <---- CS1/CS5 |
| bit 8 <---- SOC_SERIAL_DISABLE |
| |
| SW8 OFF(1)/ON(0) Description |
| ------------------------------------------ |
| bit 1 ----> CS1_SPLIT |
| bit 2 <---- CASE9_ON |
| bit 3 <---- CASE10_ON |
| bit 4 Don't Care Reserve |
| bit 5 Don't Care Reserve |
| bit 6 Don't Care Reserve |
| bit 7 ----> BURST_EN |
| bit 8 ----> FLASHBUS32_16 |
| |
| The BKSZ[1:0] specifies the address range of memory slot and peripherals |
| as follows: |
| |
| BKSZ Description RAM slot Peripherals |
| -------------------------------------------------------------------- |
| 0b00 15MB RAM / 1MB Peri 00000000-00efffff 00f00000-00ffffff |
| 0b01 31MB RAM / 1MB Peri 00000000-01efffff 01f00000-01ffffff |
| 0b10 64MB RAM / 1MB Peri 00000000-03efffff 03f00000-03ffffff |
| 0b11 127MB RAM / 1MB Peri 00000000-07efffff 07f00000-07ffffff |
| |
| Set BSKZ[1:0] to 0b01 for U-Boot. |
| This mode is the most handy because EA[24] is always supported by the save pin |
| mode of the system bus. On the other hand, EA[25] is not supported for some |
| newer SoCs. Even if it is, EA[25] is not connected on most of the boards. |
