   8 * Install U-Boot Source *
   9 -------------------------
  10
  11 To install the full source of u-boot-1.1.6, you need to download following
  12 two files from http://www.ingenic.cn:
  13
  14 * u-boot-1.1.6.tar.bz2: the original u-boot source package.
  15 * u-boot-1.1.6-jz-yyyymmdd.patch.gz: the latest u-boot patch from ingenic.
  16
  17 First, put the u-boot tarball in the working directory and unpack it:
  18
  19     $ tar -xjf u-boot-1.1.6.tar.bz2
  20
  21 Then, apply the patch to the u-boot tree:
  22
  23     $ cd u-boot-1.1.6
  24     $ gzip -cd ../u-boot-1.1.6-jz-yyyymmdd.patch.gz | patch -p1

  28 * Quick Start *
  29 ---------------
  30
  31 To build u-boot-1.1.6, you needs MIPS GCC-3.3.1 or GCC-4.1.2.
  32
  33 This release supports several platforms based on JZSOC. The platform
  34 names are listed below:
  35
  36   - LIBRA: JZ4730 development board
  37   - PMPV1: JZ4730 PMP reference board version 1.x
  38   - PMPV2: JZ4730 PMP reference board version 2.x
  39   - GPS: JZ4730 GPS reference board
  40   - LEO: JZ4740 development board
  41   - PAVO: JZ4740 PMP reference board
  42   - VIRGO: JZ4720 reference board
  43   - DIPPER: JZ4725 reference board
  44
  45 Configure and compile u-boot:
  46
  47 For example,
  48
  49   - Build u-boot.bin for NOR flash boot:
  50
  51     $ make pmpv2_config (JZ4730-based PMP version 2.x board)
  52     $ make pavo_config (JZ4740-based PAVO board)
  53     $ make virgo_config (JZ4720-based VIRGO board)
  54     $ make dipper_config (JZ4725-based DIPPER board)
  55
  56     $ make
  57
  58   - Build u-boot-nand.bin for NAND flash boot:
  59
  60     $ make pmpv2_nand_config (JZ4730-based PMP version 2.x board)
  61     $ make pavo_nand_config (JZ4740-based PAVO board)
  62     $ make virgo_nand_config (JZ4720-based VIRGO board)
  63     $ make dipper_nand_config (JZ4725-based DIPPER board)
  64
  65     $ make
