   5
   6         S3 is used to set CONFIG_SYS_RESET_SOURCE.
   7
   8         To boot the image at 0xFE000000 in NOR flash, use these DIP
   9         switch settings for S3 S4:
  10
  11         +------+        +------+
  12         |      |        | **** |
  13         | **** |        |      |
  14         +------+ ON     +------+ ON
  15           4321            4321
  16         (where the '*' indicates the position of the tab of the switch.)

  18 2.      Memory Map
  19         The memory map looks like this:
  20
  21         0x0000_0000     0x07ff_ffff     DDR              128M
  22         0x8000_0000     0x8fff_ffff     PCI MEM          256M
  23         0x9000_0000     0x9fff_ffff     PCI_MMIO         256M
  24         0xe000_0000     0xe00f_ffff     IMMR             1M
  25         0xe200_0000     0xe20f_ffff     PCI IO           16M
  26         0xe280_0000     0xe280_7fff     NAND FLASH (CS1) 32K
  27         0xf000_0000     0xf001_ffff     VSC7385 (CS2)    128K
  28         0xfa00_0000     0xfa00_7fff     Board Status/    32K
  29                                         LED Control (CS3)
  30         0xfe00_0000     0xfe7f_ffff     NOR FLASH (CS0)  8M

  32 3.      Definitions
  33
  34 3.1     Explanation of NEW definitions in:
  35
  36         include/configs/MPC8313ERDB.h
  37
  38         CONFIG_MPC83xx          MPC83xx family
  39         CONFIG_MPC831x          MPC831x specific
  40         CONFIG_MPC8313ERDB      MPC8313ERDB board specific
  41
  42 4.      Compilation
  43
  44         Assuming you're using BASH (or similar) as your shell:
  45
  46         export CROSS_COMPILE=your-cross-compiler-prefix-
  47         make distclean
  48         make MPC8313ERDB_33_config
  49         (or make MPC8313ERDB_66_config, depending on the speed of
  50          the oscillator on your board)
  51         make
  52
  53 5.      Downloading and Flashing Images
  54
  55 5.1     Reflash U-boot Image using U-boot
  56
  57         =>run tftpflash
  58
  59         You may want to try
  60         =>tftpboot $loadaddr $uboot
  61         first, to make sure that the TFTP load will succeed before it
  62         goes ahead and wipes out your current firmware.  And of course,
  63         have an alternate means of programming the flash available
  64         if the new u-boot doesn't boot.
  65
  66 5.2     Downloading and Booting Linux Kernel
  67
  68         Ensure that all networking-related environment variables are set
  69         properly (including ipaddr, serverip, gatewayip (if needed),
  70         netmask, ethaddr, eth1addr, rootpath (if using NFS root),
  71         fdtfile, and bootfile).
  72
  73         Then, do one of the following, depending on whether you
  74         want an NFS root or a ramdisk root:
  75
  76         =>run nfsboot
  77         or
  78         =>run ramboot
  79
  80 6       Notes
  81
  82         Booting from NAND flash is not yet supported.
  83         The console baudrate for MPC8313ERDB is 115200bps.
