| # global_env |
| # |
| # file used by Hymod boards to initialise the u-boot non-volatile |
| # environment when u-boot is first run (it determines this by the |
| # absence of the environment variable "global_env_loaded") |
| # |
| # format of this file is: |
| # |
| # 1. blank lines and lines beginning with '#' are ignored |
| # 2. all other lines must have the form <name>=<value> |
| # 3. if a percent appears anywhere, it is replaced like so: |
| # |
| # %s serial number of the main board (10 digit zero filled) |
| # %S serial number of the main board (plain number) |
| # %% a percentage character |
| # ... otherwise the %x is discarded |
| # |
| # if first character in <name> is a dash ('-'), then an existing env var |
| # will not be overwritten (the dash is removed). i.e. it is only set if |
| # it does not exist |
| # |
| # if last character in <name> is a plus ('+'), then <value> will be appended |
| # to any existing env var (the plus is ignored). Duplicates of <value> are |
| # removed. |
| # |
| # similarly, if the last character in <name> is a minus ('-'), then any |
| # occurences of <value> in the current value of <name> will removed (the |
| # minus is ignored). |
| # |
| # leading and trailing whitespace is removed in both <name> and <value> |
| # (after processing any initial or final plus/minus in <name>). |
| # |
| |
| # MISCELLANEOUS PARAMETERS |
| |
| # version must always come first |
| version=4 |
| |
| # set the ip address based on the main board serial number |
| ipaddr=192.168.1.%S |
| serverip=192.168.1.254 |
| |
| # stop auto execute after tftp (not a very good name really) |
| autostart=no |
| |
| # setting this to "yes" forces the global_env file to be loaded and processed |
| # if the current version is different to the version in the file |
| always_check_env=no |
| |
| # BOOTING COMMANDS AND PARAMETERS |
| |
| # command to run when "auto-booting" |
| bootcmd=bootm 40080000 |
| |
| # how long the "countdown" to automatically running "bootcmd" is |
| bootdelay=2 |
| |
| # how long before it "times out" console input and attempts to run "bootcmd" |
| bootretry=5 |
| |
| # arguments passed to the boot program (i.e. linux kernel) via register 6 |
| # the linux kernel (v2.4) uses the following registers: |
| # r3 - address of board information structure |
| # r4 - address of initial ramdisk image (0 means no initrd) |
| # r5 - size of initial ramdisk image |
| # r6 - address of command line string |
| -bootargs=root=/dev/mtdblock5 rootfstype=squashfs ro |

| # then our ciscos don't pass packets for 25-30 secs after that, so |
