27 # file used by Hymod boards to initialise the u-boot non-volatile
28 # environment when u-boot is first run (it determines this by the
29 # absence of the environment variable "global_env_loaded")
31 # format of this file is:
33 # 1. blank lines and lines beginning with '#' are ignored
34 # 2. all other lines must have the form <name>=<value>
35 # 3. if a percent appears anywhere, it is replaced like so:
37 # %s serial number of the main board (10 digit zero filled)
38 # %S serial number of the main board (plain number)
39 # %% a percentage character
40 # ... otherwise the %x is discarded
42 # if first character in <name> is a dash ('-'), then an existing env var
43 # will not be overwritten (the dash is removed). i.e. it is only set if
46 # if last character in <name> is a plus ('+'), then <value> will be appended
47 # to any existing env var (the plus is ignored). Duplicates of <value> are
50 # similarly, if the last character in <name> is a minus ('-'), then any
51 # occurences of <value> in the current value of <name> will removed (the
54 # leading and trailing whitespace is removed in both <name> and <value>
55 # (after processing any initial or final plus/minus in <name>).
58 # MISCELLANEOUS PARAMETERS
60 # version must always come first
63 # set the ip address based on the main board serial number
65 serverip=192.168.1.254
67 # stop auto execute after tftp (not a very good name really)
70 # setting this to "yes" forces the global_env file to be loaded and processed
71 # if the current version is different to the version in the file
74 # BOOTING COMMANDS AND PARAMETERS
76 # command to run when "auto-booting"
77 bootcmd=bootm 40080000 40200000
79 # how long the "countdown" to automatically running "bootcmd" is
82 # how long before it "times out" console input and attempts to run "bootcmd"
85 # arguments passed to the boot program (i.e. linux kernel) via register 6
86 # the linux kernel (v2.4) uses the following registers:
87 # r3 - address of board information structure
88 # r4 - address of initial ramdisk image (0 means no initrd)
89 # r5 - size of initial ramdisk image
90 # r6 - address of command line string
91 -bootargs=root=/dev/ram rw
93 # these four are for hymod linux intergrated into our Sun network
95 bootargs+=nisclient nisdomain=mlb.dmt.csiro.au nissrvadr=138.194.112.4
99 # start a web server by default
102 # give negotiation time to finish
105 # then our ciscos don't pass packets for 25-30 secs after that, so
106 # pinging the server until it responds prevents network connections
110 # these are old bootargs - we don't need them anymore
111 bootargs-=preload=unix,i2c-cpm,i2c-dev
112 bootargs-=ramdisk_size=32768
113 bootargs-=ramdisk_size=24576
