Current Version: 191.4 introduced with WebOS 1.4.1
Old version : 145.2.6 introduced with WebOS 1.0.3
Bootie is the stage3 bootloader of webOS devices. It is unpacked from the end of boot.bin, and loaded to **0x82000000** in memory. Bootie looks very similar to iBoot from the iPhoneOS devices.
Getting into bootie mode is as easy as holding the volume-up key while plugging the phone into USB while the phone is in the "off" state. The novaterm/novaproxy programs can then be used to talk to bootie.
Running Bootie commands
The following is an example of using novaterm to run the bootie command "help":
] help
command list:
nduid : get the device id
usb : usb transfer commands
lboot : boot linux image
klog : klog commands
printenv : print all of the environment variables
getenv : read an environment variable
setenv : set an environment variable
reset : reset the device
script : run a script at specified address
run : run a script at from an environment variable
return : return from current script
help : this list
version : get bootie version
battery : battery status (found in webOS 1.4.1 and not in 1.0.3)
charging : commands to set charging states
fsboot : boot current image based on environment
chainboot : boot another bootloader image based on environment
go : Jump to a given address with the given arguments
cpurev : read the cpu revision (found in webOS 1.0.3 but not in 1.4.1)
diag : perform diag operations: write, boot, verify
poweroff : power off completely
The Bootie Environment
The default environment of Pre phones during boot follows:
] getenv
T ? = 0
T chargebypass = 0
T framebuffer = 0x8f600000
T boardtype = castle-dvt3
installer = trenchcoat
T klog_len = 0x100000
T klog_addr = 0x8ff00000
T logofile = boot/logo.tga
T bootaddress = 0x81000000
T bootfile = uImage
T bootfs = ext2
T bootdevice = mmc0p1
T bootargs-ramdisk = root=/dev/ram0 ramdisk=32768 ro
T bootargs = root=b302 rootdelay=2 ro
T bootconsole = tty1
autoboot = fsboot
The boot environment on a TouchPad (3.0.2) follows:
T ? = -1000
T framebuffer = 0x7f600000
installer = trenchcoat
checkbatt = 1
T chargebypass = 1
T klog_len = 0x100000
T klog_addr = 0x7ff00000
T tablet_wod_support = 0x0
T extended_timeout = 0x0
T chainbootdevice = mmc0
T bootaddress = 0x41000000
T bootdevice = mmc0p12
T bootfile = uImage
T bootfs = ext2
T bootargs-ramdisk = root=/dev/ram0 rw
T bootargs = root=/dev/mmcblk0p13 rootwait ro
T bootconsole = ttyS0,115200n8
T autoboot = fsboot
T boardtype = topaz-Wifi-pvt
Additional commands
In addition to the commands listed by the help command displayed above, bootie supports the command get which will return the contents of a file, for example:
novacom get file://klog
