- Installing 4th Edition Inferno on an IPAQ (21 August 2003)
- This Inferno kernel software is only for the iPAQ 36xx,
- colour models only.
- Of course, since it's Inferno, the existing
- applications, and yours, will run (give or take kernel bugs).
- Suspend/resume is implemented except for PCMCIA.
- (We are doing the work to make it more general.)
- Otherwise the system tries to conserve power in the usual
- ways by going into idle to wait for interrupts and powering
- devices up and down on open and close.
- The following describes loading the Inferno kernel in to the iPAQ.
- This preliminary version has some things hard-wired in to the code
- to run on our wavelan network (see the end of archipaq.c).
- os/init/ipaqinit.b will support a file system (currently dossrv for simplicity)
- running over a Flash Translation Layer on the iPAQ flash.
- Setting up a local file system and loading that onto the iPAQ
- is not discussed here. A separate package will deal with that.
- For development, we generally take the software over the net from
- an Inferno file service (ie, svc/net) running in emu.
- We are providing this iPAQ kernel package to subscribers earlier,
- for the benefit of those subscribers that can make use of it now
- (eg, modify the networking setup to suit their own network).
- A basic local file system package should be available shortly.
- Until it is, if you are not confident you can set up the networking
- or prepare a local file system, you should wait.
- 1. You must first prepare the iPAQ with the handhelds.org bootloader,
- version 2.18.54 (later ones probably work but we haven't yet tried them).
- Use the iPAQ H3600 Linux installation instructions:
- ftp://ftp.handhelds.org/pub/linux/compaq/ipaq/stable/install.html
- Following that procedure will eliminate Windows/CE from the device: if you will need it
- in future, be sure to save the flash images as
- described in the handhelds.org instructions.
- Note that you will also be trusting that they can get you
- back to a working WinCE machine, so be sure to read the handhelds.org
- documents thoroughly in that regard.
- 2. At the end, the instructions say ``At this point you have a working
- bootloader and you are ready to install a Linux distribution''.
- You can install Inferno instead, or several other systems, and
- you can later install them instead of Inferno, since they all use
- the same boot loader.
- 3. A ready-made Inferno kernel is in the file k.gz in this directory
- (os/ipaq1110/k.gz in the Inferno structure). With a 115k serial connection
- to the bootloader established, as described for loading Linux,
- when you tell the bootloader to `load kernel', send k.gz as the
- data file (using the XMODEM protocol as described by Handhelds.org).
- 4. Once the system is running, you can update kernels using Inferno,
- when your file system is taken as `remote' over a wireless connection.
- In an Inferno shell on the device (perhaps using the console serial port
- as a keyboard):
- bind -a '#F' /dev
- echo erase all >/dev/flash/kernelctl
- dd </os/ipaq1110/k.gz -conv sync >/dev/flash/kernel
- or just run
- /os/ipaq1110/upd
- which does that.
