- Itsy is a research project done by the Western Research Lab, and Systems
- Research Center in Palo Alto, CA. The Itsy project is one of several
- research projects at Compaq that are related to pocket computing.
- For more information, see:

- Notes on initial 2.4 Itsy support (8/27/2000) :
- The port was done on an Itsy version 1.5 machine with a daughtercard with
- 64 Meg of DRAM and 32 Meg of Flash. The initial work includes support for
- serial console (to see what you're doing). No other devices have been
- enabled.
- To build, do a "make menuconfig" (or xmenuconfig) and select Itsy support.
- Disable Flash and LCD support. and then do a make dep and a make zImage.
- Finally, you will need to cd to arch/arm/boot/tools and execute a make there
- to build the params-itsy program used to boot the kernel.
- In order to install the port of 2.4 to the itsy, You will need to set the
- configuration parameters in the monitor as follows:
- Arg 1:0x08340000, Arg2: 0xC0000000, Arg3:18 (0x12), Arg4:0
- Make sure the start-routine address is set to 0x00060000.
- Next, flash the params-itsy program to 0x00060000 ("p 1 0x00060000" in the
- flash menu) Flash the kernel in arch/arm/boot/zImage into 0x08340000
- ("p 1 0x00340000"). Finally flash an initial ramdisk into 0xC8000000
- ("p 2 0x0") We used ramdisk-2-30.gz from the 0.11 version directory on
- handhelds.org.
- The serial connection we established was at:
- 8-bit data, no parity, 1 stop bit(s), 115200.00 b/s. in the monitor, in the
- params-itsy program, and in the kernel itself. This can be changed, but
- not easily. The monitor parameters are easily changed, the params program
- setup is assembly outl's, and the kernel is a configuration item specific to
- the itsy. (i.e. grep for CONFIG_SA1100_ITSY and you'll find where it is.)
- This should get you a properly booting 2.4 kernel on the itsy.
