| 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. |

| 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 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. |
