1 | Itsy is a research project done by the Western Research Lab, and Systems |
2 | Research Center in Palo Alto, CA. The Itsy project is one of several | |
3 | research projects at Compaq that are related to pocket computing. | |

9 | Notes on initial 2.4 Itsy support (8/27/2000) : | |
10 | The port was done on an Itsy version 1.5 machine with a daughtercard with | |
11 | 64 Meg of DRAM and 32 Meg of Flash. The initial work includes support for | |
12 | serial console (to see what you're doing). No other devices have been | |
13 | enabled. | |
14 | ||
15 | To build, do a "make menuconfig" (or xmenuconfig) and select Itsy support. | |
16 | Disable Flash and LCD support. and then do a make zImage. | |
17 | Finally, you will need to cd to arch/arm/boot/tools and execute a make there | |
18 | to build the params-itsy program used to boot the kernel. | |
19 | ||
20 | In order to install the port of 2.4 to the itsy, You will need to set the | |
21 | configuration parameters in the monitor as follows: | |
22 | Arg 1:0x08340000, Arg2: 0xC0000000, Arg3:18 (0x12), Arg4:0 | |
23 | Make sure the start-routine address is set to 0x00060000. | |
24 | ||
25 | Next, flash the params-itsy program to 0x00060000 ("p 1 0x00060000" in the | |
26 | flash menu) Flash the kernel in arch/arm/boot/zImage into 0x08340000 | |
27 | ("p 1 0x00340000"). Finally flash an initial ramdisk into 0xC8000000 | |
28 | ("p 2 0x0") We used ramdisk-2-30.gz from the 0.11 version directory on | |
29 | handhelds.org. | |
30 | ||
31 | The serial connection we established was at: | |
32 | 8-bit data, no parity, 1 stop bit(s), 115200.00 b/s. in the monitor, in the | |
33 | params-itsy program, and in the kernel itself. This can be changed, but | |
34 | not easily. The monitor parameters are easily changed, the params program | |
35 | setup is assembly outl's, and the kernel is a configuration item specific to | |
36 | the itsy. (i.e. grep for CONFIG_SA1100_ITSY and you'll find where it is.) | |
37 | ||

39 | This should get you a properly booting 2.4 kernel on the itsy. |
