The Itsy project is one of several +research projects at Compaq that are related to pocket computing. + +For more information, see: + + http://www.hpl.hp.com/downloads/crl/itsy/ + +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. |
