-Brutus is an evaluation platform for the SA1100 manufactured by Intel.
-For more details, see:
-
-http://developer.intel.com
-
-To compile for Brutus, you must issue the following commands:
-
- make brutus_config
- make config
- [accept all the defaults]
- make zImage
-
-The resulting kernel will end up in linux/arch/arm/boot/zImage. This file
-must be loaded at 0xc0008000 in Brutus's memory and execution started at
-0xc0008000 as well with the value of registers r0 = 0 and r1 = 16 upon
-entry.
-
-But prior to execute the kernel, a ramdisk image must also be loaded in
-memory. Use memory address 0xd8000000 for this. Note that the file
-containing the (compressed) ramdisk image must not exceed 4 MB.
-
-Typically, you'll need angelboot to load the kernel.
-The following angelboot.opt file should be used:
-
------ begin angelboot.opt -----
-base 0xc0008000
-entry 0xc0008000
-r0 0x00000000
-r1 0x00000010
-device /dev/ttyS0
-options "9600 8N1"
-baud 115200
-otherfile ramdisk_img.gz
-otherbase 0xd8000000
------ end angelboot.opt -----
-
-Then load the kernel and ramdisk with:
-
- angelboot -f angelboot.opt zImage
-
-The first Brutus serial port (assumed to be linked to /dev/ttyS0 on your
-host PC) is used by angel to load the kernel and ramdisk image. The serial
-console is provided through the second Brutus serial port. To access it,
-you may use minicom configured with /dev/ttyS1, 9600 baud, 8N1, no flow
-control.
-
-Currently supported:
- - RS232 serial ports
- - audio output
- - LCD screen
- - keyboard
-
-The actual Brutus support may not be complete without extra patches.
-If such patches exist, they should be found from
-ftp.netwinder.org/users/n/nico.
-
-A full PCMCIA support is still missing, although it's possible to hack
-some drivers in order to drive already inserted cards at boot time with
-little modifications.
-
-Any contribution is welcome.
-
-Please send patches to nico@fluxnic.net
-
-Have Fun !
