- Brutus is an evaluation platform for the SA1100 manufactured by Intel.
- For more details, see:
- http://developer.intel.com/design/strong/applnots/sa1100lx/getstart.htm
- To compile for Brutus, you must issue the following commands:
- make brutus_config
- make config
- [accept all the defaults]
- make dep
- 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@cam.org
- Have Fun !
