1 | Brutus is an evaluation platform for the SA1100 manufactured by Intel. |
2 | For more details, see: |
3 | |
4 | http://developer.intel.com/design/strong/applnots/sa1100lx/getstart.htm |
5 | |
6 | To compile for Brutus, you must issue the following commands: |
7 | |
8 | make brutus_config |
9 | make config |
10 | [accept all the defaults] |
11 | make zImage |
12 | |
13 | The resulting kernel will end up in linux/arch/arm/boot/zImage. This file |
14 | must be loaded at 0xc0008000 in Brutus's memory and execution started at |
15 | 0xc0008000 as well with the value of registers r0 = 0 and r1 = 16 upon |
16 | entry. |
17 | |
18 | But prior to execute the kernel, a ramdisk image must also be loaded in |
19 | memory. Use memory address 0xd8000000 for this. Note that the file |
20 | containing the (compressed) ramdisk image must not exceed 4 MB. |
21 | |
22 | Typically, you'll need angelboot to load the kernel. |
23 | The following angelboot.opt file should be used: |
24 | |
25 | ----- begin angelboot.opt ----- |
26 | base 0xc0008000 |
27 | entry 0xc0008000 |
28 | r0 0x00000000 |
29 | r1 0x00000010 |
30 | device /dev/ttyS0 |
31 | options "9600 8N1" |
32 | baud 115200 |
33 | otherfile ramdisk_img.gz |
34 | otherbase 0xd8000000 |
35 | ----- end angelboot.opt ----- |
36 | |
37 | Then load the kernel and ramdisk with: |
38 | |
39 | angelboot -f angelboot.opt zImage |
40 | |
41 | The first Brutus serial port (assumed to be linked to /dev/ttyS0 on your |
42 | host PC) is used by angel to load the kernel and ramdisk image. The serial |
43 | console is provided through the second Brutus serial port. To access it, |
44 | you may use minicom configured with /dev/ttyS1, 9600 baud, 8N1, no flow |
45 | control. |
46 | |
47 | Currently supported: |
48 | - RS232 serial ports |
49 | - audio output |
50 | - LCD screen |
51 | - keyboard |
52 | |
53 | The actual Brutus support may not be complete without extra patches. |
54 | If such patches exist, they should be found from |
55 | ftp.netwinder.org/users/n/nico. |
56 | |
57 | A full PCMCIA support is still missing, although it's possible to hack |
58 | some drivers in order to drive already inserted cards at boot time with |
59 | little modifications. |
60 | |
61 | Any contribution is welcome. |

65 | Have Fun ! |
