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 ! + |
