ROM Monitor <br />If you're using custom hardware, you'll need a ROM monitor to help bring it <br />up. A monitor generally provides a simple command prompt, with options for r <br />eading/writing memory and perhaps some power-on testing facilities which are <br /> useful before the kernel boots. <br />ROM monitors invariably include boot loader functionality, but if your devic <br />e goes into production you may want a standalone boot loader or a stripped-d <br />own ROM monitor. There are several available on the net: <br />8.1 PPCBOOT <br /><a href="http://ppcboot.sourceforge.net/">http://ppcboot.sourceforge.net/</a> <br />This is an actively developed ROM monitor and Linux boot loader ideal for cu <br />stom boards, derived from 8xxROM and FADSROM. It includes support for BOOTP, <br /> RARP and TFTP image downloading and booting. <br />8.2 LiMon <br /><a href="http://www.thinsys.com/limon.html/">http://www.thinsys.com/limon.html/</a> <br />The Linux Monitor (LiMon) is a low level system start utility for the SBC826 <br />0. It also includes BOOTP and TFTP support. <br />8.3 PMON/2000 <br /><a href="http://pmon.groupbsd.org/">http://pmon.groupbsd.org/</a> <br />The PMON/2000 BootROM Monitor (PMON/2000) permits full-featured debugging to <br /> be performed on a target board that has a serial port, 512KB of ROM, and 12 <br />8KB of RAM that can be dedicated to the Prom Monitor software. <br />8.4 PPCForth <br /><a href="http://ppcforth.sourceforge.net/">http://ppcforth.sourceforge.net/</a> <br />It is currently targeted for the IBM 403, 8xx is a goal for the future. It i <br />s rom-able so you can boot directly from it, and has some ifdef's to slim th <br />e code down to as little as 10K or as large as 30K. It accepts S records ove <br />r the serial port for loading other software. Unfortunately it is written in <br /> assembly, but then it's really small and is released under the GPL. It is a <br /> small implementation of FORTH which is handy for testing and small programs <br />, although the author went overboard and included multitasking and a lot of <br />low-level device control words. <br />8.5 DINK32 <br /><a href="http://www.mot.com/SPS/PowerPC/teksupport/tools/DINK32/VERSION12/dinkindex.h">http://www.mot.com/SPS/PowerPC/teksupport/tools/DINK32/VERSION12/dinkindex.h</a> <br />tm <br />8.6 8xxROM <br /><a href="http://www.s4l.de/powerpc.html">http://www.s4l.de/powerpc.html</a> <br />Derived from FADSROM. No longer actively developed, and only really of histo <br />rical interest as it's superceeded by ppcboot. <br />8.7 FADSROM <br />An old ROM monitor and loader written for the FADS board: <a href="http://lists.linux">http://lists.linux</a> <br />ppc.org/listarcs/linuxppc-embedded/199912/msg00045.html <br />It's now superceeded by ppcboot. <br />---------------------------------------------------------------------------- <br />---- <br />Next Previous Contents <br /> <br />-- <br /> <br />※ 來源:·BBS 水木清華站 smth.org·[FROM: 166.111.161.8] <br /><a href="00000007.htm">上一篇</a><a href="javascript:history.go(-1)">返回上一頁</a><a href="index.htm">回到目錄</a><a href="#top">回到頁首</a><a href="00000009.htm">下一篇</a></h1></center><center><h1>BBS 水木清華站∶精華區</h1></center></body></html>?? 快捷鍵說明
