What's different between CONFIG_OF_LIBFDT and CONFIG_OF_FLAT_TREE?<br>My board is mpc8641d and u-boot version is 1.3.1.<br>I f I define CONFIG_OF_FLAT_TREE,and u-boot command bootm will call ft_setup() function, and how is it work?I found DTS files under kernel /arch/powerpc/sysDev directory,Could you give me some advice how to build it?<br><br>Thanks,<br><br>Jie<br><br><b><i>Jerry Van Baren <gerald.vanbaren@ge.com></i></b> wrote:<blockquote class="replbq" style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px; padding-left: 5px;"> jie han wrote:<br>> I define CONFIG_OF_FLAT_TREE support under u-boot.I just want to know <br>> how can I get/set the third address(the address of the device-tree blob) <br>> that we will use at bootm command?Thanks ahead,<br>> <br>> Sincerely,<br>> Jie<br><br>Hi Jie,<br><br>Board and processor are???

Example FDT sources <br>and the device tree compiler itself are now part of the linux kernel <br>sources.<br><br>Good luck,<br>gvb<br><br>-------------------------------------------------------------------------<br>Check out the new SourceForge.net Marketplace.<br>It's the best place to buy or sell services for<br>just about anything Open Source.<br>http://ad.doubleclick.net/clk;164216239;13503038;w?http://sf.net/marketplace<br>_______________________________________________<br>U-Boot-Users mailing
