Hi Thomas<br><br>Thank you so much for your nice explanation!<br>Yes I have misunderstood about ARM. <br>Like you said, it is a general architecture.<br><br>I will figure out the hardware board name from my headquater company.<br><br>But I have a doubt about the boads that U-Boot can deal with.<br>You told me that there thousands of different boards. But how<br>can U-Boot know these board names? And how can U-Boot know<br>there are new boards that come out?<br><br>Thanks<br>Terry<br><br>> Date: Mon, 13 Sep 2010 20:30:30 +0200<br>> From: thomas.petazzoni@free-electrons.com<br>> To: buildroot@busybox.net<br>> Subject: Re: [Buildroot] Build error: No rule to make target `ubootboard_config'<br>> <br>> On Tue, 14 Sep 2010 02:51:42 +0900<br>> S W <sw18@hotmail.co.jp> wrote:<br>> <br>> > I am trying to build a Uboot loader for ARM.<br>> <br>> "ARM" is a very general core architecture.

See include/configs/ in U-Boot<br>> sources for the valid board names in U-Boot.<br>> <
