Hello, Haven't tried using u-boot with these boards, but here are couple earlier postings to this list (sorry if you have look through them already):
-------- Original Message -------- Subject: Re: ML403 patch for UBOOT Date: Mon, 25 Sep 2006 09:19:10 -0700 From: Peter Ryser <[EMAIL PROTECTED]> To: [email protected] You might want to start with XAPP542 http://direct.xilinx.com/bvdocs/appnotes/xapp542.pdf http://direct.xilinx.com/bvdocs/appnotes/xapp542.zip The zip file includes the U-Boot patch for Linux kernel 2.4. - Peter -------- End of Original Message -------- -------- Original Message -------- Subject: Re: Led astray? Xilinx ml410 + u-boot + Linux? Date: Thu, 01 Feb 2007 06:57:50 -0800 From: Peter Ryser <[EMAIL PROTECTED]> To: [email protected] Joe, please have a look at http://www.xilinx.com/ml410-p. The pages do contain information, documentation, and examples on how to use U-Boot and Linux 2.4 on the ML410. <snip> -------- End of Original Message -------- For me this sounds like 1) patching kernel is required to get the correct params from u-boot 2) Xilinx has the recipes for 2.4 kernel 3) there is no ready-to-use recipe for 2.6 kernel, but it should not be too difficult to adapt the one for 2.4 kernel Thanks, Andrei Leonid wrote: > Hi: > > I'm trying to bring up Linux on Xilinx ML403 reference board. > > I took 2.6.19.2 kernel from DENX.
