Message-ID: <395615548.23030@tsinghua.org.cn> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de Hi,Denk, I resolved the 1GB DDR problem, the reason is that I did not define the CONFIG_VERY_BIG_RAM. The u-boot-1.2.0 will visit the address above 0x10000000(256MB) if this CONFIG_VERY_BIG_RAM is not defined,then the u-boot-1.2.0 is dead. Thank you very much. >From: Wolfgang Denk >Reply-To: >To: >Subject: Re: [U-Boot-Users] the question about u-boot for 1GB DDR-1? >Date:Tue, 20 Nov 2007 09:59:55 +0100 > >In message <395543860.30931@tsinghua.org.cn> you wrote: >> I plug in 1GB DDR-1 on DIMM-184 slot, my cpu is MPC8360, the u-boot just only >> visit the address from 0x00000000 to 0x10000000(256MB), it can not visit the >> address above 0x10000000, could you tell me why? and how to reslove this problem? > >This has been recently dicussed here, please see the archive. > >What exactly is your problem?
