Message-ID: <395543860.30931@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 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?
