Hi We are running Linux 2.2.13 on our custom embedded MPC850 platform. We are using ppcboot 0.4.1
With 8M configuration everything runs OK. No problems When we extend the SDRAM from 8M to 16M the kernel crashes with 'machine check' exception that caused by 'turn_on_mmu' routine inside head.S file. >From ppcboot we can see all memory area, available to read & write. Do I need to change any additional registers besides OR's & BR's ? We have also changed the refresh rate to meet the increased memory configuration. Any suggestions ? ============================= Ami Levi amil at kswaves.com Embedded platform engineer K.S.Waves Ltd.
