Hi list, We have a requirement to use a bigger RAM (1 GB / 2GB) with a RM9000 based SOC. I thought of going with HIGHMEM path rather than enabling 64bit support thinking it will be easier. I have tried enabling HIGMEM in kernel. Board boots fine with a 512 MB RAM plugged in. But if I connect a 1 GB RAM kernel will not boot. I am not even getting single print from kernel. I am using linux-2.6.18 kernel. It will be great if get any pointers suggestions in debugging this? Thanks Anoop |
