Hi, I need to support 2GB of memory on a custom 440SPe board.
I see to support 1GB of memory on the 440SPe yucca board the following configuration changes were done. # # Advanced setup # CONFIG_ADVANCED_OPTIONS=y CONFIG_HIGHMEM_START=0xfe000000 CONFIG_LOWMEM_SIZE_BOOL=y CONFIG_LOWMEM_SIZE=0x40000000 CONFIG_KERNEL_START_BOOL=y CONFIG_KERNEL_START=0xa0000000 # CONFIG_TASK_SIZE_BOOL is not set CONFIG_TASK_SIZE=0x80000000 # CONFIG_CONSISTENT_START_BOOL is not set CONFIG_CONSISTENT_START=0xff100000 # CONFIG_CONSISTENT_SIZE_BOOL is not set CONFIG_CONSISTENT_SIZE=0x00200000 # CONFIG_BOOT_LOAD_BOOL is not set CONFIG_BOOT_LOAD=0x01000000 It looks like the only thing I would need to do is modify the following for 2GB support. CONFIG_LOWMEM_SIZE=0x80000000 and CONFIG_KERNEL_START=0x60000000 But this does not work. It almost does, but right after I get to the Linux prompt, this system panics. If I scale back to one 1GB everything works great. Any ideas?
