Hi All, When i use 128M in my board configuration and pass the same to he kernel using bd_info , the linux kernel just boots up fine. But when i change the config to put 256M which is the actual physical DDR size on our board, the userspace crashes because of a "unhandled page fault" via Unable to handle kernel NULL pointer dereference". First off, perhaps the U-boot is not initializing the memory properly. Although i thought, the board specific "dram_init" does it with the correct config params picked up from the board config file.
I change the following in the board specific config: #define CONFIG_NR_DRAM_BANKS 2 #define PHYS_SDRAM_1 CSD0_BASE #define PHYS_SDRAM_1_SIZE (256 * 1024 * 1024) What else does the uboot need to convey to the kernel. I am using Freescale MX31 board. Any hints/clues? Thanks in advance for your help. -Alfred. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
