Hi,
Did anybody get 512MB DDR SDRAM working on MPC8313?
My board here didn't work. In u-boot source, I changed CFG_DDRCONFIG to handle the 512MB ICs, changed CFG_IBAT_0U and CFG_DBAT_0U to handle 512MB, defined CONFIG_VERY_LAGE_RAM and CONFIG_MAX_MEM_MAPPED. When I set the CFG_DDR_SIZE to 256 to use only half memory, u-boot and Linux kernel (2.6.23) worked fine on this board. When I change CFG_DDR_SIZE to 512 to use all the memory, u-boot seems happy without error reporting, but crashed when booting the kernel.
Any help is highly appreciated.
Following is the boot log:
