Hi, I have an MPC8360-RDK board that has 512MB of DDR2 RAM.
I updated the MPC8360ERDK.h file from the latest archive ( 2009.03-rc2) to add support for the 512MB of RAM. (from the default 256MB). Basically, I just did the following: changed CFG_DDR_SIZE from 256 to 512 changed CFG_DDR_CS0_BNDS from 0x0000000f to 0x0000001f made CFG_IBAT6L and CFG_IBAT6U match IBAT0L and IBAT0U, respectively (except, I changed the BEPI and BRPN fields to be 0x1000 since the upper 256MB of my RAM should begin at 0x10000000) set CFG_DBAT6L and CFG_DBAT6U equal to CFG_IBAT6L and CFG_IBAT6U, respectively. make with MPC8360ERDK_33_config then build the U-Boot binary Lastly, I've verified, using the RAM data sheet, that the other configuration parameters for the RAM should be identical to the default values (e.g., row=13, col=10, and timing configurations). Does anyone have any idea why this doesn't work? It seems like a pretty trivial update, but it causes U-Boot to hang up at the "DRAM:" line (see below). Thanks Christopher M.
