I get : U-Boot 1.3.2-00075-gc5f497a-dirty (Mar 25 2008 - 19:55:00) MPC83XX Reset Status: Check Stop, External/Internal Soft, External/Internal Hard CPU: e300c1, MPC8343, Rev: 31 at 399.999 MHz, CSB: 266 MHz Board: Matrix Vision mvBlueLYNX-M7 I2C: ready SPI: ready DRAM: cs0_bnds = 0x0000000f cs0_config = 0x80844102 DDR:bar=0x00000000 DDR:ar=0x8000001b 256 MB It's a 32-Bit DDR-II without ECC. 2 Chips are soldered to CS0, i.e. no EPROM present. Since I expect something like "(DDR2, 32-Bit, ECC off)" and nothing happens there is obviously something wrong with my memory setup. Is this reasonable ? Or am I simply missing a board specific "board_add_ram_info" ? Am I assuming right that your info string "(DDR2, 64-bit, ECC on)" comes from spd_sdram ? >> Are there any patches not yet posted to handle this ? >> >> > should work, only diff I see is that the 8343 is 32-bit only. > > Kim > I'll dig a little deeper now and ask more questions tommorow.
