Hi, I am using a i.MX27 connected to a LPDDR from Micron (se link). I need to lower the drive strength of the memory to half as described at the memory datasheet on page 55 Extended Mode Register ( http://download.micron.com/pdf/datasheets/dram/mobile/512mb_ddr_mobile_sdram_t47m.pdf )
In U-Boot in lowlevel_init.S (/board/logicpd/imx27lite/) there is a line #define SDRAM_MODE_REGISTER_VAL 0x100000 Which I assume is the value written to the Extended Mode Register. Honestly I really do not know what value I should change the 0x100000 to. Some how I would like to think it would be 0x1000020 but I really could not say that is correct. Do any of you have any idea I would be very grateful. Kind Regards Martin Sjölund
