To do that, pick DDR3 chips from a reputable manufacturer that comply to the supported memory organizations in the CPUs Reference Manual. U-Boot sources and AN3532 can be helpful for bringup.</P></BODY></HTML> Mon, 27 Apr 2015 06:30:22 GMT https://community.nxp.com/t5/P-Series/P3041-DDR3/m-p/445958#M2598 hwrobel 2015-04-27T06:30:22Z Re: P3041 DDR3 https://community.nxp.com/t5/P-Series/P3041-DDR3/m-p/445959#M2599 <HTML><HEAD></HEAD><BODY><P>Ok So the 5 chip configuration and 4 chip configuration as in cases(1) and (2) respectively are feasible ?</P></BODY></HTML> Mon, 27 Apr 2015 07:57:51 GMT https://community.nxp.com/t5/P-Series/P3041-DDR3/m-p/445959#M2599 hammadnayeem 2015-04-27T07:57:51Z
