I used the pins shown in the the IMX6Q datasheet and the I/O Mux tool to define the pins. I just saw a table on page 3795 of the reference manual that talks about DRAM muxing for LPDDR2 pins being different than what is called out in the datasheet and I/O mux tool...........is this for real? Is there any way to get my board to work (other than hardware fixes) ?</P><P></P><P>Thanks,</P><P>Kevin</P></BODY></HTML> Thu, 15 Aug 2013 12:23:42 GMT https://community.nxp.com/t5/i-MX-Processors/DRAM-mux-mapping-to-LPDDR2/m-p/256937#M24786 kbell_hardware 2013-08-15T12:23:42Z Re: DRAM mux mapping to LPDDR2 https://community.nxp.com/t5/i-MX-Processors/DRAM-mux-mapping-to-LPDDR2/m-p/256938#M24787 <HTML><HEAD></HEAD><BODY><P>Sorry that the DDR3 and LPDDR2 pin mapping are different, and it can't be swap by SW setting.
