DRAM mux mapping to LPDDR2

[kbell_hardware]

All,

I am having trouble getting the LPDDR2 SDRAM on my iMX6Q board to function. 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) ?

Thanks,

Kevin

Sorry that the DDR3 and LPDDR2 pin mapping are different, and it can't be swap by SW setting. So fix it by HW modify is the only way.
