TMDSSK3358_3H0009_REV1_2B_SCH 使用的是DDR3 MT41J128M16JT-125 , 下方的 DQ訊號是交錯對接 ( AM335X DDR_D3 接到 DDR3 的 DQ0 ) 如果是使用EM6HE16EWAKG DDR3L 的規格, 是否允許這樣swap ? 謝謝.

Can we swap the DDR3 DQ pins on the processor (P1015) side with in the byte lane, in any random fashion. Like Before After (Swapping)
ca_swap:DDR CA线序参数,如下图: 则ca_swap参数应配置为0x00503412。 dqs_swap: DQ byte-lane信号组线序参数,配置原则跟CA一样,只是该参数以8位数据线位一组,反映H3/M3的32根DQ线(4组)与DDR端的组对应关系。 dq_swap:DQ信号组内线序参数,该组4个参数分别表示4组DQ线的组内对应关系。 3、修改board...
