Lattice diamond 编译XO3的MIPI工程时报错” Cannot place PIO … because the types of their IOLOGICs are incompatible”, 怎么解决？
请问这个错误怎么解决？我想把MIPI RX模块的D2放到E6引脚上，却始终报错：
ERROR – Cannot place PIO comp “D2” on the proposed PIO site “PL5A / E6” because the types of their IOLOGICs are incompatible: the associated IOLOGIC comp “D2_MGIOL” has been set to “IDDR4” mode (of type “BIOLOGIC”), while the IOLOGIC site is of type “IOLOGIC”.
MIPI的数据lane，高速通道需要使用IDDRx4的资源，IDDR资源只存在于XO3的bottom BANK上存在，BOTTOM BANK是以PBxA/PBxB开头的，而你这个E6是是PL5A，也就是Left bank，这个BNAK是没有IDDR，因此报错，换成PBxA开头的引脚就可以了。
