RC can not write data to i.MX6SX(EP) again

Frankly speaking, when we put i.MX6SX into EP mode, we find that RC can only write the data to i.MX just one time. The procedure is, firstly i.MX is configured the bar size(bar 0/1 64bit 8M), then RC will pcie scan all the devices including i.MX, finally i.MX will do the BAR0/1 inbound mapping using BAR matching, and i.MX doesn't work well in inbound address matching mode.


We find RC can succeed to write the data to i.MX, but fail to access to i.MX the other time, can anyone provide some help?
