I use the imx6q+KSZ8041FTLIphy chip, according to the official reference design of the RMII interface network,But there is a phenomenon of network packet loss.

Constantly power off and power off to test the packet loss phenomenon. I found that if there is a packet loss at a certain power-on, if it is not powered, it will continue to lose packets. This phenomenon may disappear if the power is turned off. However, there are several boards, the phenomenon is more serious, it may be tested several times, this phenomenon will occur, but some boards are difficult to test this problem.

in the schematic,Y3 is not  populated!
