Hi , we want to test USB eye diagram on iMX8M
But we don't know how to test , we have already seen this link i.MX6Q/eye pattern of USB HS1 setup
We have tried the register (DCTL)
＃./memtool -32 0x3810c704=0x00F00008
but it's not work for us and evk board.
We want to force to output Test Packet , how to do this ?
