I test tw6869 on i.mx6 , it work well with 6 D1 channel at the same time.
but it will encounter FIFO overflow warning while open 7 or 8 D1 channel.
It also work well with 8 channel while scale some channel with half size.
I also check message from:
It's seem that no one could enable 8 D1 channel at the same time.
I suppose that is i.mx6 PCIE bandwidth issue.
I estimate the bandwidth only 128M Byte instead of 500M PCIE 2.0 standerd
How to enable 8 channel D1 on i.mx6?
