Hi Jason,
I don't have a mx6qarm2 and would like to ask you if you could please confirm that Ethernet is functional on mx6qarm2 running the latest U-boot.
I am trying to get Ethernet working on mx6qsabresd, which also uses the same AR8031 PHY, but it is not working yet.
AR8031 is supposed to output a 125MHz clock to mx6q, but I see a 25MHz clock instead.
I do the same PHY init as in mx6qarm2.
Any ideas/suggestions are appreciated.
I think a coworker has an ARM2, so I'll try to ask him on Monday.
But while talking about ethernet on MX6: There seems to be a lot of issues with 1GB ethernet. Or is it just confusion? As I'm no expert on this, I'm really confused. That means that I don't know if we still really have some issues with it or not :(
The initial SabreLite boards (revision from September/Octorber last year?) had a hardware issue with 1GB ethernet. I was told that this hardware issue is fixed in the latest SabreLite boards with hardware revision D. But a coworker reports that it looks like GB ethernet even doesn't work with the U-Boot the SabreLite revision D ships with (?). Nor a more recent (patched?) U-Boot. I'm not sure if the recent (unpatched) mainline was tested, though. So this might be an issue of an U-Boot version which has SW patches for the old, broken ethernet applied, which now breaks the fixed hardware? Or is there still an hardware issue? I don't know.
In parallel, there is some rumor that on a Freescale board (SabreAuto? Have to check on Monday) 1GB doesn't work, too.
As mentioned, this are all reports I got, I haven't done any testing myself. If anybody could clarify on this, this would be nice.
Many thanks and best regards
Dirk
