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.
Trying the recent mainline U-Boot (a6f0c4faa4c65a7b7048b) on an ARM2 board we get [1] after manually setting an ethaddr and the IP addresses.
Sometimes U-Boot seems to hang after 'MMC: FSL_SDHC: 0, FSL_SDHC: 1' but this might be an other issue.
Best regards
Dirk
