Setting up ETH ethernet on a custom carrier with TQMa6UL2-AA

89 views Asked by At

I'm setting up a custom carrier board made in my company with one TQMa6UL2-AA i.MX6UL based on evaluation board of TQ stka6ul. I already have a booteable image with u-boot and linux generated with Yocto-Project and TQ BSP. I'm traying to set-up the two ethernet interfaces,

In u-boot I could see the interfaces:

=> mii info
PHY 0x00: OUI = 0x01F0, Model = 0x0F, Rev = 0x01, 100baseT, FDX
PHY 0x01: OUI = 0x01F0, Model = 0x0F, Rev = 0x01, 100baseT, FDX

And, if I config the IP address, I could make a ping to one computer, so I think the hardware is working,however, in Linux I couldn't see nothing. I don't know how I could fix this problem, I suppose the Linux kernel can't recognize the PHY but I don't know why.

Could anyone help with my problem?

Regards,
