imx27ads redboot mxc_fec

[zbsar]

Using redboot I set the default network device to mxc_fec. This ends up in an error when loading the image: load -r -b ... returns a network error.

Now, if I use the cs8900a_eth0, then the kernel nfs boots, and the FEC can be configured.

So here is my question:

Can we use the FEC interface from Redboot. Is this a Redboot bug? or am I doing something wrong.

Hi zbsar,

What revision # of ADS do You use?

In old version of the i.MX27ADS there was a problem with FEC:

FEC didn’t work. It caused by the wrong direction control in the buffer (U69).

It fixed by the board rework

 Hello Wagan,

I am not sure how to check the version because I don't have physical access to the board.
Here is what I have, Let me know if there is anything to check. The issue is that after booting over the cs8900_eth0, I can configure the FEC using ifconfig and access the system on that interface.

Thanks,
zbsar
