NEO u-boot: no ethernet found

Hi,

I want to netboot my udoo-neo but when trying I get:
Net: CPU Net Initialization Failed
No ethernet found.

Am I the only one having this?
Is this a known problem?

 

Dear Luc,
sorry, we haven't tested netboot yet. Is there some information we can give you to help you test it?

 

Hi Andrea,

I'm not sure
I've seen that the network options are not defined in include/configs/udoo_neo.h
But even after having enabled them, recompiled the u-boot image and installed it on a SD card
it still not working, giving the following message on the console:
Net: Phy not found
PHY reset timed out
FEC0

A ping take a long time (10 seconds) and then fail:
=> env set ipaddr 192.168.1.31
=> ping 192.168.1.1
Using FEC0 device
ping failed; host 192.168.1.1 is not alive

So yes, I would guess that there is something with the PHY (is it the same as the dual or quad?)

Hi there Luc,
no, it's not the same. The code of PHY is different.
The PHY's code of Neo is KSZ8091RNAIA
Sorry if I don't have so much information, but I'm not practical on this. For every information you need do not hesitate to ask.
I don't know if this is the same PHY used on i.MX 6 SoloX Sabreboard.
However, here is Neo's schematics, I think you were looking for them.

 

Hi,

I solved this issue.
Attached file is patch set for commit d781468.
(https://github.com/UDOOboard/uboot-imx/commit/d7814685bdb364a4162f5bb4431676631591fc38)

 

Are you telling us that now netboot works fine?

 

Yes, netboot(tftpboot and nfs) works fine on my UDOO Neo Full.
See attached log files.

 

Great man! We will add support in the uboot after testing it
