[U-Boot] Ethernet not functional on i.MX6DL Sabre Auto

[U-Boot] Ethernet not functional on i.MX6DL Sabre Auto

[Miquel RAYNAL]

Hi,

I am using a Sabre Auto board with an i.MX6 Dual Lite.

When I compile U-boot with defconfig file mx6dlsabreauto_defconfig, the
network is not functionnal. Only the orange LED on the RJ45 port is
blinking and dhcp requests never end. In menuconfig I saw numerous
unselected options that I guess should be enabled. But event with that,
I could not get through:

CONFIG_NET_RANDOM_ETHADDR=y
CONFIG_PHYLIB=y
CONFIG_NETDEVICES=y
CONFIG_FEC_MXC=y

The issue is present in v2017.05 and v2017.07 (did not tried previous
versions). Any idea of what could possibly be wrong ?

Boot log follows.

Thank you,
Miquèl

I don't have my mx6sabreauto handy to investigate this problem.

Does the change below make Ethernet to work again?

And here is a patch against u-boot-imx tree (
http://git.denx.de/?p=u-boot/u-boot-imx.git;a=summary)

No need to change anything in defconfig. Only do:

make mx6sabreauto_defconfig
make

and Ethernet should work with the patch applied.

Please let me know how your test goes.

Thank you for the very quick answer, I was not able to test the patch
yesterday but now I can confirm it works and Ethernet is functional
again on mx6sabreauto design.

The patch you sent does only apply on imx tree though (the path
contains mx6sabreauto instead of mx6qsabreauto).

Best regards,
Miquèl

Thanks for testing!

On the latest u-boot-imx tree the mx6sabreauto have been converted to
SPL, so the same SPL + u-boot.img can boot mx6q/mx6dl/mx6qp sabreauto
boards.

That's the reason we have renamed it from mx6qsabreauto to the more
generic mx6sabreauto naming.

Right - thanks for fix and testing. I have already merged it into
u-boot-imx, thanks !
