[U-Boot] Ethernet not functional on i.MX6DL Sabre Auto
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? https://pastebin.com/VnEdBCa6

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

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 !
