I could see one issue with U-Boot/Linux binaries I had run on my IMX6UL-EVK board
that came from L4.1.15_1.1.0_ga_images_MX6ULEVK.tar.gz
U-Boot 2015.04-imx_v2015.04_4.1.15_1.0.0_ga+gd7d7c43 (Apr 01 2016 - 10:17:30)
Linux version 4.1.15-1.1.0+ga4d2a08 (bamboo@shlinux12) (gcc version 5.2.0 (GCC) ) #1 SMP PREEMPT Fri Apr 1 05:37:10 CST 2016
At Power ON "eth1' interface always starts without problems.
But If I execute a 'reboot' command then 'eth1' does not start permanently.
fec 2188000.ethernet eth1: Freescale FEC PHY driver [Generic PHY] (mii_bus:phy_addr=20b4000.ethernet:02, irq=-1)
IPv6: ADDRCONF(NETDEV_UP): eth1: link is not ready
'ifconfig -a' shows
eth1 Link encap:Ethernet HWaddr 00:04:9F:04:20:01
BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)
I have tried to connect 'eth1' of my board to 3 different routers and switches.
The results are the same and negative. The 'eth1' link does not become ready.
With kernels Linux 4.6 and 4.6.3 I have not seen that issue.
Any help would be appreciated
Thanks in advance
