Mbed-os: Nucleo F429ZI LWIP6 cannot get IP (Mbed OS 5.6.1) (Connect fails)

[teetak01]

Description

• Type: Bug
• Priority: Blocker

Bug

Target
NUCLEO_F429ZI + LWIP6

Toolchain:
GCC_ARM

mbed-os version:
5.6.0/5.6.1

Expected behavior
Device gets IP

Actual behavior
Device never gets IP

[EasyConnect] MAC address 00:80:e1:2c:00:28
[EasyConnect] Connection to Network Failed -3010!
MainThread: Test Case fails because of: Failed to initialize connection

Issues in Mbed OS 5.6.0 are intermitted. Sometimes the Connect fails, with Mbed OS 5.6.1 this seems to happen always.

Wifi IPv4 work

[0xc0170]

I am looking at changeset for 5.6.1 - https://github.com/ARMmbed/mbed-os/pull/5184 (I can not spot there changes to this target neither lwip). I suspect 5.6.0 also have this problem, then we need to bisect more files to actually get the change that caused this

@adustm Can you help?

[mikaleppanen]

I cannot reproduce this with our ipv6 connection (4g router) and F429ZI. Both example client and client testapp works ok with ipv6 ethernet.

[JanneKiiskila]

Indeed, @mikaleppanen is right - turns out we had a really strange CI networking issue - some boards didn't get an IP-address anymore, while some boards in the same setup did. We've never seen this kind of failure before and as some other boards were getting both IPv4 and IPv6 address we never guessed to suspect a network issue. But, that was the root cause for this incident.

Apologies for the false alarm. This issue can be closed (only I can't do it). @0xc0170 or @adbridge - can you please close this issue?

[teetak01]

Yeah, turned out be a test-lab issue. Closing. Nucleo is working again for us.
