C2 eth0 fails on some board

Recommended Posts

Hi all,

I have a problem with current DEV kernel. On some boards, everything works nicely, and after booting the kernel network is stable,

on some other C2 boards, I get error messages on the eth0 dwmac, and no network:

I tried with the same eMMC card on different boards.

Board who fail with DEV kernel work with NEXT kernel, this one I checked, so I assume we have a problem in DEV kernel with C2 dwmac.

 

Any ideas?

 

EDIT: seems only to affect rev0.2_2017114 boards. rev0.2_20160226 seems to work. Can anyone crosscheck this behaviour with a dev/buster image?

 

So far, Michael

Michael was asking me in a PM where the MAC address is persisted during "first boot" ...
[mention=4652]TonyMac32[/mention] are you aware of the persisted address file location ?

I'm afraid not. :-/
@mboehmer you say only the later board revision? Very odd.

[edit]

https://wiki.odroid.com/odroid-c2/hardware/hardware

 

 

EL-1709	rev0.2 20170830	The schematic is 100% identical to rev0.2 20160226. however, PCB manufacturers are different
and some signal patterns were reinforced and modifed to improve productivity.
EL-1801	rev0.2 20171114	Added a 0Ω between USB Hub IC and load switches.
To disable the USB over-current protection, you need to remove the 0Ω resistor.

I don't know what this would have to do with the eth0 interface.

It is very strange. Boards failing with dev kernel work with next kernel. The board rev is the only feature so far which seems to make a difference.

I will return for the time being to NEXT kernel, and add the necessary patches to device tree there.

The MAC issue I think can be solved. Apparently the /usr/bin/armbian/armbian_firstrun takes the (by uBoot correctly set) MAC address and uses nmcli to fix it in software (which seems pretty useless for me, as it is stored in efuse anyhow in each board).

Manually removing the "cloned-mac-address" line in NetworkManager config file (/etc/NetworkManager/system-connections/*) forces the eth0 to use the uBoot provided MAC again.

Edit: I think this line

# varios temporary hardware workarounds
[[ $LINUXFAMILY == meson64 ]] && set_fixed_mac

should be changed accordingly to not tinker with C2 MAC address anymore.

Update: compiled a new image (Armbian_19.11.9_Odroidc2_buster_current_5.4.16), and this one is working again on C2 rev 0.2 201171114 - eth0 is online.

uSD card also seems to work as expected.
