Broadcom gigabit ethernet

Code: Select all

No PHY devices
Problem fetching invariants of chip, aborting

The onboard chip is the BCM57780
Is the tg3 module only one part of the driver, do I need broadcom firmware as well? Can't find any such package in the list

[NicePics13]

Booted a livecd where the nic is detected:

Code: Select all

# lsmod | grep tg3
tg3                   118116  0
ptp                     7270  1 tg3
libphy                 16372  2 tg3,broadcom
hwmon                   1865  1 tg3

So it seems a broadcom module is missing from gargoyle.

What gargoyle firmware version did you flash, and on what architecture/platform?
Thanks for checking the livecd, that helps!

[NicePics13]

1.12 and 1.13 x86 generic ext4 on this cheap thin client:

Ok great.
So it looks like it was not built with that Broadcom phy driver. Unfortunately there’s no way to safely install it, so you need to compile a new image with the required driver built in.
There are instructions on how to do so, are you comfortable trying?

[NicePics13]

Sure, it's been ages since I compiled my own kernel
Hopefully it won't take too long on my old Core 2 Quad

Generally I’d suggest a clean compile of the default image to ensure your build environment works correctly. After that is successful, go back in and add your customisation, then build again.

Got the 1.12 32-bit x86 build to compile in Debian, probably took 5-6 hrs
Edited the default profile in the targets directory but that stops with:

Code: Select all

Package kmod-phy-broadcom is missing dependencies for the following libraries:
bcm-phy-lib.ko

[Lantis]

Edited the default profile in the targets directory

How? If you did it by hand, you have to resolve dependencies manually as well.
https://git.openwrt.org/?p=openwrt/open ... 7251e#l247
Make sure that the 2x other dependencies are also selected.
They might have other downstream dependencies as well (I didn’t check).

[NicePics13]

My bad, forgot the deps.
