Trying to get BCM57780 to work

Installing and Using OpenWrt
1

I have searched a lot, installed drivers like the kmod tg3 and a few others, rebooted, still doesnt work. What can I try to fix it? It does get recognized if I boot into finnix.

2

I think it is bnx2 and needs some firmware
Check ethtool -i eno1 for driver and sweep dmesg for firmware files.

3

i cant find the ethtool, and bnx2 is already installed, so i dont understand whats wrong..

4

From a desktop linux distribution run lspci -nnv and ethtool -i eno1 to identify device and used driver.

5

lspci says kernel driver in use: tg3
kernel modules: tg3
name says Ethernet controller Broadcom Limited Netlink BCM57780 Gigabit Ethernet PCIe rev 01
ethtool going to check in a sec

6

ethtool says
driver: tg3
version: 3.137
firmware version: sb
what now?

7

pci numbers to check if it is supported in 23.05 or you need snapshot?

8

you mean the enp2s0? or...

9

you mean [14e4:1692]?

Cool, it is supported by kmod-tg3. Is it requesting and not getting firmware when openwrt is booting? In OpenWRT equipped with kmod-tg3 dmesg | grep -i tigon

One of these:

firmware:       tigon/tg3_tso5.bin
firmware:       tigon/tg3_tso.bin
firmware:       tigon/tg357766.bin
firmware:       tigon/tg3.bin

???

I booted up openwrt, ran the command after it booted up but it didnt give me anything.

Add module to your image when using firmware-selector.openwrt.org

still doesnt work, the dmesg still doesnt return anything, i check which kmod-tg3 is installed and it says 5.15.167-1

15

You have to get more specific than that.

16

The ethernet still doesnt get detected if i use ifconfig, and the dmesg still doesnt work, what is there left to try?

Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button:
