Update: New network driver Odroid H2+ for CentOS 7.9 (r8125 LAN)

Update: I found the problem with the “buggy” network driver. It was actually the RAM which is behaving unstable. The RAM is Kingston HyperX Impact 8GB 2933MHz DDR4 CL17 – avoid it for the Odroid H2+. So both drivers should be stable enough.

Update 09.01.2021: I’ve built the driver for base 7.9 kernel  so you can install it from a flash drive, without a usb lan card. See the downloads section below.

Well the 9.003.05-1 version I found on ElRepo turned out to be buggy and killed my whole network. I downloaded the version r8125-9.004.01 driver from Realtek and applied the changes from the ELRepo patch. I made a new patch, so if you are interested in compiling the original source you can do this:

tar jxf r8125-9.004.01.tar.bz2
cd r8125-9.004.01
patch -p1 <../NickSoft-r8125-9.004.01-centos.patch
make --quiet
make install

Or you can get the rpms and rebuild from src rpm:

Make sure you update first. your kernel version needs to be higher than 3.10.0-1160.11.1.el7:
yum update

rpmbuild --rebuild --define "kversion $(uname -r)" r8125-kmod-9.004.01-1.el7.src.rpm

Then install the rpm:

rpm -Uvh /root/rpmbuild/RPMS/x86_64/kmod-r8125-9.004.01-1.el7.x86_64.rpm
