download from sourceforge kernel source and dsm toolchain (my ds218 has rtd129x)
- https://sourceforge.net/projects/dsgpl/files/Synology%20NAS%20GPL%20Source/22259branch/rtd1296-source/
- https://sourceforge.net/projects/dsgpl/files/DSM%206.2.2%20Tool%20Chains/Realtek%20RTD129x%20Linux%204.4.59/
from a brand new debian system: create a folder:
sudo apt update
sudo apt install wget
mkdir -p ~/dsm/archives
cd ~/dsm
put:
- rtd1296-gcc494_glibc220_armv8-GPL.txz
- linux-4.4.x.txz
install all build deps:
sudo apt-get install mc make gcc build-essential kernel-wedge libncurses5 libncurses5-dev libelf-dev binutils-dev kexec-tools makedumpfile fakeroot lzma bc libssl-dev
extract and move txz archives away:
tar Jxvf linux-4.4.x.txz
tar Jxvf rtd1296-gcc494_glibc220_armv8-GPL.txz
mv linux-4.4.x.txz rtd1296-gcc494_glibc220_armv8-GPL.txz archives/
enter in kernel source folder and copy kernel config in place
cd linux-4.4.x/
cp synoconfigs/rtd1296 .config
export magic number version (if not exported could cause headaches!) and alias for dsm make
export LOCALVERSION=+1
alias dsm6make='make ARCH=arm64 CROSS_COMPILE=~/dsm/aarch64-unknown-linux-gnueabi/bin/aarch64-unknown-linux-gnueabi-'
config the kernel, select all modules for iptables and make modules:
dsm6make menuconfig
dsm6make modules
find . -iname "*.ko" -type f
copy the kernel modules in /lib/modules on synology machine. DO NOT OVERWRITE already present modules.
use insmod command to load.
for troubleshooting check dmesg for errors.
