documentation:

avoid issue with USB3 SSD storage adapter

Well linux supported adapter chipset: JMicron JMS578 (SATA 6Gb/s USB3.0) 152d:0578

doc:

for ARMbian, blacklist UAS storage driver for this USB adapter:

  • edit /boot/armbianEnv.txt (used indirectly by /boot/boot.cmd)

  • append ,174c:55aa:u at the end of usbstoragequirks=... (not __0x0__714c etc...)

  • reboot

  • check it worked: sudo dmesg | grep "UAS"

    should return: usb 4-1: UAS is ignored for this device, using usb-storage instead

build openWrt from git

/!\ don't cross-compile on an encrypted mount point (eg. /home/nouknouk on noukfractal). Otherwise, you'll get cryptic error like "uglic++ compilation failed"

install build dependencies

sudo apt update
sudo apt install build-essential ccache ecj fastjar file g++ gawk gettext git java-propose-classpath libelf-dev libncurses5-dev libncursesw5-dev libssl-dev python python2.7-dev python3 unzip wget python3-distutils python3-setuptools rsync subversion swig time xsltproc zlib1g-dev

some custom additions (for wireguard, docker packages ?) sudo apt install libjson-c-dev python3.9

download sources

work in progress nanopi-r4s fork
git clone https://github.com/1715173329/openwrt-official.git
cd openwrt-official
git checkout nanopi-r4s

Specific for free ISP en ZMD:

  • you may want to change directly file package/network/ipv6/map/files/map.sh
  • you may want to inject package/base-files/files/etc/init.d/promiscuous in image
alternatively, for 'main branch:
git clone https://git.openwrt.org/openwrt/openwrt.git
cd openwrt
get feeds (= download 3rd party software)
./scripts/feeds update -a
./scripts/feeds install -a

configure

save/restore a custom config

  • save current config:

    ./scripts/diffconfig.sh > saved.config

  • restore config & merge with defaults:

    cp saved.config .config
make defconfig
configure

  • make menuconfig and set target.

    • target Rockchip, subtarget RK33XX, profile FriendlyARM NanoPi R4S
    • Use r8168-8.048.03 realtek kernel module(much better than r8169)

  • download custom eth1 (LAN) driver r8168 to replace r8169

    git clone https://github.com/BROBIRD/openwrt-r8168.git
# from openwrt repo folder:
cp ../openwrt-r8168 ./package/kernel/ -R
rm -Rf ./package/kernel/openwrt-r816/.git

  • make defconfig to set default config for build system and device.

  • make menuconfig again and modify set of package (install = *)

    • for opkg download compatibility:
      • select: Advanced configuration options
      • select: Global build settings → Select all kernel module packages by default
      • __de__select: Global build settings → Kernel build options → Compile the kernel with symbol table information
      • fill builder: Global build settings → Kernel build options → Custom Kernel Build User Name
      • fill buildhost: Global build settings → Kernel build options → Custom Kernel Build Domain Name
    • Network: add packet map (for Free 4rd)

  • scripts/diffconfig.sh > mydiffconfig (save your changes in the text file mydiffconfig).

build

build with explicitely specifying first the download action, to avoid simple make fail when multi-core option is set.

if build fails, re-run make without multi-core options (aka -j 1)

make -j13 download && make -j13 world

After build, output images can be found in subdirectory bin/targets/rockchip/armv8/

build errors

ERROR: package/libs/gettext-full [host] failed to build.
ERROR: package/feeds/packages/samba4 [host] failed to build.
  • Network/samba4-utils, ... makes compilation fail ; remove it.

write on SD card.

gunzip and write on SD card the SQUASHFS generated image: ./bin/targets/rockchip/armv8/openwrt-rockchip-armv8-friendlyarm_nanopi-r4s-squashfs-sysupgrade.img

4rd traffic mapping

For 4rd (=encapsulation of IPv4 traffic into IPv6 packets):

  • install the package map (better: include in compiled image)

    edit /lib/netifd/proto/map.sh

echo "$RULE_DATA" >> /tmp/map-$cfg.rules
eval $RULE_DATA
