Build Linux Firmware

Download SDK

Please contact "sales@t-firefly.com" to get SDK download link .

Notice:


1. SDK use cross-compilation, so use SDK in x86_64 PC, do not download
SDK to the device


2. We suggest to use Ubuntu20.04 (real PC or docker) to build, other
OS may cause building failure


3. Do not place or decompress the SDK archive in Virtual Machine share
folder or non-english folder


4. Please use the regular user to get/compile the SDK, use root
privilege may cause building failure


Decompress SDK

   mkdir rk182x-developer-kit
   cat rk182x-developer-kit.tgz.split* | tar -xzv -C rk182x-developer-kit/


rk182x

   cd rk182x-developer-kit/rk182x
   .repo/repo/repo sync -l

rk3588

   cd rk182x-developer-kit/rk3588
   .repo/repo/repo sync -l

rootfs

Download rootfs, eg: Debian12-Xfce_rootfs_v1.2-55_20250825.7z

Decompress rootfs and create a symbolic link

   cd rk182x-developer-kit/rk3588
   mkdir prebuilt_rootfs
   cd prebuilt_rootfs
   7z x Debian12-Xfce_rootfs_v1.2-55_20250825.7z
   ln -sf Debian12-Xfce_rootfs_v1.2-55_20250825.img rk3588_debian_rootfs.img

Preparations

Run these two commands to install necessary tools

   sudo apt update

   sudo apt install repo git ssh make gcc libssl-dev liblz4-tool \
   expect g++ patchelf chrpath gawk texinfo chrpath diffstat binfmt-support \
   qemu-user-static live-build bison flex fakeroot cmake gcc-multilib g++-multilib \
   unzip device-tree-compiler ncurses-dev p7zip-full

RK3588

goto the dictionary of rk3588

Config

   ./build.sh firefly_rk3588_aio-gs1n2-3588jd4-rk182x_debian_defconfig

Build

   ./build.sh all

The generated firmware at "output/update/" , eg: "AIO-
GS1N2-3588JD4-RK182X_Debian12-Xfce-r1255_debug_251126.img"

RK182X

goto the dictionary of rk182x

Config

use "./build.sh config" to config.

   Select board type:
   1) RK1820 EVB1
   2) RK1820 SODIMM
   3) RK1820 M2
   4) Cancel
   #?

Select "2"

Build

   ./build.sh

The generated software installation package is located at
"output/firmware/rknn3_rk182x_sodimm_installer_arm64.tgz"

The rootfs used by RK3588 have already installed the necessary
software packages for rk182x

If you need to manually install the RK182X software package, follow
the steps below:  Copy rknn3_rk182x_sodimm_installer_arm64.tgz to
RK3588  Decompress: tar xzf rknn3_rk182x_sodimm_installer_arm64.tgz
Install: ./install.sh  After installation and rebooting, the RK3588
system will automatically download the RK182X firmware and start the
background service program upon startup.
