LicheeSG-Nano-Build

• updated build, fsbl, opensbi, u-boot, linux, middleware (cvi_mpi and SensorSupportList) and osdrv to sophgo weekly rls 2024.10.14
• updated isp_tuning to sophgo weekly rls 2024.09.11
• updated freertos to sophgo weekly rls 2024.06.6 and ramdisk to sophgo weekly rls 2024.07.20
• merged mainline v5.10.235 into linux_5.10
• updated buildroot to 2025.02
• added maix_mmf sources and media_server submodule to middleware/sample/test_mmf
• imported rtsp_server from maixcdk to middleware/sample/test_mmf
• added support for nanokvm
• minimal fixes for a53 build
• Kept backward comptabibility for older middleware used by MaixCDK and NanoKVM app
• added build of NanoKVM server and web from source
• added flag to NanoKVM server to force download of libmaixcam_lib.so on first login
• added flag to NanoKVM server to disable tailscale
• imported maix_err, maix_fs and maix_log from MaixCDK and added functions to maix_mmf sources to build libmaixcam_lib.so replacement in middleware/sample/test_mmf
• added h264, vdec, maix_avc2flv and other functions to libmaixcam_lib.so
• created kvm_system replacement in middleware/sample/kvm_system as NanoKVM Full OLED controller
• created kvm_stream replacement in middleware/sample/kvm_stream for NanoKVM 2.0.9 and earlier
• created kvm_vision libkvm.so replacement in middleware/sample/test_mmf for NanoKVM 2.1.0 and later
• replaced download of NanoKVM latest.zip with nanokvm-skeleton git repo containing only non-binary files
• created dummy libs for ae, af, awb, cvi_json-c, cvi_miniz and isp_algo in middleware/modules/dummy to avoid usage of any pre-built closed source lib
• created light libs for cvi_bin, cvi_bin_isp and isp in middleware/modules/isp_light to reduce usage of dummy code
• dummy and light libs are currently only used in kvmapp folder for NanoKVM, the real libs are still required and used for the other projects with camera module
• added build of tailscale from source
• synced defconfig and dts from licheervnano to licheea53nano
• updated build scripts to compile the firmware (including MaixCDK and NanoKVM) for a53 mode (ARM 32-bit and 64-bit)
• added submodules to compile tpu sdk
• added compatibility for generic gnu toolchain (gcc/glibc) on all components (except tpu)
• created cvi_json-c and cvi_miniz open source replacement in middleware/modules/bin
• replaced host-tools by reproducible toolchain https://github.com/scpcom/riscv-gnu-toolchain/releases/tag/riscv64-gcc-thead_20230307-10.2.0-x86_64

download source

git clone https://github.com/scpcom/LicheeSG-Nano-Build --depth=1
cd LicheeSG-Nano-Build
git submodule update --init --recursive --depth=1

You can remove the --depth=1 parameter to get full history.

host environment

• OS: Debian 11/Ubuntu 22.04 or higher is recommended
• CPU: AMD/Intel x86_64 (for ARM aarch64 and others ./host/replace-all-thead-toolchains.sh maybe used)
• Memory: 8 GB RAM (Required to build opencv tests, all other can be complied with 4GB and below)
• Storage: 30GB free space minimum (plus optional 40GB to compile the toolchain)

On Debian/Ubuntu you can install required packages with:

./host/prepare-host.sh

Or you can use container:

docker build -t builder -f host/Dockerfile .
docker run --privileged -it --rm -v `pwd`/image:/output builder sh -e -c "BOARD_SHORT=licheervnano ./make_image.sh"

build it

./build-licheervnano.sh

build nanokvm

./build-nanokvm.sh

build fail

on some systems, qt5svg or qt5base will fail on first build, please re-run the build command.

how to modify image after build:

# first partition
touch wifi.sta
mcopy -i install/xxx/xxx.img@@1s wifi.sta ::/

# second partition
./host/mount_ext4.sh install/xxx/xxx.img mountpoint
cd mountpoint
touch xxx

logo

./host/make_logo.sh input.jpeg logo.jpeg
mcopy -i install/xxx/xxx.img@@1s logo.jpeg ::/
