你是要用U盘刷机吗？最近的镜像是IMG文件，只能使用USB接口连接电脑，通过etcher刷机。

@jugg 现在可以支持在coolpi机器上直接编译uboot。

日期也不对啊

基于coolpi 4b ubuntu22系统编译coolpi nano（RV1106）内核

首先需要安装32位arm-gcc编译工具链

coolpi@coolpi:~/kernel/coolpi-kernel$ sudo apt install gcc-arm-linux-gnueabi Reading package lists... Done Building dependency tree... Done Reading state information... Done The following packages were automatically installed and are no longer required: aapt adb android-libaapt android-libadb android-libandroidfw android-libbacktrace android-libbase android-libboringssl android-libcrypto-utils android-libcutils android-liblog android-libunwind android-libutils android-libziparchive android-sdk-platform-tools-common fonts-lyx inotify-tools libboost-dev libboost1.74-dev libexpat1-dev libinotifytools0 libjs-jquery-ui liblbfgsb0 libllvm15 libopenblas-dev libopenblas-pthread-dev libopenblas0 libpython3-dev libpython3.10-dev libqhull-r8.0 libxsimd-dev python-matplotlib-data python3-appdirs python3-beniget python3-cycler python3-decorator python3-dev python3-fonttools python3-fs python3-gast python3-kiwisolver python3-lz4 python3-matplotlib python3-mpmath python3-numpy python3-packaging python3-ply python3-pyqt5 python3-pyqt5.sip python3-pythran python3-scipy python3-sympy python3-ufolib2 python3-unicodedata2 python3-wheel python3.10-dev unicode-data zlib1g-dev Use 'sudo apt autoremove' to remove them. The following additional packages will be installed: binutils-arm-linux-gnueabi cpp-11-arm-linux-gnueabi cpp-arm-linux-gnueabi gcc-11-arm-linux-gnueabi gcc-11-arm-linux-gnueabi-base gcc-11-cross-base gcc-12-cross-base libasan6-armel-cross libatomic1-armel-cross libc6-armel-cross libc6-dev-armel-cross libgcc-11-dev-armel-cross libgcc-s1-armel-cross libgomp1-armel-cross libstdc++6-armel-cross libubsan1-armel-cross linux-libc-dev-armel-cross Suggested packages: binutils-doc gcc-11-locales cpp-doc gcc-11-doc autoconf automake libtool gdb-arm-linux-gnueabi gcc-doc The following NEW packages will be installed: binutils-arm-linux-gnueabi cpp-11-arm-linux-gnueabi cpp-arm-linux-gnueabi gcc-11-arm-linux-gnueabi gcc-11-arm-linux-gnueabi-base gcc-11-cross-base gcc-12-cross-base gcc-arm-linux-gnueabi libasan6-armel-cross libatomic1-armel-cross libc6-armel-cross libc6-dev-armel-cross libgcc-11-dev-armel-cross libgcc-s1-armel-cross libgomp1-armel-cross libstdc++6-armel-cross libubsan1-armel-cross linux-libc-dev-armel-cross 0 upgraded, 18 newly installed, 0 to remove and 42 not upgraded. Need to get 37.7 MB of archives. After this operation, 119 MB of additional disk space will be used. Do you want to continue? [Y/n] ...

然后修改默认编译脚本

coolpi@coolpi:~/kernel/coolpi-kernel$ git diff build-kernel.sh diff --git a/build-kernel.sh b/build-kernel.sh index 3eb4d07d8041..4bb6d806ebd8 100755 --- a/build-kernel.sh +++ b/build-kernel.sh @@ -69,6 +69,9 @@ if [ "$RV1106" == "1" ]; then TOOLCHAIN_ARM32=$K_SRC/toolchain32uc/bin export PATH=$TOOLCHAIN_ARM32:$PATH fi + if [ "$ARCH" == "aarch64" ]; then + export CROSS_COMPILE=arm-linux-gnueabi- + fi coolpi@coolpi:~/kernel/coolpi-kernel$

执行nano主板内核编译

coolpi@coolpi:~/kernel/coolpi-kernel$ ./build-kernel.sh cpnano

编译生成目录结构

coolpi@coolpi:~/kernel/coolpi-kernel$ tree out out ├── extlinux │   └── extlinux.conf ├── initrd32.img ├── modules.tar.gz ├── rv1106-cpnano.dtb └── vmlinuz 1 directory, 5 files

更新Ubuntu22镜像文件，仅针对RKDevTool工具使用

已知bug：

挂载U盘、TF卡无权限 sudo chown coolpi:coolpi /media/coolpi sudo reboot

这是用V4L2-TEST打开时demsg打印的

测试两款SSD硬盘盒，启动镜像运行正常

Can you provide an android 12 image with wifi support?
