@jack_admin said in how about batocera with cool pi 4b:

Test firmware link

@Macs have you test version 36?

@大法师
刷的这个

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

nice board for server!

@大法师 26T大概是什么水平？

@大法师 更新内核ap+sta后貌似正常 。
新的问题出现 运行过程中提示
global cap_v4l.cpp:1119 tryIoctl VIDEOIO(V4L2:/dev/video0): select() timeout.
Exception in thread Thread-4:

Erase partitions

Tf card:
sudo wipefs -a -f /dev/mmcblk1

EMMC:
sudo wipefs -a -f /dev/mmcblk0

可以先用buildroot版本镜像验证CSI摄像头，Ubuntu与其他发行版本还在优化适配中。

这是软PWM，需要重写封装WiringPi

@retroman Hey! Do you mean of the Amazon cards? I've actually found that the 128GB model I have is slightly slower in most areas than the 64GB cards, so it's the 64GB one I recommend in most cases!

I wouldn't be able to say where the difference is exactly, I use the same microSD card on the board and they're all just blank cards with an ext4 filesystem on them tested in exactly the same way. I'd have perhaps expected both of them to be closer than they are but in the boards I've tested with the 128 so far (I only picked it up over Christmas) it's been consistently slower than the 64 but still very good overall.

@retroman Thank you for your suggestion. We will discuss the time point of support internally.

Can you provide an android 12 image with wifi support?

机器没有识别到这个HDMI设备。可能是接口或者分辨率非标准导致。
