Hi, I have been working with Kernel development and single-board computers for a few years now, and to help me with my development, I created this tool: https://github.com/lucastanure/kernel_dev_tools (GPLv2) It helps me to build and test the kernel in a faster and easy way. But it also helps me to switch between boards (Rpi4, Vim4, Vim3, rk399) in a reliable way. The aim of this tool is to centralize the configuration of a particular board (cross-compiler, kernel configuration, make targets, etc.) in a config file and expose a simple workflow. Example: I have my VIM4 board configuration: [vim4_arm64] cc = aarch64-none-linux-gnu- cc_path = ~/.local/bin/gcc-arm-10.3-2021.07-x86_64-aarch64-none-linux-gnu/bin kernel_target = Image kernel_file = Image-devel dtb_path = dtbs_devel config_file = $kdt_boards/vim4_arm64_defconfig ramfs_file = initramfs-linux-devel.img update_ramfs = mkinitcpio -k $version -g $ramfs_file on = kasa --alias Strip_9BA6 --type strip on --name P2 off = kasa --alias Strip_9BA6 --type strip off --name P2 And my workflow to develop the kernel is as follows: $ export board=vim4 # Do some kernel changes $ kb config # Configures the kernel $ kb build # Builds the kernel $ kb scp vim4 # Copy the kernel, modules and device trees to my VIM4 board using rsync and scp # Reboot the board using ssh or issue: $ kb off ; sleep 2 ; kb on # Power cycle the board if reboot by ssh is not available This tool has many more features, like updating kernels in image files and removing Gerrit "Change-id" from patch files. In the near future, I will add the following: - Check a series of patches before upstreaming. Build the kernel with every patch in a patch series and check for building warnings, checkpatch, sparse, etc. - Device tree tool to help to upstream new boards to the kernel mainline. Like, find device nodes from a device tree that don't have a driver for it and list Kernel configs needed by the device tree. Happy coding Thanks Lucas _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
