Jetson TK1 Build Helper
A streamlined Bash utility for building legacy U-Boot/Kernel sources on modern Arch-based systems. This script handles the "headaches" of building older code with modern GCC versions, including ncurses pathing, header conflicts, and DTC version checks.
Quick Start
(0) You might have to chmod build.sh:
Bashchmod +x build.sh
(1) Run the setup to install and create all nesessary things ./build.sh setup
(2) Either use the default config or open the menuconfig to configure your uboot.bin
Default config for TK1 ./build.sh default_config
Build using custom config: (1) configure : ./build.sh menuconfig (2) Build : ./Build
Command Reference
Command Description ./build.sh setup Installs dependencies (using pacman), fixes ncurses symlinks, and patches legacy scripts for modern GCC. ./build.sh default_config Applies the jetson-tk1_defconfig. ./build.sh menuconfig Opens the interactive configuration menu. ./build.sh clear Runs distclean to wipe all build artifacts and start fresh. ./build.sh (No args) The Build Command. Compiles using all available CPU cores.
Key Features
Header Safety: Automatically hides /usr/include/libfdt.h during the build to prevent conflicts with U-Boot's internal headers. Auto-Restore: Uses a trap function to ensure your system headers are restored even if the build crashes or is interrupted (Ctrl+C).
Modern Toolchain Patches: * Fixes the lxdialog check for modern Ncurses.
Forces scripts/dtc-version.sh to pass (ignoring version mismatches). Injects -fcommon via HOSTCFLAGS to handle legacy global variable definitions.
Requirements
Host OS: Arch Linux, CachyOS, or EndeavourOS. (you should be able to port it to any distro you want easily ) Target: Jetson TK1 (ARMv7).Toolchain: arm-none-eabi-gcc (handled by the setup command).
