![]() The resulting binary images are placed in the project directory. If you have 4 CPUs available, then you can do the following: $ make -j 4 If you have multiple CPU cores available, you can use the "-j" switch to increase the number of parallel threads used and speed up the build. U-boot is not a very large project to build, so this usually doesn't take very long on most computers. This depends on the board, based on the following table: BoardĮDM1-IMX6 Solo, EDM1-IMX6 Dual Lite, EDM1-IMX6 Quadįor example, if you were using PICO-IMX8M-MINI: $ make pico-imx8mm_defconfig ![]() Now configure u-boot for the target platform you are using. (Or whichever branch you wish to use) Configure U-boot for your target platform $ git clone Ĭheckout the stable branch: $ git checkout tn-imx_v2018.03_4.14.98_2.0.0_ga-stable If you want to work with the latest code, some of which might not be completely tested, you can use the branch ending in -next.

Once you have the toolchain installed, make sure that the ARCH and CROSS_COMPILE environment variables are set correctly so that these are used to build U-boot.įor 32-bit ARM targets (i.MX6UL/ULL, i.MX6, i.MX7): $ echo $gcc -versionĪrm-linux-gnueabihf-gcc (Linaro GCC 6.4-2018.05) 6.4.1 20180425 Ĭopyright (C) 2017 Free Software Foundation, Inc. ![]() For this, please refer to the following article. We use different toolchains depending on the processor architecture (32-bit or 64-bit ARM). You need to set up a toolchain to use to build U-boot. This article assumes that you are building U-boot from the TechNexion u-boot repository. This article takes you through the process of downloading and building U-boot yourself for your target platform. Customizing U-boot for your platform is sometimes necessary in order to add features, change the boot splash screen, and enable new hardware.
