For example, compiling an Armv8 kernel on an X86 computer. The following setting is applicable when you configure and build kernel on a different architecture from the target.

Enable environmental setting for cross-compiling.

Change directory to flexbuild_/packages/linux/linux.

Step 3 Enable system monitoring unit and build kernel This generates the following images: rootfs_lsdk_yocto_tiny_ (~22M), lsdk_yocto_tiny_LS_b, and firmware_uboot_sdboot.img.įor example: rootfs_lsdk2004_yocto_tiny_ (~22M), lsdk2004_yocto_tiny_LS_b, and firmware_lx2160ardb_rev2_uboot_sdboot.img Run the following commands to generate Yocto-based tiny userland: This step is needed in case source/config has changed.

Add “stress” package to ' IMAGE_INSTALL_append' parameter of local_arm64_nf file available in flexbuild_/configs/yocto/ folder.

Run the following commands to extract Flexbuild files from tar archived file.Enter login details, accept the agreement to download the Flexbuild source tarball in the name format flexbuild_.tgz. On a Linux machine, download Layerscape Software Development Kit.Step 1: Download Flexbuild and add packages in Yocto tiny Validate stress package and measure CPU temperature before and after stress

itb image from TFTP server to Layerscape board Enable thermal monitoring unit and build kernel.Download Flexbuild and add packages in Yocto tiny.However, these steps are applicable to all Layerscape devices. Steps are explained with an example of LX2160A SoC. The below steps describe how to measure CPU temperature and how to stress individual cores of CPU.
