Refer to the "Built Images" section of the Quickstart pertaining to the specific release you are using for clarification on image names.Įxample Output # YOCTO_IMAGE in the instructions below refers to the Yocto image name that was used to build the image, and YOCTO_MACHINE refers to the machine that was selected to build the image. Note that the names of the images differ between releases. Pre-built images are available on PHYTEC's Artifactory. If you have built your own images, then the images are located in: /build/arago-tmp-external-linaro-toolchain/deploy/images// If you do not have SD card access under Linux then copying the bootloader and mounting the root filesystem on SD/MMC card will not be possible. SDHC SD card, at least 4GB for PHYTEC's TISDK release imagesĬreating a bootable SD card requires an SD card reader operational under Linux to format and access the Linux partition of the card.You will need the following to complete these instructions: This guide explains how to create a bootable SD card for the ph圜ORE-AM65x Development Kit using Linux.
