==Building Boot Image==

{{ImportantMessage|text=The following procedure may be used just during the development stage (as an example, for modifying and testing just some part of the overall binary like u-boot). The Yocto build should be used for creating the deployment or production binary artifacts.}} ===Quick reference===

=== Build boot image === To build the binary boot Image is pretty complex.Too much component are needed and the image structure may change if the <code>optee</code> or other security features are used. To make an easier boot Image build we '''strongly''' suggest to use the Yocto build system. Before execute the setup of Yocto, see [[DESK-MX9-L/Development/Building_the_Yocto_BSP | this page]]. Each time there are some changes on u-boot, the u-boot references in the Yocto recipes have to be changed.Edit the u-boot reference on:* <code>sources/meta-desk-mx/recipes-bsp/u-boot/u-boot-desk_git.bb</code>* <code>sources/meta-desk-mx/conf/machine/include/desk-common-mx93.inc</code>* <code>build-*/conf/local.conf</code> Remember to update the follow variables: * <code>SRCREV:pn-u-boot-desk</code>* <code>SRCBRANCH:pn-u-boot-desk</code>* <code>UBOOT_SRC:pn-u-boot-desk</code> to use the different repository/branch and revision. After the u-boot sources has been updated, execute the build of boot binary with the following steps * setup the Yocto environment if not already up* execute the build of boot binary with follow command <code>bitbake imx-boot</code>.* the binary generated is present on <code>tmp/deploy/images/<machine-name>/imx-boot</code>.

To flash the boot image on uSD execute the following steps:* connect the uSD to the MVM* get the device name with <section endcode>lsblk</code> command.* flash the binary to the uSD with follow command <code>sudo dd if=imx-boot.bin of=/dev/sdX bs=Body1k seek=32 conv=fsync</code> (replace <code>sdX</code>with your device)
