2017.3 PetaLinux: Change to the name of the FIT image (image.ub) in the petalinux-config menu not reflected once images are built

描述

In PetaLinux 2017.3, If I change the name of the FIT image (image.ub) in the petalinux-config menu, it is not reflected once the images are built.

解决方案

This is due to kernel_image bootargs not updating. 

You can work around this issue using one of the methods below.

Method 1: 

Modify the FIT image name in platform-auto.h which is specified in the petalinux-config menu.

  • First copy the Extra U-boot env settings from <proj-proj-root>/project-spec/meta-plnx-generated/recipes-bsp/u-boot/configs/platform-auto.h to <proj-proj-root>/project-spec/meta-user/recipes-bsp/u-boot/files/platform-top.h
  • Now modify the kernel_image to match with the FIT image name specified in the petalinux-config menu as highlighted below:

    "default_bootcmd=run uenvboot; run cp_kernel2ram && bootm ${netstart}\0" \
""


Method 2:

Change the name in the petalinux-config file as shown below.

The PetaLinux tools will then update the kernel_image name in the U-Boot args.

CONFIG_SUBSYSTEM_IMAGES_ADVANCED_AUTOCONFIG_KERNEL_IMAGE_NAME="myimage.ub"
