Minized: INITRAMFS as root filesystem

niborz
niborz 7 months ago

Hello,

 

I want to build Petalinux 2020.2 for the minized with an INITRAMFS as rootfs (ideally it should be stored into the u-boot fitImage which i believe is called image.ub by petalinux).

I downloaded the 2020.2 bsp from Avnet website and started a new project.

After changing the "Root filesystem type" to INITRAMFS in "Image Packaging Confiugration" using the petalinux-configure command, i get the following dependency loops when building:

 

$ petalinux-build -c avnet-image-minimal

These are usually caused by circular dependencies and any circular dependency chains found will be printed below. Increase the debug level to see a list of unbuildable tasks.

 

Identifying dependency loops (this may take a short while)...

ERROR: Command execution failed: 1

 

Summary: There were 3 ERROR messages shown, returning a non-zero exit code.

ERROR: Failed to build avnet-image-minimal

Building for an EXT4 rootfs yields no such error.

Is there something else to do for  the "Root filesystem type" option to work ? Maybe what i want to achieve must be configured somewhere else ?

 

Thank you

    Hi Robin,

     

    These dependency loop errors are because the last OS image to be built was for using an EXT4 based rootfs (when the BSP was created) and the change to a RAMdisk rootfs is either incorrect or incomplete.  There should be a 'rebuild_minized_sbc_base.sh', 'rebuild_common.sh', and 'config.boot_method.${BOOT_METHOD}.sh' bash shell scripts in the PetaLinux project folder.  You can simply run the 'rebuild_minized_sbc_base.sh' bash script to rebuild all of the OS image binaries for the PetaLinux project.  If you want to examine how the different OS image type (INITRD vs EXT4) is configured for build you can look in the configure_boot_method () section of the 'rebuild_common.sh' script and the 'config.boot_method.INITRD.sh' bash script to see PetaLinux project configuration changes needed to change from EXT4 to INITRD OS image for the image.ub file.
