Hi all,
As I used new ubuntu-image (0.14+real1) to create my armhf image, I also
got the same error as well. In order to try to fit the new spec of
gadget.yaml, I modified the gadget.yaml as follows:
device-tree: actduino_bubble_gum_sdboot_linux.dtb
volumes:
roseapple-pi:
schema: mbr
bootloader: u-boot
structure:
- name: bootloader
size: 4M
content:
- image: bootloader.bin
offset: 2097664 #4097*512
- image: u-boot.bin
offset: 3145728 #6144*512
type: bare
- name: system-boot
type: 0C
filesystem: vfat
filesystem-label: system-boot
offset: 8388608
size: 128M
content:
- source: boot-assets/
target: /
And then this can avoid above the error during image creation. However, the
generated image lost the content of bootloader.bin & u-boot.bin at
the specific offset. So I think it may not follow the correct spec of
gadget.yaml. Can anyone help us to resolve the problem? Thanks.
Regards,
Woodrow
