Hi Ogra,
Thanks your help a lot !!
The uboot.env is a file I miss, and now I can build an image successfully.
^0^/
I also wonder why don't we provide some gold examples / guides to instruct
how to build the gadget snap for the specific arch, especially the gadget
couldn't created by snapcraft.
I am sure we will do exactly that it is just that right now gadget snap are
not finalized and the tooling around it is not fully implemented.
I plan to provide sources for building gadget snaps for all supported
platforms. From there you can fork and tweak as little or as much as you
want.
Best regards

Cheers,
Woodrow,

there are multiple issues with your gadget snap ...
in your snap.yaml you define two files that do not exist:
...
- path: boot-assets/bootloader.bin
...
- path: boot-assets/u-boot.bin
we also do not support any text files for configuring the bootloader any
more, you need to create a uboot.env (and adjust your uboot build time
configuration to use and find it):
#define CONFIG_ENV_SIZE SZ_128K
#define CONFIG_ENV_IS_IN_FAT
#define FAT_ENV_INTERFACE "mmc"
#define FAT_ENV_DEVICE_AND_PART "0:1"
#define CONFIG_SYS_REDUNDAND_ENVIRONMENT
(in include/configs/$your-board.h, note that FAT_ENV_DEVICE_AND_PART
needs to point to your vfat partition that holds the uboot.env file)
the uboot.env needs to be created using the mkenvimage command either
from your uboot tree (it gets built in the tools directory) or from the
u-boot-tools package in the archive:
mkenvimage -r -s 131072 -o uboot.env uEnv.txt
(note the options are not optional ;) -r and -s 131072 are mandatory)
and change "- path: boot-assets/uEnv.txt" to "- path:
boot-assets/uboot.env" in your snap.yaml
first see if it works better with the adjusted gadget snap and the very
latest ubuntu-device-flash from
http://people.canonical.com/~mvo/all-snaps/
if there are still issues then we can go through your kernel snap ...
ciao
