Bug Description

I built an image as follows:

sudo ./ubuntu-device-flash --verbose core 16 -o rpi2-all-snap.img --channel stable --enable-ssh --gadget canonical-pi2 --kernel canonical-pi2-linux --os ubuntu-core

and then wrote it to the SD card and booted it in a Pi 2.

The heartbeat is on the disk activity LED (green) and disk activity makes the power LED (red) blink.

AFAICT this is fixed with the latest pi2 images.

I just installed Ubuntu Core on my pi2, and it has the heartbeat on the green LED.

In /boot/uboot/config.txt (https://github.com/snapcore/pi2-gadget/blob/master/configs/config.txt), these lines have 'heartbeat' and 'mmc0' reversed:

dtparam=act_led_trigger=heartbeat
dtparam=pwr_led_trigger=mmc0

while landing this fix in the tree is trivial, it will sadly not end up on any devices until https://forum.snapcraft.io/t/updating-bootloader-assets-in-the-gadget-snap is fixed (gadget snap updates currently do not update bootloader bits)

The blocker for this bug (gadget updates) is still under development but is now very nearly complete. I'm just stating this for the benefit of anyone interested in this issue.

It's a very complex topic of how to perform updates of certain kind in the field and while it takes a while to complete, the code will allow this bug to be fixed without requiring anyone to re-flash their devices.

This should be unblocked now, updating the gadget snap will attempt to update the boot assets.

I just discussed this issue with Maciej and the logic is all there. The Raspberry Pi gadget needs to contain update.edition: 1 in the appropriate structure to trigger the update.

Re-assigning to Paolo, the snapd side is now fixed. I think this needs a gadget declaration change and it should be good to go.
