@lucazizolfi can you connect to the board with screen/minicom and check if it starts blinking?

@landgraf I flashed the board with blinky's image and now it works properly, the LED flashes

This causes by ea7cea6c8a7e7184f275a9a56cfa6873b1716e1c and following df59d82772fd67b8fc1d30d97917305be0f49675

@brgl @agherzan I think we should change the behaviour of the switch. CI should add ONIRO_ENABLE_ACM0 or similar not users add ONIRO_NO_ACM0 to make blinky working again

@lucafavaretto workaround is as simple as: echo ONIRO_NO_ACM0 = "1" >> conf/local.conf

Lowering severity

@landgraf if the workaround works (we gonna test it today) the issue will change iteration to July or will be fixed in the current iteration anyway?

@landgraf the workaround indicated above (the change in the conf/localconf file) is to be done before or after launching the build?

either before or ONIRO_NO_ACM0 = "1" bitbake ....

added SeverityNormal label and removed SeverityCritical label

@lucafavaretto This is not a regression though - it used to work like that ever since I started working on oniro zephyr. The app waits for the ACM0 to be opened on the host. The QA team asked me explicitly to keep it this way.

@brgl can you elaborate please? which QA team? Both Oniro and Zephyr have in their documentation something like "After flashing, the LED starts to blink. Blinky does not print to the console.". from user's point of view this "feature" is completely broken. As I mentioned this logic should be reverted to "blink by default", wait for connection if flag has been specified

@landgraf if you take current dunfell oniro and build the blinky image, it won't start blinking until you start a console on the ACM0 device. It was Chase Qi who requested it be kept the same in kirkstone IIRC. I don't often look at the docs but maybe they're wrong. I agree it's a broken idea hence this variable.

I don't protect it's a regression (I'm pretty sure it's not) but that should be fixed anyway

If you agree - the fix is super easy - just reverse the logic of that variable. Have ONIRO_USE_ACM0 with a positive logic instead.

I do. This was my initial suggestion. We should communicate the change to all interested teams though
