AWS EduKit restore factory firmware
-
@ksprayberry Make sure you are in the correct AWS region. The test button on the MQTT page won't throw any errors or output if you're not in the correct region.
-
ok thanks. i used the "us-west-2". Let me check again.
-
@greenleaf Woohooo! That was it! I changed it to the North Virginia and it worked. Of course now after its working, I kind of fee like Ralphy on the Christmas Story after getting his Little Orphan Annie Secret decoder ring...."Be sure to drink your Ovaltine" a crumby commercial? SOB!" No, thank you, I was so close and it was something small.
-
@ksprayberry Don't feel bad, I slipped on the exact same banana peel. Writing technical workshop documentation is hard. I've been sending suggestions to the developer on github with some ideas about how to make this easier for new users.
What would be really amazing is the UIFlow experience, but with the AWS features enabled. Maybe someone could whip up a micropython module that would handle the AWS registration and key exchange interactively.
-
@greenleaf I would love for this to all be baked into the UIflow environment somehow or the provisioning baked into the M5Burner even somehow. I really enjoy working in it.
-
@greenleaf I spoke too soon. I'm stumped on the next example. Everything looks right, I can see the output from the M5 at the command line, I even think the messages are coming in to AWS, I can see the activity, but I don't seem to be able to change the state of the M5.Any tips?
-
@ksprayberry I must confess, I stopped the tutorial after getting Blinky Hello World working. I ended up flashing the device with UIFlow instead as it's much more user friendly.
-
@greenleaf It is that indeed. I can't help but think there are a few bugs and holes in the tutorials that will shake themselves out in the weeks to come.
-
In the meantime if you want to play around with AWS and MQTT I wrote up this how to guide for setting it up in UIFlow:
https://community.m5stack.com/topic/2688/mqtt-config-for-aws-iot-core-solved
You can both publish and subscribe to topics if you follow those steps. You do need to flash your device with the UIFlow image though.
-
@greenleaf Thank you! I'll give it a go and check it out.
Thanks! -
I wasn't aware of this forum, so my apologies if you didn't receive a solution right away.
To flash the factory firmware:
cd /<<PATH_TO_REPO>>/Core2-for-AWS-IoT-EduKit-Factory-Firmware idf.py build flashThe tick/pop you hear is the sound of the device rebooting over and over since there's no firmware (after erasing the flash). It's not bricked.
All the links on the instructions as of a week ago all point directly to the us-west-2 region so you don't get taken to your default region by accident. Hoping that helps all users.
Since there appears to be a lot of interest in UIFlow, we will prioritize getting that going in partnership with M5Stack. I really appreciate the feedback.

@rashedtalukder This helps, 1) but what is the process to bootstrap the device after Getting Started worked, when it doesn't even turn on, or change the dead device behavior where it doesn't tick or do anything anymore to take this firmware?
2) Can the AWS unit not use PlatformIO and perform as a regular Core2 device? -
Hi @infinitool ,
-
So when you unplug/plug the device in, the serial port doesn't even show up? If the port does not show up on your computer, then there are other issues. You can see these instructions or the link to Espressif's documentation for identifying the port for each OS: https://edukit.workshop.aws/en/blinky-hello-world/device-provisioning.html#identifying-the-serial-port-on-host-machine
-
You can use PlatformIO. As a matter of fact, the Getting Started guide explicitly uses PlatformIO: https://edukit.workshop.aws/en/getting-started.html.
