I have a core that is connected and can receive certain firmware that I push to it. Simple .ino files like blinking an LED get pushed (flsahing magenta) and it works fine.
However, when i am trying to create an app based off the aws SDK for arduino (https://github.com/awslabs/aws-sdk-arduino) the code verifies, saves, and says that it is pushing to the device however the device does not flash magenta. It is as if the code was not sent even though the build IDE is saying it has been. The spark continues to run with whatever flash was previously on there so I know it’s not being pushed.
I have tried a hard reset and that doesn’t work. I only got my core last week so i’m presuming I am on the latest (Sept 9).
1.) Try flashing a smaller program, just in case the application you’re flashing is too big (over 108KB) for the Core.
2.) Make sure you can send non-flash commands to your core, does it show up as online in your list of cores in the IDE? (Is it breathing cyan on the screen as well?)
3.) Make sure you’ve starred / selected the core in your list as the target to flash
4.) Double-check to make sure there isn’t a small triangle shaped warning icon near the build info that would indicate an issue.
As mentioned in my original post, small programs do flash correctly. The blink LED app is an example of code that flashes correctly. Is there a way to see what the size of my compiled code is?
The core is showing up as online, also proven by the fact that I can push simple code to it.
1.) I managed to push the sample code twice to the core. One thing the sample code is doing is to take over the core RGB led upon boot up and i could not tell the OTA progress until it’s completed.
2.) I don’t have the AWS stuff set-up to test but i managed to reflash a couple of times.

3.) How do you verify that the old code is still running? I see that my OTA flashes is consistent but the code interacting with AWS might be causing the issue.
I am flashing the device via spark web build… am I right in saying you are doing it via USB? Perhaps I should try that method?
I know it’s the old code because the old code was flashing the LED on/off every second, and it continued to do so even after the spark build IDE was saying that my new AWS code was pushed to the device.
I’ve moved over to usnig the spark-cli.
So,
When I compile the samples/SparkGetItemSample.ino file + all the cpp/h files the size is 76k and flashes
When I compile the samples/SparkPutItemSample.ino file + the cpp/h files it ends up at 109k and fails
I have no idea how to reduce that code so I’ve added an issue to the github project. Thanks all!
