Hello all,
I have a red board Artimes ATP. I have a BLE application
I uploaded an arduino code to it and gets uploaded fine but when I open the serial monitor, I get the following error

Please help!

The 'fault exception' happens when memory is accessed that is not supposed to (e.g. protected). Often the result of an uninitialized pointer or exceeding allocated memory. It might be that a begin() or init() call was not performed.
You can look at https://os.mbed.com/docs/mbed-os/v6.15/ ... -dump.html how to get an indication of what part of the code to look at.

Else share your source and we can see whether we can help.

Hi Paul,

The weird thing is that I uploaded the same source code into another red artemis ATP board and worked fine.

The source code is simple, it blinks the built in led by a button in a mobile app.

only one difference between the two boards is that one has SVL boat loader version 3 and the other has version 5.

The source code is attached,

Thanks,

Mousa,

I can not find it directly, but there was a problem with an SVL version that was not disabling/stopping a timer before it jumped to running the user program. It then caused an error. Try to update the SVL to the latest version https://github.com/sparkfun/Apollo3_Uploader_SVL . I will look to see whether i can a link to the earlier problem.

This is the error message I am getting for the uploaded source code above:

I have just tried your source code on my ATP (SVL 5) and that works without a problem.

The issue I was referring to in an earlier post was https://github.com/sparkfun/Arduino_Apollo3/issues/388. Try updating the SVL.bin with the link provided before or https://github.com/sparkfun/Artemis-Firmware-Upload-GUI.

regards,
Paul
