Hey guys,
I'm new here and I'm stuck.
I'm working now on a Mifare Reader, MFRC522. I trying to make it read some information, but first, I want to test if I'm having some kind of communication.
I'm building my project and there's this error:
"Building target: chicago.axf

I have no idea what I can do about it. I already read topics related to it but anything seems to fix the problem.
Could anyone help me?
