Hi Miguel,
Could you tell me what the project and chip you are using now?
You can send your project to us, then I can help you to check it.
Here one post for your reference:
K60D100 - N0 source available for 0xfffffffe
Normally, it is caused by the source file problem, but for details, we need to check the project.
Have a great day,
Jingjing
