Thank you very much for your answer. I confirm that I have completed the activation of the software, as shown in the screenshot below. The compiler I am using is version 5.06. Not the default version 6.0. Could it be because of this issue?
Yes, that is the issue. The community edition license only enables Arm Compiler 6.
Arm Compiler 5 will be in the default (legacy) evaluation mode, which is limited to 32KB.
Okay, I understand. Thank you for your answer.Wish you all the best.
Excuse me，I would like to inquire about an issue that occurred after switching to AC6.When I switched from AC5 to AC6, I encountered a problem where I couldn't find the signbit function. Is it because there is no macro definition for signbit in AC6? How should it be used?
“.axf: Error: L6218E: Undefined symbol signbit (referred from fastmathfunctions.o).”
It is defined in the provided math.h, and I tested a simple example without issue.
Can you show an example that fails?
