How do you set the CPU type?

Post by lslarry86 » Fri Aug 18, 2017 10:20 am

Can someone help me find the place where the Coldfire chip type is set in Eclipse?

I have the 5441x setup, which defaults to 54415. I have a board with a 54418 chip, and want to explore the CAU and AES encryption. I am measuring about 3 mS to diversify a key with both 54415 and 54418. I want to see how fast I can make that go with the 54418 and its CAU.

One first step would be to change the CPU type and see if the toolchain uses the 54418 CAU. I see "-mcpu=54415" in the project Properties C/C++ Build Settings, but the window is read-only and I don't see where to change it.

What hardware are you running that has a 54418?

The cpu type is set in the make files...

try nburn\mod5441x\make\ldflags.mak
