So all a57 and a53 (as well as big.LITTLE) contain the CRC unit? I use the a72/a53, but I use it as a common intersection for software for multiple products. One has an a72 and one has an a53, so it's not a true bigLittle configuration. I could see someone try this using this tune as well. --Mark > BASE_LIB_tune-cortexa57-cortexa53 = "lib64" > > > >
