- This is the processor type of your CPU. This information is used for
- optimizing purposes. To build a library that will run on all ARMCPU
- types (albeit not optimally fast), you can specify "Generic Arm" here.
- If you pick anything other than "Generic Arm", there is no guarantee
- that uClibc will even run on anything other than the selected
- processor type.
-
- Here are the settings recommended for greatest speed:
- - "Generic Arm" select this if your compiler is already setup to
- optimize things properly, or if you want to run on pretty much
- everything, or you just don't much care.
- - For anything else, pick the ARM core type that best matches the
- cpu you will be using on your device.
-
- If you don't know what to do, choose "Generic Arm".
