Target Process does not show Cortex-a53

[david_kempert]

I am trying to select a target processor in CodeWarrior 11.4.0 and the Cortex-a53 does not show up in the drop down list. How do I select this processor?

[Pavel · Accepted solution]

CodeWarrior has removed support for customizing target-specific compiler optimizations, due to no perceived benefit in doing so.
You can still do that, though. Go to C/C++ Build -> Settings -> Tool Settings -> Cross ARM C Compiler -> Optimizations -> Other optimization flags and add "-mtune=cortex-a53" to that text box. Then recompile the project.

See the following document about CodeWarrior 11.4.0:

https://www.nxp.com/docs/en/release-note/CW-ARMV8-RN.pdf

This CodeWarrior supports QorIQ LS-Series processors.

See the LS1012a, LS1043a and LS1088a Reference Manual.

These Reference Manuals shows that cores of these processors are Cortex A53.

That wasn't my question. I am using the LS1043a processor and want to select the cortex-a53 from the drop down menu from Properties->C/C++ Build->Settings->Tool Settings->Target Processor->Arm Family. Setting this adds -mcpu to the compiler command line, but Cortex-A15 is the highest core that can be selected. For now I am getting around this by selecting "Toolchain default" as the ARM family, and "armv8-a" as the Architecture.
