Hi,

I was looking for fine tuning the compiler flags for GCC [1], is TI8148 processor armv7 or armv7-a ?

Thanks,

Hi Mike,

I think it should be armv7-a

DM814x has Cortex-A8 ARM r3p2 core:

Also linux drivers examples are build with armv7-a:

ti-ezsdk_dm814x-evm_5_05_02_00/example-applications/linux-driver-examples-psp04.04.00.01/Rules.make

#add cflags
CFLAGS += -march=armv7-a -mcpu=cortex-a8 -mfpu=neon -mfloat-abi=softfp
