Thank you for your valuable reply, I followed what you said above, and
now it seems really related the compiler's flags.

I have passed compiling for the VEXPRESS with dcscb, I will compare the

It seems we need add the related dependency for ARCH_VEXPRESS (I am just
analyzing, may get final result today).


Thanks.
