embOS trial & Rowley compiler

I downloaded "embOS 3.62a1 trial for ARM7/9 and Rowley compiler".
I am using "Rowley Crossstudio v14 build 5" for compilation your example "LPC2468_EA" and see an error:

C:/Program Files/Rowley Associates Limited/CrossWorks for ARM 1.4/gcc/bin/ld: ERROR: Lib/osT4LR.a(OSCOM2.o) uses VFP instructions, whereas THUMB Flash Release/embos.elf does not

Build failed

Then I change "ARM Architecture" in project options from v4T fo v5T and compilation is OK.
But v4T=ATM7TDMI , and v5T=ARM9TDMI.
LPC2468=ARM7TDMI-S processor.

Question: There are no libraries for ATM7TDMI. There are only for ARM9TDMI. Am I right?

I just checked the embOS project with an older Rowley CrossStudio version and the latest Rowley CrossStudio version

The embOS start project for LPC2468_EA compiles in all configurations without any problem.

Did you make any changes to the embOS start project? Could you please download the latest Rowley CrossStudio version?
