Hello Martin
Thanks for your answer.  Did not look at it yesterday, as it was sunny
in the UK :).  I also tried arm-softfloat-elf and got the same error. I
do not know about switching the EABI.  Do you know how to include
newlib? Could you please post your linker script / makefile as I am
having linker problems ..not finding file.

Many thanks

Billy
