Hello Martin |
| 43 |
Thanks for your answer. Did not look at it yesterday, as it was sunny |
| 44 |
in the UK :). I also tried arm-softfloat-elf and got the same error. I |
| 45 |
do not know about switching the EABI. Do you know how to include |
| 46 |
newlib? Could you please post your linker script / makefile as I am |
| 47 |
having linker problems ..not finding file. |
| 48 |

Many thanks |
