[arm-gnu] difference between values from readelf and GDB

[Vaclav Peroutka]

Hello,
I have simple linker script for Cortex M3 below. If I use arm-none-eabi-readelf, I can get correct values for _etext, _data, _edata. But if I run arm-none-eabi-gdb with this ELF, I see all values wrong. What is wrong here ?

Thank you in advance,
Vaclav
