adding `-nmagic` to linker parameter fixed the issue; the booloader is not overridden \
and only necessary binary is uploaded.
Interesting I need this option for stm32f1 but not for stm32f4

** [tickets:#250] Raw ELF is uploaded**
**Status:** new

Hello, i have an issue with "Open On-Chip Debugger 0.10.0". the following:
~~~
/usr/bin/openocd -c "tcl_port disabled" -s /usr/share/openocd/scripts -c "gdb_port \
3333" -c "telnet_port 4444" -f debugger.cfg -c "program \"compiled.elf\"" -c reset -c \
shutdown ~~~
works fine if the binary start from the beninning of the flash(0x08000000); but if i \
start from 0x08004000 for example, instead of the binary, the raw ELF will be \
uploaded starting from position 0x08000000. Thats it, the file is uploaded 1:1 \
instead of coverted to binary and offested of 0x4000.
My suspicion is that the elf format, despite the extension and correctly starting \
with bytes 0x45 0x4C 0x45 (ELF) is seen as binary and uploaded at the default flash \
address.
Interestingly I have another project that works fine with the exact same command; \
main differences are that start from 0x08040000, and is targeting a stm32F4 instead \
of a stm32F1
debugger.cfg:
~~~
source [find interface/stlink-v2.cfg]
transport select hla_swd
set WORKAREASIZE 0x10000
source [find target/stm32f1x.cfg]
reset_config none separate
~~~
