I followed steps found here to install an other GCC toolchain .
Now the compilation is working and I have the "OdriveFirmware.elf".
But now I have a jtag error :
Runtime Error: /usr/share/openocd/scripts/target/stm32f4x.cfg:32: invalid command name "jtag_ntrst_delay"
in procedure 'script'
at file "embedded:startup.tcl", line 58
at file "/usr/share/openocd/scripts/target/stm32f4x.cfg", line 32
make: *** [flash] Error 1
So I can't flash the bord
Maybe this problem is caused by the GCC version installed...
