Hi,
When building the firmware it should report the arm-none-eabi-gcc version used at the beginning, something along the lines of:
Using CC = /home/flixr/gcc-arm-none-eabi-4_7-2013q3/bin/arm-none-eabi-gcc
Using LD = /home/flixr/gcc-arm-none-eabi-4_7-2013q3/bin/arm-none-eabi-gcc
Using CP = /home/flixr/gcc-arm-none-eabi-4_7-2013q3/bin/arm-none-eabi-objcopy
Using DMP = /home/flixr/gcc-arm-none-eabi-4_7-2013q3/bin/arm-none-eabi-objdump
Using NM = /home/flixr/gcc-arm-none-eabi-4_7-2013q3/bin/arm-none-eabi-nm
Using SIZE = /home/flixr/gcc-arm-none-eabi-4_7-2013q3/bin/arm-none-eabi-size
GCC version:
arm-none-eabi-gcc (GNU Tools for ARM Embedded Processors) 4.7.4 20130913 (release) [ARM/embedded-4_7-branch revision 202601]
what does it show?
Cheers, Felix
