How can we force the toolchain to only use Thumb-16 instructions in ARM cortex-m0/3/4????
What does your favorite web search give you?
Anyway, some of the 32 bit instructions are needed as there is no 16bit equivalent.
Maybe share your intention.
I'm using a Beagleboard with gccI'm looking for the parameter to use to ask gcc to not use thumb instruction !!!
Google told me:arm-none-eabi-gcc --target-help
