Hi,

I have a Freescale FRDM-K64 board. I cannot get the samples/hello_world/microkernel to work. Compiling with this:
# make O=out-arm BOARD=frdm_k64f

It compiles fine and the out-arm/zephyr.bin can be dropped into the MBED folder (for easy programming) just fine. However I can see actually flashes the board (because the previous program is overwritten) but it's not showing "Hello World!" as I'd expect on the /dev/ttyACM0 (Linux).

What am I doing wrong?

Kind regards
Anders

Does anyone have a working working zephyr.bin for the FRDM-K64 board where printf/k is working? I'd like to see if it would work on mine.
Kind regards
Anders

Got it working using minicom and no flowcontrol...
