stm32f4_disco issues

Hi All,

I'm attempting to flash the samples/basic/blinky/ project on the
stm32f4_disco board, but am running into issues.

Here's a list of steps I run through:
make BOARD=stm32f4_disco -C samples/basic/blinky/
make BOARD=stm32f4_disco -C samples/basic/blinky/ flash

Then nothing happens on board (no LED blink after power cycle). I
attempt to debug
make BOARD=stm32f4_disco -C samples/basic/blinky/ debugserver
gdb -tui -ex "target remote :3333" ../outdir/stm32f4_disco/zephyr.elf

For help, type "help".
Type "apropos word" to search for commands related to "word"...
Reading symbols from ../outdir/stm32f4_disco/zephyr.elf...done.

0x0800133d in _main ()
at /home/psidhu/src/zephyr/zephyr-upstream/kernel/init.c:190

It seems like execution is always stuck on _main(), but I don't know
why. Does anyone have any idea what's going on / if I'm doing
something wrong?

Thank you,
