FreeRTOS w/o BLE Support

[apage224]

If ns_power_config_t.bNeedBluetooth is disabled, FreeRTOS doesnt work. This is because ns_power.c powers down the xtal when in deep sleep. I'd like to run USB based examples with FreeRTOS.

Another related issue, is that setting clock speed to low-power mode (96 MHz) causes my task to never get called. This is just a simple example with a print statement in the RTOS task. If I start with higher clock speed and then lower inside my task this works. Not sure why setting lower clock off the bat causes issues. Perhaps it's related to adjusting the clocks prior to calling the scheduler?
