I found the rayeager board always hang in the system boot process or when cpufreq change. When check the BSP code[0] from ChipSpark, I found the current vdd_arm voltage is too low and so is the vdd_logic voltage, which should be modulated by PWM3. So I increase the vdd_arm voltage and enabled pwm3 as a pwm regulator here.
