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.
