hi all, i found a strange phenomenon: i input reboot command, then i can see something show on the screen before kernel start. after kernel start, screen turn off, nothing can be seen. kernel start may restart something lead to screen turn off. why i turn off the power then turn on but nothing can be seen on the screen, then do reboot image can show on screen? what the different between turn off the power restart system and reboot commond to restart system? i also found that IPU2 frequency is very low log as following: [HOST] [IPU2 ] 3.913926 s: *** SYSTEM: CPU Frequency , i need to set the frequency of IPU? best regards!
