Recently the customer returned three machines, the main problem is that the machine is start for a period of time to restart frequently!Ifind the log that system crash!we use cpu:imx6dl,2GB DDR3,Android 4.4.2,kernel:3.0.35！The system crashed about a minute after startup!At this point, the CPU frequency is reduced by half,I have the following questions:
(1)Why is the CPU frequency reduced by half after starting up?What causes it?Can I set the unfixed frequency?Where to change?(start cpu frequency is 800HZ after about a minute is 400HZ;
(2)When CPU frequency reduce 400HZ，system will restar！At this time, if I change the following ARM voltage from 1.075v to 1.17v, there will be no restart！I checked the official website for 6DL Kernel: 3.0.35. The ARM voltage here is 1.075v！I also tested the voltage correctly！However, I checked the official website and found android 5.1 version with 1.17v Settings！How much is the 6DL Kernel 3.0.35 set here? Is there any parameter data?
we change the image below!1075000 change 1175000
I checked the official website and found android 5.1 version with 1.17v Settings！
